EDUCATION

Einführung in die Rohstoffgewinnung

Abbau fester mineralischer Rohstoffe im untertägigen Bergbau

Nach dem in den vorausgegangenen AMS-Ausgaben im by Univ.-Prof. Dr.-Ing. habil. H. Tudeshki Rahmen der Weiterbildung die Fachgebiete „Rohstoffsicherung, Surface Mining and International Mining TU Clausthal | Germany Lagerstättenerkundung, Reservenberechnung, Geomechanik und Hydrogeologie“ als Voraussetzung für Planung von Bergbauprojekten ausführlich behandelt wurde, setzt die Weiterbildung dieser Ausgabe mit der Einführung in die Rohstoffgewinnung fort. Nach der Eröffnung des Themas in der vergangenen Ausgabe durch die „Bergbaurelevanten Lagerstättenmerkmale“ werden in dieser Weiterbildung die Verfahren der Rohstoffgewinnung im untertägigen Bergbau behandelt.

Abbauverfahren Die Verfahren, nach denen der Abbau von festen mineralischen Rohstoffen im Tiefbau vorgenommen wird, sind sehr vielfältig. Überspitzt kann gesagt werden, dass die Abbauverfahren in ihrer Erscheinungsform so vielfältig sind wie die Lagerstätten selbst. Bei der Auswahl eines Abbauverfahrens ist die Ausprägung der Lagerstätte und hier besonders die Teufenlage, die Mächtigkeit, das Einfallen und die Standfestigkeit des Lagerstätten- und Nebengesteins der Haupteinflussfaktor. Nur durch Abstimmung des Abbauverfahrens auf diese Lagerstättenparameter wird ein Abbau des mineralischen Rohstoffes wirtschaftlich und technisch möglich. Die Abbauverfahren können nach verschiedenen Merkmalen eingeteilt werden. Die Merkmale können in drei Ordnungen unterteilt werden. Merkmale der ersten Ordnung sind die Bauweise und die Dachbehandlung, Merkmale der zweiten Ordnung umfassen Angaben über die Verhiebsart und -richtung. Die Merkmale der dritten Ordnung geben letztlich Auskunft über die Abbauführung und Abbaurichtung.

i t a

l s n

a r T Merkmale der ersten Ordnung

n o

Eine grundsätzliche Einteilung der verschiedenen Abbauverfahren wird mittels der Bauweise vorgenommen. Die Bauweise beschreibt, wie ein abzubauender Lagerstättenabschnitt in Angriff genommen wird. Die folgenden Bauweisen sind möglich: • • • • •

langfrontartige Bauweise, stoßartige Bauweise, pfeilerartige Bauweise, kammerartige Bauweise und blockartige Bauweise.

Issue 01 | 2013

n o o

Bei der langfrontartigen Bauweise wird die Lagerstätte in einer Front von bis zu mehreren hundert Metern abgebaut. Die Abbaufront rückt dabei quer zu ihrer Erstreckung vor. Eine solche Bauweise wird bei großflächig abgelagerten, plattenförmigen Lagerstätten mit mäßigem Einfallen angewandt und ist typisch für den Abbau von Steinkohle.

s g

n i m

Wird die bestehende Lagerstätte in schmale Abschnitte, so genannte Stöße, eingeteilt, so wird dies als stoßartige Bauweise bezeichnet. Die einzelnen Stöße weisen dabei meist eine ein- bis dreifache Streckenbreite auf, können neben-, über- oder untereinander angeordnet werden und werden nacheinander abgebaut. Abbauverfahren mit stoßartiger Bauweise werden meist bei gangartigen Vorkommen des Erzbergbaus angewandt.

o c

Bei der pfeilerartigen Bauweise wird die Lagerstätte in Abschnitte, so genannte Pfeiler eingeteilt. Die Pfeiler werden durch vollständiges oder teilweises Umfahren hergestellt. Nachdem dieses Pfeilerstreckensystem aufgefahren wurde, kann in einem zweiten Arbeitsschritt damit begonnen werden, die Pfeiler und damit einhergehend den größten Teil der Lagerstätte abzubauen. Die Pfeiler können dabei je nach Ausprägung des Rohstoffvorkommens neben oder übereinander liegen. Die kammerartige Bauweise zeichnet sich durch das Herstellen von Kammern oder Örtern aus. Kammern und Örter sind gleichmäßig geformte Abbauräume mit einem lang gestreckten meist rechteckigen Grundriss. Wird der Hohlraum dabei in einem Arbeitsgang aufgefahren, entsprechen die Abmessungen also ungefähr denen einer Strecke, dann handelt es sich um Örter. Werden diese Abmessungen vor allem hinsichtlich der Höhe überschritten, so spricht man von einer Kammer. Eine Sonderform der kammerartigen Bauweise ist die so genannte Weitung.

www.advanced-mining.com

EDUCATION Die blockartige Bauweise ist beschränkt auf sehr mächtige Lagerstätten. Das Vorkommen wird in Lagerstättenabschnitte mit zum Teil beträchtlichen Abmessungen, so genannte Blöcke, unterteilt. Der durch den Abbau geschaffene freie Raum ist bei diesem Abbauverfahren im Gegensatz zum Kammerbau nicht zugänglich. Eine weitere Unterteilung der Abbauverfahren kann durch die verschiedenen Möglichkeiten der Behandlung der Firste während und nach dem Abbau vorgenommen werden. Unter diesem auch als Dachbehandlung bezeichneten Merkmal wird die Behandlung der lotrecht über dem Abbauraum anstehenden losen oder festen Massen verstanden. Die Möglichkeiten der Dachbehandlung sind: • • •

der Festenbau, der Versatzbau und der Bruchbau.

Beim Festenbau wird das den Abbau überdeckende Gebirge durch stehen gelassene Lagerstättenteile, so genannte Bergfesten, dauerhaft abgestützt. Die Festen werden im Gegensatz zu Pfeilern nicht abgebaut. Wird der Versatzbau angewendet, so wird den beim Abbau entstandenen Hohlräumen durch das Einbringen von Versatzbergen ein neues Auflager gegeben. Der Versatz sollte eingebracht werden, bevor es zu Setzungen des Gebirges kommt, damit eine geringe und bruchfreie Absenkung der Deckgebirgsschichten erreicht wird.

a r T

i t a

Merkmale zweiter Ordnung Nachdem die Abbauverfahren durch die Merkmale der ersten Ordnung bereits grob beschrieben wurden erfolgt durch die Merkmale der zweiten Ordnung eine weitere Spezifizierung. Merkmale dieser Ordnung sind die Abbau- bzw. Verhiebsrichtung, die Verhiebsart sowie die Abbauführung. Hierzu muss zunächst kurz erläutert werden, was im bergmännischen Sprachgebrauch unter Abbaubzw. Verhiebsrichtung zu verstehen ist. Im Gegensatz zur Abbaurichtung, die die Richtung beschreibt, in die sich der

Issue 01 | 2013

Die Verhiebsart beschreibt in welcher Weise die Abbaufront in Angriff genommen wird. Dies kann firstartig, strossenartig oder stoßartig geschehen. Die Abbauführung schließlich umfasst mehrere Merkmale. Sie beschreibt die räumliche Verteilung der Abbaubetriebe im Grubengebäude. Ein sehr wichtiges Merkmal in diesem Bereich ist die Unterscheidung ob es sich bei dem betrachteten Abbau um einen Vor- oder einen Rückbau handelt. Bei einem Rückbau werden ausgehend von einer Hauptstrecke zunächst die das Abbaufeld begrenzenden Abbaustrecken aufgefahren. Im weiteren Vorgehen wird das Wertmineral in einer rückwärts gerichteten Bewegung in Richtung der Hauptstrecke abgebaut. Beim Vorbau ist die Abbaurichtung von der Hauptstrecke wegführend. Die Abbaustrecken können dabei entweder vorher oder begleitend mit dem Abbau aufgefahren werden.

n o o

s g

n i m

o cAbbauverfahren mit langfrontartiger

n o Bauweise

Als Bruchbau wird das Verfahren bezeichnet, bei dem die Deckgebirgsschichten planmäßig zubruchgehen. Durch die beim Bruch auftretende Volumenvergrößerung des Haufwerkes wird der durch den Abbau und das Zubruchgehen entstandene Hohlraum gefüllt und dient somit den weiteren Gebirgsschichten als Auflager. Typischerweise treten beim Bruchbau Setzungen an der Tagesoberfläche auf.

l s n

Abbau im Großen bewegt, sagt die Verhiebsrichtung etwas über die Richtung des Hereingewinnens des Wertminerals im Kleinen aus. Die Abbaurichtung beschreibt sozusagen die Strategie des Abbaus insgesamt, während die Verhiebsrichtung die Taktik vor Ort beschreibt. Sowohl die Abbaurichtung als auch die Verhiebsrichtung kann streichend, fallend, schwebend oder schräg realisiert werden, wobei die schräge und fallende Richtung nur eine untergeordnete Bedeutung hat.

Abbauverfahren mit einer langfrontartigen Bauweise werden eingesetzt, wenn eine plattenförmige Lagerstätte mit großer Ausdehnung vorliegt. Beispiele für den Einsatz dieser Bauweise sind der Abbau der deutschen Steinkohle sowie der Golderzbergbau in Südafrika. Von praktischer Bedeutung bei dieser Bauweise ist heute nur noch der Strebbau. Beim Strebbau wird üblicherweise ein rechteckiger Flözabschnitt an einer langen Front abgebaut. Der als Streb bezeichnete streckenförmige Abbauraum wandert quer zu seiner Längserstreckung über die für den Abbau vorgesehene Fläche. Der Streb ist ein langer, schmaler Abbauraum von relativ geringer Höhe, der auf der einen Seite durch das Wertmineral und auf der Anderen durch den Bruch bzw. Versatz begrenzt wird. Die Höhe des Strebes ist abhängig von der Mächtigkeit des abzubauenden mineralischen Rohstoffes. Hinsichtlich der Dachbehandlung kann zwischen Bruchbau und Versatzbau unterschieden werden.

Abb. 1: Beispiel Strebbau [1]

diesen seltenen Fällen wird der Raum hinter dem Streb mit taubem Gestein aus der Kohlenaufbereitung, so genannten Waschbergen, verfüllt.

Die nachstehende Abbildung 1 zeigt den Strebbau, wie er im deutschen Steinkohlenbergbau angewendet wird. Ausgehend von den Hauptstrecken werden bei diesem Abbauverfahren die obere und untere Abbaustrecke (Kopfund Bandstrecke) aufgefahren. Der Streb wird durch ein so genanntes Aufhauen eingerichtet. Das Aufhauen legt die Abbaufront für den späteren Abbau frei und stellt die Verbindung zwischen den beiden Abbaustrecken her. Ausgehend von diesem Aufhauen bewegt sich der Streb rechtwinkelig zu den Abbaustrecken durch die Baulänge. Der Strebraum wird auf der rechten Seite der Abbildung durch den bereits ausgekohlten Bereich, den Alten Mann, begrenzt. Links des Strebraumes liegt die noch abzubauende Kohle an.

n o

l s n

i t a

Um einen Wetterzug durch den Alten Mann und damit einhergehend eine Entzündung von Restkohle zu vermeiden werden Streckendämme errichtet. In dem in Abbildung 1 dargestellten Beispiel wird die untere Abbaustrecke nach dem Durchgang des Strebes abgeworfen. Die obere Abbaustrecke hingegen wird für das nachfolgende Abbaufeld als untere Abbaustrecke erneut genutzt.

a r T

Der Bereich des Alten Mannes wird entweder mit Versatz aufgefüllt oder aber zu Bruch gehen gelassen. Beim Strebbau ist der Bruchbau üblich, nur ein geringer Anteil der weltweit im Strebbau gewonnenen Kohle kommt aus Streben in denen Vollversatz angewendet wird. In

Issue 01 | 2013

Ein weiteres Merkmal der Abbauverfahren mit langfrontartiger Bauweise ist die Abbaurichtung, bei der beim Strebbau die Richtung verstanden wird, in die sich der Streb als Ganzes bewegt. Im Bezug auf die Lage des Flözes im Gebirge kann sich der Streb in streichender, schwebender oder fallender Richtung bewegen. Eine Auswahl von Kombinationen der Abbau- und Verhiebsrichtungen zeigt die nachstehende Abbildung 2.

n o o

s g

Die Abbaue links in der Abbildung zeigen eine streichende Abbaurichtung mit schwebendem (oben) und fallendem (unten) Verhieb. Die Abbildung rechts zeigt ein Abbauverfahren mit einer schwebenden Abbaurichtung und einem schwebendem Verhieb

n i m

o c

Zur weiteren Beschreibung des Abbauverfahrens werden Aussagen zur Abbauführung getroffen. Ausgehend von einem Aufhauen wird der Streb zwischen der oberen und unteren Abbaustrecke ins Feld geführt. Werden die Begleitstrecken gleichzeitig mit dem Streb aufgefahren so wird dies als Vorbau bezeichnet. Bei einem Rückbau werden die Begleitstrecken zunächst in ihrer gesamten Länge bis zur Baufeldgrenze hergestellt. An der am weitesten von der ausgehenden Hauptstrecke liegenden Stelle wird dann das Aufhauen hergestellt und der Streb zurück zur Hauptstrecke geführt (Abbildung 3). Die nachstehende Abbildung 4 zeigt ein Beispiel eines langfrontartigen Abbauverfahrens wie es im südafrikanischen Golderzbergbau angewendet wird. Das Golderz wird in dem als Reef bezeichneten Flöz mit einer Mächtigkeit von rund 1 Meter abgebaut. Gegenwärtig werden in Südafrika Teufen von 4.000 m und mehr erreicht. Das Flöz wird abgebohrt und gesprengt, das

so freigelegte Gestein wird mit Hilfe von Schrappern zur Hauptfördersohle gefördert und von dort nach übertage transportiert. Ein Charakteristikum des südafrikanischen Golderzbergbaus sind die Pfeiler aus geschichtetem Holz, die die Tragfähigkeit des bereits ausgeerzten Bereiches unterstützen.

Stoßbau

Abbauverfahren mit stoßartiger Bauweise

i t a

n o

Die Abbauverfahren mit stoßartiger Bauweise zeichnen sich durch die Einteilung der Lagerstätte in Streifen oder Stöße aus, die in flacher Lagerung nebeneinander und in steiler Lagerung übereinander liegen. Erst wenn

l s n

a r T

ein Stoß vollständig abgebaut ist, wird mit dem Abbau des nachfolgenden Stoßes begonnen. Die wichtigsten Ausführungen dieses Abbauverfahrens sind der Stoßbau und der Firstenstoßbau. Diese beiden Varianten werden im Folgenden näher betrachtet.

Beim Stoßbau werden nacheinander mehrere Meter breite Stöße aufgefahren. Die nachstehende Abbildung 6 zeigt anhand des Beispiels Erzbergwerk Meggen einen Stoßbau bei flacher Lagerung. Ausgehend von einer Strecke, die durch den Erzkörper aufgefahren wird, werden zu beiden Seiten der Strecke Stöße in Angriff genommen. Nachdem ein Stoß vollständig abgebaut wurde, wird er versetzt. Im Anschluss kann ein neuer Stoß angegriffen werden. Die Abförderung des Erzes erfolgt durch die mittlere Strecke.

EDUCATION

Abb. 7: Prinzip des Strossenstoßbaus [Quelle: SME Mining Engineering Handbook 2nd Edition Volume 2, 1992]

Auch bei steiler Lagerung kann der Stoßbau eingesetzt werden. Diese besondere Art des Stoßbaus wird als abwärts geführter Stoßbau oder als Strossenstoßbau bezeichnet (Abbildung 7). Hierbei werden die einzelnen Stöße nicht nebeneinander sondern untereinander aufgefahren. Ausgehend von einer Wendelstrecke oder Rampe wird eine Strecke im Erzkörper aufgefahren. Im Erzkörper wird zudem ein Rollloch aufgefahren, durch das das Erz auf die tiefer gelegene Fördersohle verstürzt werden kann. Ist ein Stoß vollständig abgebaut, wird er versetzt und dient dem darunter zu gewinnenden Stoß als Firste . Der Versatz wird durch einen im Versatz mitgeführten Verschlag bis auf die zu versetzende Stelle transportiert. Allerdings gilt das Verfahren als verhältnismäßig leistungsschwach und teuer. Aus diesem Grund kommt es nur noch selten zum Einsatz.

Firstenstoßbau

n o o

s g

Der Firstenstoßbau kann bei steilstehenden Erzlagerstätten eingesetzt werden. Ausgehend von einer Wendelstrecke (Abbildung 8) wird im Rahmen der Vorrichtung zunächst eine Gangstrecke aufgefahren, die den Erzkörper in seiner gesamten Mächtigkeit unterfährt. Die Gangstrecke ist meist durch eine Schwebe, das heißt durch einen stehen gelassenen horizontalen Lagerstättenstreifen, von der Förderstrecke getrennt. Ausgehend von der Gangstrecke bzw. von der nächst höher gelegenen Sohle werden vertikale Rolllöcher für das Erz und den Versatz erstellt.

n o

l s n

i t a

Aus der Gangstrecke bzw. aus einem vorher erstellten Überbruch wird ein gerader Firstenstoß mit einer Höhe von bis zu 4 m aufgefahren. Dies geschieht mittels Bohr- und Sprengarbeit. Ist dieser Stoß abgebaut kann er versetzt werden und dient als Arbeitsebene für die Gewinnung des darüber liegenden Stoßes. So wird ein Stoß nach dem anderen angegriffen, bis die nächst höhere Sohle erreicht ist. Als Versatzarten kommen Spül-, Pump-, Sturz-, Blasoder Schleuderversatz in Betracht.

a r T

Eine Sonderform des Firstenstoßbaus ist der so genannte Magazinbau. Das Verfahren ist nur bei sehr standfestem Nebengestein und einer regelmäßigen Ausbildung der Lagerstätte anwendbar. Der Abbau funktioniert prinzipiell wie beim Firstenstoßbau, allerdings dient hier das bereits gesprengte Haufwerk als Arbeitsebene für den Angriff des nächsten Stoßes (Abbildung 9). Da das gesprengte

n i m

o c

Abb. 9: Magazinbau [2]

und damit aufgelockerte Gestein mehr Raum in Anspruch nimmt als das anstehende Gestein, muss ein Teil des Erzes durch Trichter auf die Fördersohle abgezogen werden. Es muss stets soviel Haufwerk abgezogen werden, dass ein ausreichend großer Arbeitsraum im Bereich des Firstenstoßes entsteht. Das Verfahren ist sehr leistungsfähig, allerdings ist ein großer Teil des verkaufsfähigen Wertminerals auf längere Zeit im Speicher gebunden. Zudem ist das Verfahren nicht anwendbar, wenn das Material, wie bei einigen sulfidischen Mineralen der Fall, zur Selbstentzündung neigt oder wenn eine Veränderung des Speichergutes beispielsweise durch Oxidation auftritt, die eine Aufbereitung möglicherweise erschwert.

Global Blast Borehole Technique

Surface and Underground Mining with an Outlook to Future Techniques and Mining Developments

Dipl.-Ing. Karl-Heinz Wennmohs Atlas Copco | Mining and Rock Excavation Technique | Essen | Germany

Blasting and drilling engineering has proven to be one of the most effective and safe loosening techniques in global surface and underground mining. However, it should be noted that this statement does not refer to mining operations with geological conditions that allow for application of economic, mechanical loosening techniques.

Blast Borehole Technique â&#x20AC;&#x201C; Underground The 30 kW impact performance limit for hydraulic drill hammers in underground small bore drilling (38 -64 mm) was considerably increased through the launching of a 40 kW hydraulic drill hammer during the 2012 Las Vegas exhibition. With todayâ&#x20AC;&#x2122;s drilling tool standards, such performance boosts are only possible through an increase of blow rate. The reasons are clear limits to the resilience of drilling tools, with regard to the maximum load through single impact energy. This new generation of hydraulic drill hammers with more than 100 Hz blow rate requires highest precision in control of the hammer mechanism and in production of the components.

Fig. 1: Development of Impact Performance in Hydraulic Drill Hammers

Issue 01 | 2013

Controlling such extraordinary high impact performance is only possible with a highly developed computer system, since reaction times for influence on drill parameters are extremely small, due to the high drilling speed. Furthermore, in relation to the progress of drilling, the drilling fluid has to be adapted to the conditions of the cuttings according to pressure and volume. This performance class is primarily applied to 2-4 armed drilling jumbos, which are operated according to requirement profiles of automatic operations for mechanical pre-drilling and injection drilling of up to approximately 30 m. This drilling technique status in hydraulic drilling hammers for small bore drilling will remain for a few years, but further developments can be expected.

Up to now, this design size of drill jumbos has been designated for classical tunnel driving. However, with the extension of mines and the increase in diameters, twoand three-armed drill jumbos are increasingly being used in excavations. Typical examples are tunnels and drifts for the underground excavation in the Chuquicamata mine, north of Chile.

Fig. 3: Drilling equipment for underground extraction drilling

In the year 2000, with high-performance hydraulic drill hammers with 40 kW impact energy, the production drilling equipment developments for underground long hole drilling were already advanced. Compared to drill hammers for small bore drilling, this drill hammer class has completely different impact characteristics. In these applications, considerably bigger and stronger drill rods are applied in connection with other borehole diameters (76 -140 mm). These drill hammers have substantially higher single impact energy, and the impact frequency is considerably lower. It is for this reason that the dimensions and weight of the main piston are basically larger. Such are important drilling parameters for long hole drilling. Apart from classical top-drill hammers, down-thehole hammers are increasingly being used in large-scale operations. The reason is bigger bore hole diameters and the comparatively long boreholes. It is possible that there are limits for the transfer of impact energy for the top hammer drilling with these conditions.

TRANSFER OF TECHNOLOGY Fig. 4: Extraction drilling device with water-driven down-the-hole hammers

These down the hole hammers are operated with compressed air or water. In compressed air application, high-performance compressors are used, which increase the available air chucking from 5 bar to 20 -25 bar. In order to reduce the dust generation, these devices are operated with an air-water mix. In terms of energy efficiency, water-operated down-the-hole hammers are powerful

and much more economical than if they are operated with pressurized air,. However, the operation with water requires an underground infrastructure, which allows for such volumes and quality of water. A typical utilization of this technique can be seen in the LKAB in north Sweden Kiruna.

TRANSFER OF TECHNOLOGY Modern long-hole drilling devices for underground extraction offer all possibilities for control and can generate a complete wheel of bore holes, up to a borehole length of 50m, either fully automatic or through remote control. Since, according to the rocks to be drilled, such borehole lengths call for a change of drill bits, these devices with top drill hammers offer the possibility of automatic drill bit change. The drill bit magazine on the drilling device makes this possible. This magazine can carry 9 drill bits with a diameter of 115 mm. Based on the parameters given, a modern drilling device control selects the time of changing the drill bit. This is critical for the drilling progress, but also an important step towards optimizing costs of drilling devices, since it prevents over-drilling of drill bits. In order to ensure that high-performance drilling devices can drill securely and appropriately, they have to be able to timely detect and react to irregularity in mountains, e.g cavities or areas with very soft formations. This technique ensures that, upon reaching such a zone, the drill hammers automatically are put into a reduced impact performance mode, and unnecessary empty strokes are avoided. After drilling through this zone, the system recognizes the situation, and the drilling device continues to work at full force.

Drilling borehole technique above ground The mining in open pit mines through loosening and crushing begins with modern drilling devices. In formations of over 100 MPa rock compression strength, these are devices with percussion drilling methods like top-drill hammers and down-the-hole hammers. Exceptions are open pit mines with borehole diameters between 180 mm and 406 mm. If the rock parameters of approx.. 80 – 200 MPa compression strength allow for it, rotational drilling methods with rotary bits are applied. In higher compression strengths, which can be above 300 MPa, modern down-the-hole hammers are applied. It should be noted that transition between rotary drilling technique with rotary bits and the percussion drilling is fluid and is dealt with differently. Large open pit mines with annual outputs of 60 -100 million tons possess modern drilling tools, which can often operate without extension drill rods in bench heights of up to 18 m. This drilling technique, which is internationally called “single pass drilling”, reveals high gross drilling outputs and allows for automations, if needed.

TRANSFER OF TECHNOLOGY Nowadays, drilling devices for diameters of 51 – 178 mm are the drills mostly used in quarries and they work with top- or down-the-hole hammers. The impact performance of top drill hammers in this machine sizes lies in a spectrum between 20 and 40 kW. Modern down-the-hole hammers of this class, with an operation pressure of 30 bar, have a comparable impact performance of 40 kW and above on the borehole bottom. Drilling devices in weight categories of up to 25 tons are used in open pit mines with an annual production of up to 10 million tons, or in large operations for special drilling tasks, which cannot be covered by large-scale drilling equipment. This so-called large-scale drilling equipment are design sizes with machine weights of up to 200 tons. This is understandable, since it is necessary to specify respective pressure values on the drill string, without changing the position of the drilling device. When applying rotary drilling technique, in which mostly rotary bits are applied, large amounts of cleaning air are needed to convey the cuttings from the borehole bottom to the borehole top with high speed. In order to do so, compressors are installed on these drilling devices. They have a delivery quantity of up to 105 m3/min, with an operation pressure of 7.5 bar. With this technical fitting the installed motor performance on the drilling devices is 1200 kW. This can be either a diesel engine or an electrical engine.

Example of a typical open pit mine in hard rock The Boddington open pit mine of the Newmont Company, in which gold and copper are mined, is located in west Australia, close to Perth. Its geology consists mainly of andesite and diorite, with a specific density of 2.8 tons/m3, and uniaxial compression strength of 250 MPa. In addition, there is dolerite with a specific density of 3.0 tons/ m³ and compression strength of > 300 MPa. These geological data naturally have influences the drilling engineering during mining. All drilling devices are equipped with rotating hammer drills, which mainly are down-the-hole hammers. Mining extends over two open pit mines, which are connected to each other. The bench height is 12 m, the borehole diameter for the extraction drilling boreholes is 216 mm. Smaller borehole diameters are only selected for border areas (slopes). The drilling pattern, which based on geological conditions, was developed in a way to produce a rock pile with smallest possible fragments, in order to use the cost benefits of blasting engineering, compared to crusher engineering.

In the areas where due to geology, rock strength and quartz content rotary drilling technique reaches economical limits, these drilling devices are used with down-the-hole hammers in diameters between 193 and 269 mm. For such applications the drills are equipped with high-pressure compressors with delivery quantities of up to 41 m3/min at 24 bar. The exhaust of the down-the-hole hammers is utilized as drilling air. The motors in these type series have 560 kW and are electric or diesel-powered. An important step in development of drilling engineering is the so-called PARD-Method. PARD stands for percussion assisted rotary drilling. This technique consists of a standard rotary drill bit, with a down-the-hole hammer, which strikes a socalled “soft” stroke on the drill bit with the low air pressure (7.5 bar) of the drill air. The combination of these systems presents astonishing results. The following results show an example. In an open pit mine in South America , with a rock compression strength of 200 – 250 MPa, borehole depth 16.5 m, boring time with rotary drilling approx.. 60 min/borehole. The combination of rotary drilling technique and down-the-hole hammer reduced the time by 50%.

The extraction from this operation is approximately 100 million tons per year. Currently 18 drills, including equipment of subcontractors, are operating around the clock. 100,000 meter drilled per month is needed for production. This can be achieved with a gross drilling performance of 22.5 meters drilled per hour for production drillings of 216 mm borehole diameter.

Approximately 1,000 km of drifts are needed for preparing the actual mining. An economic operation of such deposits with decreasing metal contents is only possible through conveying of large masses. The projections show a reduction of copper contents in the deposits. The positive characteristic of Chuquicamata is the share of molybdenum in raw ore.

The mining of approximately 100 million tons produces roughly 100 tons of gold and an interesting amount of copper (Source Newmont)

This mining method requires high investments in development and equipment. The under-cut and the production areas require a considerable number of drifts. In order to start mining in 2018, four production levels are excavated, which ensure mining of 340,000 tons of copper per year. Once the digging is completed and the block cave is in operation, mining costs are very low, as there is only loading and conveying. The classical drilling and blasting is only applied for crushing of large ore rocks at loading points, when mechanical bolder equipment fails.

Planned Large Mines The current situation in the commodity industry leads globally active mining companies to large investments in brownfield and greenfield projects. Therefore, extensive mining projects are being implemented or planned in mining regions. Examples are projects in Mongolia, project Oyu Tolgoi and in Chile. The open pit mine Chuquicamata in Chile is being developed into an underground mining. This open pit mine is currently the largest copper open pit mine in the world, with an annual production of approximately 440,000 tons copper per year. This means that this mass open pit mine will be converted into the worldâ&#x20AC;&#x2122;s largest underground mine ever operated. In the course of conversion the open pit mine is crossed underground with tunnels and drifts and consecutively operated as a typical mass mine with the block caving mining method.

Issue 01 | 2013

Mining is concentrated on a level stripping of the ore body at the numerous loading points, as well as on avoiding cavities within the mining area. The operating equipment is construed for a daily conveyance of 150,000 to 200,000 tons. Since such conveyance can hardly be done vertically, it is done by belt conveyance. The excavations have started in 2012. Various internationally renowned companies conduct the excavations for ventilation-, transport- and access tunnels and the underground exploratory work of the open pit mine. This work is planned to be completed within the next years, until the start operation is taken up, and the underground mining is to start in 2018.

Fig. 9: Developed mining with bock caving

Outlook Future mining operations, which are developed from open pit mines or as “greenfield projects”, increasingly are planning their work with the “bock caving” mining method, in order to achieve their high production goals. However, this technique presumes specific mountain parameters. In case these are not met, known mining methods are to be applied, which can be modified based on the available machine- and blasting agent technique. In these large mines, automation possibilities should increasingly be used, particularly in the areas of drilling engineering and conveyance. This includes involvement of the entire equipment in a computer network, which allows for remote control and access to equipment functions in case of interruptions. The connection can help to use recorded data of the drillings, as well as borehole position and length for consecutive blasting. The search for suitable personnel is more and more becoming a key issue for mining companies. Jobs in mining have to offer more than financial incentives, they have to be attractive and to attract the future generation. Among these attractions are trainings with simulators (drilling, loading, conveying).

Issue 01 | 2013

Automation is the key in open pit and underground mining. The rationale for this need lies in the abovementioned problem, which is finding personnel for open pit and underground mining. But another key argument is the possibility of a higher utilization of machines. The matching of drilling and blasting engineering with the goal of optimal fragmentation of the excavated material will have a central position in the cost-structure of mining. Therefore more interaction of drilling and blasting engineering is needed in the future. There is a high potential for development in the overall area of mining. In medium-term, mechanical loosening techniques will be a serious competitor for drilling and blasting engineering. This is not only due to safety issues with regard to handling explosives, but also due to the discontinuous operation of drilling and blasting engineering. Currently there are extensive global efforts to develop a continuous cycle in the advance technique, through the application of new methods in mechanical loosening technique.

TRANSFER OF TECHNOLOGY Fig. 10: Networking of Equipment

These new technologies will be applicable to all geologies encountered. It could be a possible solution, particularly in mining in extreme depths of 5,000 m and above, as the dangerous and difficult working conditions in these depths pose great challenges due to the increase in rock bursts. In the coming years the available drilling technique for open pit and underground mines, combined with blasting means, will not loose much of its market shares. Mechanical loosening techniques with all their advantages in operation will have to prove cost-effective. This is exactly why there is a potential for advancements in modern drilling and blasting engineering in future years.

Liquid oxygen explosive

development and application

by Dr. rer. nat. C. Becker | Dr.-Ing. B. Schwark-Werwach | Institute for New Basic-Technologies (INBT) | Nordhausen | Germany

During the 17th BUS- Congress, the two authors of this paper have made two separate presentations on the characteristics (1) of the PMMA-LOX-Ex system and the resulting automated applications with regard to blasting (2). During the past two years many new studies have been conducted on the PMMA-LOX-Ex system, as well as studies on further applications of the system in various areas of blasting , such as special blasting and extraction blasting.

In summary, these are: 1. Operation of blasting equipment that allows for being furnished with up to 25 kg of LOX-Ex 2. Determining further blasting parameters and outputs of the PMMA-LOX-Ex system. 3. Implementing various simulated blastings. 4. a) Plating and b) impacting of conventionally nonweldable metals through blasting. 5. Successful multiple shelling with LOX-Ex-capsules on gypsum and greywacke rocks, according to the LOX-Exmethod (2) introduced in 2011. 6. First successful test on the basis of the Imloch-blasthole method. 7. First successful developments and testing of LOX-Exfuses.

Operating blasting equipment of up to 25 kg LOX-Ex This is manually operated equipment that pre-cools fuel and containers of explosives and doses initial amounts, mixes and stores them in Thermo- storage boxes. The centrepiece is the pre-cooler for the molecularly structured nano-particle-fuel, seen in fig 1. The central cylindrical space, which is equipped with a mixing shaft, serves for the collection of fuel. It is enclosed by a double-walled barrel, which is filled with the cooling medium, that is liquid nitrogen or oxygen. After 1.5 to 4 hours - based on the amount of cooling liquid and intensity of stirring- the fuel is cooled to a temperature of approximately 160째C, which is sufficient for a dust-free mixture.

The INBT would like to thank the following companies and institutes for their support and collaboration in reaching these development milestones: BAUER Maschinen GmbH, Perforator GmbH, Knauf German Gypsum Works KG, ISAF TU Clausthal, KANEKA Corporation, SFL Water Power Plants GmbH and the BAM.

Further blasting parameters and outputs The LOX-Ex is a liquid oxygen- fuel system, in which the fine structure of the fuel is specifically used to influence parameters such as blasting speed. The composition of the explosive, the system PMMA-LOX-Ex, can be adapted to respective tasks. As such it is possible to optimize the quality of the blasted rock. Following parameters can be “pre-set” in advance: a) Load intensity b) Speed of detonation from approx. 1000 m/s to over 9000 m/s c) Volume of fumes and d) Blasting dynamics or smashing power. On a): Like with all explosive agents, this is determined by simple specification of quantities, immediately before application. On b): NIn addition to patented methods, the granulation or compaction (specific cluster forming) of the molecularly structured nano-particle fuel is the determining factor for this target parameter. On c): the volume of fumes, which are generated during chemical reaction of the blasting agent, can be set by a dosage of LOX or by addition of water in appropriate physical modification. On d): The blasting dynamics of the explosive can be optimized through integration of chemically inert material and spacing or shaping elements at the load.

Many video documentations (6) of free blasting tests show that in the moment of chemical reaction the fire ball (reaction plasma) lights up well visibly and big in size, according to the energy content of approx. 9 MJ/kg. The view can only occasionally be obstructed by raised dust. Contrary to many conventional blasting agents that are construed to gas and fume generation, this reaction plasma that passes into the gas phase has its “own” extensive and short-term thermodynamic energy content. This potential can be extended for a few ms and shifted through addition of long-term fume generators, at the expense of the fireball power.

Conducting various simulated extraction blastings Three simulated extraction blastings were conducted in the years 2011 and 2012. The first two test were qualitative ones, and it was only the third test which aimed at a quantitative result regarding the break-off amount per each kg of explosive.

Test 1: Borehole blasting This test was conducted in a vertical borehole of a depth of 4m and a diameter of 90 mm, with a distance of approx. 3 m to the rock edge in the gypsum rock. An insertion slot consisting of PP is inserted over the entire borehole length. The upper meter of the inserted tube was designed in a way, that it could be removed after inserting the load. This tube was filled with 12 kg LOX-Ex (i.e. 4kg/m) from the borehole depth up to 1 m below the surface, and insulated on the top with snow and ice (since it was a winter day) and ignited with a commercially available instantaneous fuse. The result of the blasting left nothing to be desired.

Further parameters are: •

•

Smallest column charge tested in 2011 was 14 mm. In the upscaled comparison of tested column charges of 70 mm no losses in break-off amounts and quality of blasted rock could be seen. Tests have shown that, based on rock type, 85 to 100 g PMMA-LOX-Ex, applied with insultation, break off approximately 1 ton of rocks. In case both components of the PMMA-LOX-Ex (i.e the PMMA fuel and liquid oxygen) are applied in pure form and in correct relation of composition, no toxic nitrogen oxides occur, only H2O and CO2.

Issue 01 | 2013

Test 2: Mini blasting The aim of the test was, •

To check whether charge columns with very small diameters entail output losses

•

And to determine, how the blasting performance and grain composition changes with the design size, as well as to develop a basic concept of the automated and low-vibration continuous extraction blastings with regard to feasibility.

TRANSFER OF TECHNOLOGY 6 Boreholes of 28 cm depth and 20 mm in diameter were drilled into the anhydride soil in two lines and with a distance of 45 to 50 cm, vertical to a brim. PE tubes with an internal diameter of 14 mm were inserted into the boreholes, which were each filled with approx. 38 g PMMA-LOX-Ex, furnished with an electrical detonating cap, insulated and ignited. The holes directly facing the brim were furnished with instantaneous fuses and the second row was furnished with fuses with 25 ms delay. Due to some mishaps during precooling of the insertion slots and fuses it was only possible to fill and ignite 4 遜 holes instead of 6. In addition the terrace was neatly blasted off and it was proven that charge columns with diameters of 14 mm can ignite and blast without output losses.

Impacting Contrary to plating, where metal parts are “rolled into each other“ through blasting, the goal of impacting is to explosively connect small-area and conventionally unweldable metals through direct exposing and higher speed. During the tests a Cu-, as well as an AI plate with thicknesses of 3 mm and 50 mm square were flatly exposed on a construction steel plate with measures of 20 mm thickness and 100 mm square, through 300g LOX-EX. Picture 7 shows the impacted plates immediately after the test. In the upper part of picture 8 micro-sections over the inter-metallic interface of AI and in the lower part the one of the CU steel bonding is shown.

Based on the chosen experiment setting and the data of explosives, the estimation method according to De Carli and Meyers for speed of flyr plate (3) resulted in impact velocities of approx. 2600 m/s for the CU plate and 4400 m/s for the AI plate. Under the same conditions, in case of usage of C4 in place of PMMA-LOX-Ex, the Cu plate would have impacted the steel with 2200 m/s and the aluminium plate with 3400 m/s.

Serial shots of LOX-Ex capsules on gypsum and greywacke rocks In 2011 and 2012, further technical developments were done and extended tests were conducted on the drilling and blasting method, also called LOX-Ex-Method (2). Hereby special, simply constructed PET capsules were filled with LOX-Ex and shot on gypsum- and greywacke rocks, as well as on a quarry rock face.

After three more shots bigger rock segments started to break out. These tests with the LOX-EX-method already show that with PMMA-LOX-EX the excavation performance is twice as much as with the method that is run with C4 and which was developed in the 1970ies by Loui and the AAI Corporation (4).

First test according to the Imloch blasting method The Imloch- drillblast method (named according to the Imlochhammer- drill method) is a special application form of the LOX-EX-method. The difference is, that a sack borehole is installed in the rock with a drilling machine, in which a LOX-Ex load is shot. See scheme of picture 13. In the first test of the method, the loop â&#x20AC;&#x153;drilling- shooting inâ&#x20AC;? was passed through three times. The drillings were done with a hand drill and were therefore not ideal with regard to their diameter quality and depth (manually only 10 to 15 cm per drilling could be achieved)

In case drillings are set accurately and by machine, specific rock break-offs of more than 400 kg per 100 g of LOX-Ex can be expected, independent of the rock type. This method can also be applied in an automatized way and possibly in combination with adits and tunnel boring machines. This is particularly possible in case mechanical and rock-breaking tools fail in particular rock formations. An advantage is, that with PMMALOX-Ex , no poisonous gases are generated and the dust can be removed by normal ventilation.

Initial Developments and tests of “LOX-EX-fuses” Lox-EX explosive can be ignited safely and reliably with commercial electrical detonators. Why use LOX-EX fuses? •

In case small portions of LOX-EX loads are brought to reaction in an automated way, a classical electrical detonator would boost costs per ignition of load.

•

Tests have shown (WIWEB 2008) that in case of igniting LOX-EX-loads with EL detonators, the detonation speed increases to the final speed after a distance of 2 to 3 cm. This distance is too much if geometrically small loads are used.

TRANSFER OF TECHNOLOGY •

Electrical cables are inexpedient during firing of capsules

•

During impact- welding tests it has proven beneficial, if the detonation speed is accelerated from almost zero to full speed, in order to keep the amount of explosives low.

•

LOX-Ex- fuses only become explosive in contact with liquid oxygen.

The fuses or detonation accelerators used up to now have been selected from the field of corruscatedexplosives (5), i.e non-gas producing explosives. This type of “LOX-Ex” fuses are currently applied to •

The LOX-Ex-Method

The booster-ignition of impacting and compacting tests and

•

The pneumatic, remotely controlled ignition of LOX-Ex loads.

Picture 15 shows two examples of utilization of such fuses. On the left a “naked” heat shell capsule for the LOX-Ex method can be seen. A hard gelatine capsule is under the tip of the liner, which contains an appropriate coruscate. In the moment of collision the coruscate in the LOX-Ex ignites and immediately causes acceleration of detonation speed to the maximum value. This happens even before the proper motion of the capsule in collision damages the geometry. In the right part of the picture there is a tiny booster load at the tip of the electro- detonator (black arrow). This load is activated through the fuse and acts as “detonation accelerator”, so that a successful impact-welding of small objects becomes possible with relatively small LOX-Ex loads.

Tough going for man and machine by Tilo Jautze | Veit Passmann | Mario Schöniger Thyssen Schachtbau GmbH | Germany

Fig. 1: Raise boring HG250 while drilling

n July 2008 RAG issued a call for tenders for the sinking of a new staple shaft at West colliery. The bidding consortium ‘ventilation borehole F275’ – comprising partners Thyssen Schachtbau GmbH and DHSS GmbH – has tendered successfully for RAG vertical development projects for a number of years and the client also entrusted this challenging engineering project to the experience and know-how of the F275 consortium.

Technical background Ventilation borehole F275 was constructed by raise boring to a diameter of 3.66 m and a depth of 320 m. Its completion meant a new ventilation route to the two proposed new working panels 630 and 632 in the deeplying Girondelle seam. Given the existing shaft parameters it was decided to use a Wirth type HG 250 raise boring machine for sinking the staple shaft. In order to achieve the directional accuracy specified by the client a Micron self-adjusting rotary vertical drilling system (RVDS) was employed in conjunction with a 10 „ drill string for the 12 ¼ „ directional borehole. After the pilot hole had been drilled to completion the directional drilling system with its roller bits was replaced by a Sandvik 3.66 m-wide raise boring head fitted with 20 monobloc disc cutters.

Issue 01 | 2013

Raise boring: Raise boring is a technique for drilling largediameter boreholes in solid rock. Raising means using a dry drilling process whereby an extension drilling head fitted with discs gradually cuts its way to the surface. The largest raise boring machines currently in operation can draw up to 1,500 tonnes. This class of machine can drill shafts more than 6.0 m in diameter and up to 1,000 m in depth – depending on the strength of the local rock strata. One of the prerequisites of the raise boring method is to have access at the bottom end of the hole in order to clear away the debris produced as the machine cuts its way upwards.

www.advanced-mining.com

TRANSFER OF TECHNOLOGY Pilot drilling The assembly and equipping work began at West colliery in November 2008, though the pilot drilling did not commence until 21.01.2009 due to a delay in completing drivage E550 for the bottom roadway. This lower road was to be widened to create a chamber that would constitute the end-point for the staple shaft with its shaft bottom. The pilot hole had to break through as accurately as possible to the centre point of this chamber. In order to achieve this level of directional accuracy it was decided to use a self-adjusting vertical drilling system, which is capable of a drilling precision of up to 0.3% deviation from the vertical. The pilot hole was drilled using a rotary, direct flush boring technique (direct circulation method) and the drill mud â&#x20AC;&#x201C; in this case clean water â&#x20AC;&#x201C; was fed to the drilling unit by means of a twin piston pump. The drilling operation started off smoothly and after seven days the pilot hole broke through to the chamber. The deviation from vertical was about 15 cm. The RVDS did not have to be changed over and completed the entire 320 m without a hitch.

The entire drill string was then removed and the RVDS with its drill bits dismantled. The drill string was then reassembled and connected to the raise boring head so that the raise boring machine with its connecting rod could be set up in the shaft bottom chamber. Once this assembly work had been completed the chamber was sealed off with a baffle wall, for safety reasons, so that the drilling debris falling down the raise hole would not pose a risk to men and machinery. A small opening was left in the right side of this screen to provide access for a chain conveyor that would gather up the material as it came piling over the top of the debris heap and transport it directly to the main belt installation.

Hole widening All the preparatory work was completed by 11.02.2009 and the raise boring phase could begin. Unfortunately the drilling team realised after just a few metres that the geological conditions were far from ideal for a raise boring operation. During the first 30 m there were major rock collapses that prevented the drilling head from cutting uniformly and steadily. Add to this the fact that these large blocks of rock, some of which measured up to 0.5 mÂł in size, occasionally caused damage to the drill head, which then had to be repaired.

TRANSFER OF TECHNOLOGY After discussions with Sandvik it was decided that the raise boring head should have its cutter arms and disc cutters strengthened so that the normal drilling performance could be achieved even under such difficult conditions. Some of the drilling parameters, including contact pressure and rotational speed, were also adjusted to meet the challenge. As soon as these measures had been implemented the boring operation was able to continue at a quite acceptable rate of advance. The extremely large-sized debris also posed loading problems at the foot of the shaft: the larger blocks sometimes jammed the chain conveyor and transfer point to the belt installation and had to be reduced in size. This meant frequent belt stoppages, which had a major impact on the drilling work and resulted in significant delays. The enormous mechanical stress imposed on the drill head, combined with the frequent changes in the geological make-up of the strata – harder rock alternating with soft to very soft ground – also meant that the drill head had to be repeatedly inspected and cleaned. The entire hole widening operation lasted until 04.06.2009. Despite the delays imposed by the poor geomechanical conditions the operation was completed within the planned time frame thanks to the introduction of week-end working shifts.

Shaft support After the drilling operation had been completed on schedule the shaft support phase was able to commence as planned in June 2009. RAG also commissioned the F275 consortium to carry out this part of the overall project. The infrastructure required to complete the support work was set up around the top of the shaft opening. This comprised a rope pulley frame, a platform winch, two hoisting winches for men and materials, an emergency travel winch and a cablewire winch. The ventilation shaft was to be lined with a layer of shotcrete at least 5 cm thick to support the inner face of the shaft column and, additionally, to act as a levelling layer in those areas where breakouts had occurred. The frequent side-wall collapses encountered during the raise boring operations resulted in a much higher consumption of shotcrete than originally planned and formwork had to be installed in some sections before applying shotcrete to level off the larger cavities that had formed in the sides of the shaft. The shotcrete was delivered pneumatically

Issue 01 | 2013

Fig. 3: Working stage and rope pulley

via a drop pipe and a Schuerenberg concrete pump was used to dry spray the material into place. The material was supplied by the client in ‘big bags’. The shotcrete phase was followed-up by the installation of a three-piece yielding ring support system combined with a roll-mesh lining that was fixed directly to the shaft wall. The very cramped working conditions for the fitting and assembly team (shaft diameter 3.6 m) called for an extremely precise operating routine and perfectly coordinated logistics.

Pipework As soon as the shaft lining had been completed the operation then switched to the installation of some 15 inshaft pipe columns. This comprised two fully-supported GRP pipes plus a total of 13 tension-proof socket connections with their mounting points at the top of the shaft. Screw couplings were also used for various pipes that would supply the new working panels with water, gas, air and calcium chloride (CaCl2).

TRANSFER OF TECHNOLOGY The final phase The final piece of equipment to be installed was a small cage system that would be used for regular descents of the shaft in order, for example, to examine the condition of the pipes. This installation comprised a rope pulley frame, winch and travel cage. The cage itself ran on a tensionrope guidance system, with boarding and alighting points provided at the top and bottom of the shaft.

Conclusions Despite all the problems and unforeseen obstacles staple shaft F275 was finally delivered on time, and fully equipped, in March 2010. The completion of F275 signalled the go-ahead for the first panel in the Girondelle seam to be started up.

Analysis of transfer stations of belt conveyors with help of Discrete Element Method (DEM) in the mining industry

by Dr.-Ing. Andrey Minkin ContiTech Conveyor Belt Group | Mining Europe |Northeim | Germany

ntroduction: Steady growing demand on row materials in emergency markets boosts a development and improvement of bulk material equipment in mining industry. Belt conveyors and their elements remain most popular mining equipment due to its very high productivity. Transfer stations are widely used for belt conveyors, where a bulk material is transported over long distances and/or complex mine or nature terrains. In the mining industry heavy and hard bulk materials (e.g. crushed rock or similar) must be transported very often. In this case a carefully designed transfer station essentially contributes for a long life time of a conveyor belt. The behavior of a bulk material flow in a transfer station is very complex and cannot be described sufficiently by an analytical model. The analysis of alternative designs of a transfer station can be aided by using a numerical simulation based on the Discrete Element Method (DEM) before a transfer station is ever built. DEM was developed in the 70th of the twenty century by Cundall for geo- and rock mechanics and is widely used now for simulation of material handling equipment [1]. From many numerical methods the DEM-method is the most representative one to describe a complex dynamic behavior of the discrete and discontinuous processes, which is e.g. the transportation of bulk materials.

Table 1: Typical transfer station designs used in the mining industry

Transfer stations and feeding points remain one of the most important and challenging units of belt conveyor systems, because a poor designed transfer station may cause: •

Build-ups and plugs in transfer stations resulting in high downtime of production

•

Dust, noise and spillages around the conveyor system

•

Essential wear or destruction of a conveyor belt, transfer station elements and idlers

•

Belt misalignment due to not a central loading

TRANSFER OF TECHNOLOGY

Fig. 1: 3D simulation models of the transfer chute geometry

All types of the above mentioned transfer chutes have advantages and disadvantages and should be applied depending on bulk material properties, conveying parameters, site conditions etc. This article focuses on the Rock Box type.

Design consideration for two rock boxes One existing and one alternative transfer stations with a different geometry and position of the rock box were considered in the two simulations. The simulation models were generated on the base of the CAD drawings offered by one mining company. They are shown by Fig. 1. The models are named after the Existing Rock Box (ERB) and the Alternative Rock Box (ARB). The bulk material rock was simulated with the following particle size distribution: •

Approx. 40% of total mass: 110 mm < dK < 150 mm

•

Approx. 60% of total mass: 37 mm < dK < 74 mm

The simulation parameters were chosen after the analysis of the given rock sample. The following operational parameters were considered in the simulation models.

Results of DEM simulation Figure 2 shows the steady state situation of the material flow of the two transfer stations. Due to the narrower wide of the chute in the configuration ARB, the material builds up higher on the receiving belt. Regarding also the lower position of the rock box in this configuration hardly any accelerating distance for the down falling of particles can be recognised. The material which flows down the rock box is generally directed against the conveying direction of the receiving belt. Fig. 3 shows this even clearer via the vectors of the particle velocity. The steady state condition can be not only recognised by the observation of the material flow but also by the analysis of the acting forces on the rock box. Fig. 4 shows the forces due to the particle impact on the rock box in transport direction (x-direction). After a certain time nearly constant values of both forces are measured. Although the particles hit the “ARB”- rock box with a higher velocity, lower impact forces in x- direction could be measured. This is caused by the higher particle velocity component in z-direction due to the increased distance from the drum.

The forces on the rock box acting in gravity direction (z-direction) are mainly influenced by the weight of the stored bulk solid on the rock box. Fig. 5 shows that the “ARB” rock box is loaded with a smaller force in gravity direction. A measurement of the stored bulk solid mass in steady state condition results in a weight difference of 1030 kg between the two rock box designs. The reason for this is the much more narrow design of the “ARB” rock box.

>10m/s

But not only the forces on the rock box could be measured. Also the impact forces on the receiving belt were measured in the simulation. This allows a prediction of belt wear. Fig. 6 shows the measured belt impact forces of the both transfer stations. The transfer chute configuration “ARB” shows clearly less impact forces due to the lower distance of the rock box to the belt.

Conclusions The DEM simulation of two rock boxes showed that by means of the DEM superior design could be identified and the higher wear impact on a belt reduced at the design stage with less cost. Summarizing it can be mentioned, that DEM is a powerful tool, which can be used for the development, design and calculation of conveyors and their elements and for problem solving in conveyor technology.

Fine screen mats for BIVITEC- screening machines For many years, the special screening machine BIVITEC has been successfully operated to produce high quality crushing granulation. Several screen mats are applied for crushed sand screening or â&#x20AC;&#x153;crushed sand filler removalâ&#x20AC;?. Punching mats with mat thicknesses of 2 to 7 mm are used to produce the classical separating cuts 8mm, 5mm and 2 mm, with square or slotted perforations, based on the task.

www.advanced-mining.com

TRANSFER OF TECHNOLOGY lead frame

0,2 mm line-perforation

precision frame

80 µm quadratic perforation The so-called “filler removal” requires corresponding fine perforations. In the past, mostly longhole perforation mats with mat thicknesses of approximately 1 to 2 mm have been used. The corresponding width of the hole lies in areas between 0.8 and 0.2mm. Holes of sizes „0,5 mm x 5 mm“, „0,3 mm x 3 mm“ and „0,2 mm x 4 mm“ are often used. A relatively new development of Binder+Co is the BIVITEC precision tissue mat. Here, fine tissue cuts are inserted into a form of synthetic-basic frame. The respective fine tissue is characterized by exactly defined and systematically controlled, reproducible tissue characteristics, such as mesh size, thickness, tear resistance and dimension stability. The standard mesh sizes used for crushed sand filler removal are 315 µm, 210 µm, 177 µm and 105 µm. The finest BIVITEC precision tissue mat currently has a mesh size of 80 µm.

Approach to technical screening machine construction In order to optimally design the screening machine, usually “filler removal separating cut”” screening tests are conducted with a pilot plant screening machine. As a first step, the feeding rate is determined with the help of a computer programme that is programmed on the basis of a factor method. The testing machine has an effectively usable screening length of maximum 2.33 m and is adjustable

Issue 01 | 2013

in its inclination. In most cases a simple screening attempt through one time feeding of the screenings and sampling of the two production streams would not or would only approximately correspond to a large-scale screening. In order to optimally design the required screening surface area, the following path is taken: The required feeding amount of approximately 1 m³ bulk goods for each test series is fed into the screening feed hopper, located in the technical center of Binder+Co in Gleisdorf. The first part of the test is started, considering the calculated screening duration, and after reaching a continuous operation state, representative sampling from both screening products and charging material is started. Hereby the entire stream of material is temporarily captured with a sampling container. The collective samples obtained in this way are reduced by riffle splitters or rotary dividers for the consecutive sample analysis. The two product chutes lead the major amount of the screening products into the coarse- and fine material container. Similarly, the second phase of the test is conducted with the coarse material produced in the first phase of the test. Hereby the screening plant is operated with a reduced feeding rate, so that the duration of both sections is fairly equal. Based on the size of the task, it might be necessary to conduct a third or fourth test phase with the same duration. It is possible to simulate screen lengths in the area of 2.33 m to 9.33 m.

For clarification purposes it should be noted that the three screening machines numbered 1, 2 and 3, shown in figure 2 refer to the same screening machine, but to different test phases. This type of test not only ensures the simulation of needed large-scale screen lengths or dwell times, but also provides extensive data material (after analysis of subsamples) for an optimal screening machine dimensioning.

Case study Over the last years, more than 20 new BIVITEC screening machines were installed for crushed sand filler removal. Currently single-, double, triple and quadruple deck screening machines are in operation. In addition to the filler removal, the double-decker machines allow for the coarser separating cut of 2 mm with the upper deck, for example. The separating cuts of the two-and- half decker are 2 mm and 5 mm through the upper deck. The short tween deck offers an additional screening area for the separating cut 2 mm, and the lower deck is entirely used for filler removal. The three-decker is in application for three separating cuts, the four-decker for four separating cuts.

Issue 01 | 2013

The screening of crushed granite is briefly outlined as a case study. Approximately 65 t/h of pre-screened granite of a nominal grain size 0/3 mm are to be feed into a threedecker BIVITEC screening machine. Each screening deck has an effective width of 2.4 m and an effective length of 7 m, measured from the first to the last screen mat. In case of only one impulse, the entire nominal screening surface amounts to 50.4 m². The swing characteristic can be set separately for each screen deck, or changed retroactively, if needed. In order to achieve the separating cut 1 mm, perforating mats are inserted into the upper deck. On one hand the perforating mats of the tween deck protect the precision fabric of the lower deck, on the other hand they allow for an additional separating cut of nominally 0.3 mm. This is followed by four screening products. The two overflows of the tween and lower deck can be combined partly or totally, as required (see fig. 3 a). On one hand this allows to react to changes in the fed material, on the other hand it gives the opprotunity to produce end products with various grain compositions or various “filler contents”. Figure 3 b shows a special screening machine in the production hall at Binder+Co in Gleisdorf. The machine was delivered at the end of 2012 to South Germany and will be integrated into a plant to process crushed sand.

New development “Air-supported fine classification“ In its newest innovation, Binder+Co mineral engineering combines screen and air technique and offers major advantages for the filler removal of crushed sands: •

Space saving

•

More possibilities to change separation characteristics

•

Lower fine sand losses

•

Better end product qualities

This new development can be divided into two areas that are connected in series. As a core component, the first area contains dynamically charged separators that, similar to a screen mat of a BIVITEC screening machine, are constantly stretched and compressed. The crushed sand, which is to be filler removed, is conveyed downwards over the inclined separation plane, at the end of which the coarse material (filler removed crushed sand) flows over. There is no resonating dust removal pipe in screening machines at the machine covering. Instead, various air inlets can be inserted in the cover area. There is a new gas cyclone, either Fig. 4: Schematic diagram of the new development

Issue 01 | 2013

under the perforated separating elements, or inserted downstream. Fig 4 shows the sketch of a possible model of this development with horizontal cyclone. The fine material (“filler product”) is actually sucked through the separating elements with an exhaust device and then separated with the help of the gas cyclone. The particular shape of this cyclone is different from conventional cyclones in the sense that the crude gas inlet in the cyclone is slimmer and ranges over the entire cylindrical height, it has a continuous drawbar in the cyclone axis and the conic casing is shaped considerably shorter (see figure 5).

The separator system is characterized by a smaller “screening area”, by mats with small openings (e.g. 0.2 mm x 4 mm), as well as by high dynamics. This prevents clogging of the perforations despite the high air flow (or the respective under-pressure in the area of separating elements) and supports the detaching of adhering grains and “dissolving of agglomerates” during the transport of the coarse material over the separating elements.

TRANSFER OF TECHNOLOGY Initial comparative filler removal tests in the technical center of Binder+Co were conducted in late 2012. Crushed sand with a nominal grain size of 0/2 mm from a German limestone processing plant with a filler content of 22% served as feedstock. The filler content is defined as the mass fraction of the grain size category <63 µm in the sand product. During the analysis of the test data, a specific feed rate was defined, as the relation of feeding rate (t/h) to the available nominal screening surface (m2). In figure 6 the reciprocal value of this specific feeding rate is recorded on the x-coordinate. This reciprocal value specifies the amount of square meters of screening area per 1 t/h crushed sand feeding, which has been provided for the filler removal. The filler contents < 63 µm of the coarse material are recorded in percentage on the y-axis. The filler contents of the feeding material are assigned to the x-axis value zero. The more of screening area or separating area is made available per t/h feeding material, the lower is the corresponding filler content in the coarse material. Blue rhomb symbols were used to present the results of the classical screening filler removal tests, and a blue compensating curve was drawn to characterize the screening behaviour. Similarly, the red squares and the red curve show the air-supported classification with suction and gas cyclone. The initial summarizing statement is: Compared to the classic screening filler removal, the airsupport only requires half of the separating area for the same amount of filler content in the coarse material.

Mining specialist BBM Maschinenfabrik Meran presents roadheader at BAUMA 2013

Fig. 1: The BRH 130 is designed for high performance and low wear. The illustration shows the design for a salt mine (photograph: BBM)

he highly efficient BBM Group, based in the city of Mülheim an der Ruhr, has for decades been one of the leading and deeply rooted service partners of the German coal mining industry. BBM has also acquired an excellent reputation internationally. For nearly two years BBM has also been on the market with the firm BBM Maschinenfabrik Meran GmbH as a manufacturer of high-performance mining machines and supplies a wide range of technical equipment such as roadheaders, roof cutters and milling loaders. With the BRH 130, BBM Meran are presenting at BAUMA 2013 the revised version of a selective roadheader that has long proved its worth. True to BBM‘s slogan „Quality leads to Quantity“, the crawler-mounted BRH 130 equipped with a cross-cutting head displays all of the features to make it an efficient, safe and durable high-performance device when driving roadways and galleries , as well as during mining operations under the most adverse conditions. With the 160 kW of power installed for driving the cross-cutting head, it can cut minerals and rocks with a compressive strength of up to 100 MPa. During the cutting work, claws relieve the load on the crawler chassis and increase the stability. Intrusion cutting is also performed with the crawler chassis supported by the hydraulic, zeroplay 400 mm advance motion. This is a significant advantage compared to the fixation via the crawler chassis which has been standard practice so far.

Excellent equipment and optimum ergonomics The front shovel can be expanded in various ways. The loading system with scraper blades, which feed the excavated material to the central conveyor, is very robust. The central conveyor is equipped with a central chain

TRANSFER OF TECHNOLOGY and scrapers and optionally available as a double-chain conveyor. For the discharge a sufficiently large conveyor cross-section is available. The machine can be operated by radio remote control - with visualisation on a monitor being provided in the rear of the machine - or by a control unit with an electronic profile control system display and the required operating and monitoring equipment, which is arranged on the side of the machine. The operator‘s cab provides the machine operator with a good view of the working face. The driver‘s seat and the elements arranged around the driver‘s seat are designed according to ergonomic principles and thereby help the driver to work safely and without becoming tired. For the hydraulic supply of all drives there is a double pump unit installed.

High performance and low wear even under extreme conditions The cutting drive of the machine is equipped with a cross-cutting head. 160 kW of electrical drive power for the cross-cutting head. Rugged helical cutting gear for extreme loads. Loading system with robust scraper blades and cylinder drive. Another advantage of the BRH 130 is the 400 mm displacement in the longitudinal direction of the cutting arm and centre support with slide. This allows the intrusion cutting to be performed from a stationary position while the roadheader rests on claws. Supporting the machine during cutting protects the chassis and above all the floor. All of this makes the BRH 130 an investment which is worthwhile because of the high efficiency levels, service life and low rate of wear. For the adaptation of the BRH 130 to different application requirements the following optional additional equipment is available: •

machine cover with integrated dust extraction channels

•

cooling system for high ambient temperatures

•

TRANSFER OF TECHNOLOGY

Thyssen Krupp:

n many mining areas, ore grades are declining. New mines are being developed in ever more remote areas. Pits are getting deeper and more hard-rock mines are switching to underground operations. This means that more material must be transported over longer distances, which creates new challenges. As mining volumes increase, demands for availability are also rising. As a result, conveying systems need to be equipped with modern drive systems that guarantee a high degree of reliability.

Gearless drive system, 2 x 3,800 kW, 63 rpm, 631 kNm

Partnership with Siemens for large conveying systems

Gearless drive characteristics and advantages

For many years ThyssenKrupp and Siemens have partnered to help build some of the most impressive conveyor systems in the mining industry. One of the greatest success stories is the Los Pelambres downhill conveyor in Chile, installed in 1999, which is the highest tension conveyor belt in the world. It transports copper ore over a distance of 12.7 kilometers from 3,200 meters above sea level down to 1,600 meters and in so doing generates up to 17 MW of electrical energy, which is fed into the grid.

Gearless drives are an attractive alternative for conveyors with higher power requirements. Due to their simple construction, such drives offer very high availability, robustness, reduced operating and maintenance costs, and reduced noise as well as the benefits of a variable-speed drive.

Technical limits of conventional drive systems The gear reducers traditionally used to drive conveyors reach their physical limits in demanding applications, such as steep-angle or high-capacity installations. For example, a modern conveyor system with a total drive power demand of â&#x2030;Ľ 20,000 kW requires at least eight traditional gear reducer drives, each equipped with 2,500 kW motors.

With gearless drive systems, a slow-running synchronous motor is directly connected to the shaft of the drive pulley. Because of the slow motor speed, no gear reducer is required. The rotor of the synchronous motor / Fig. 1 / is flanged onto the pulley shaft. Gearless drive technology is nothing new to the mining business. Mining companies have been installing high power gearless drives for mine hoists, excavators, draglines, pumps and mill applications for many years. While the technology is similar, the requirements differ for conveyor applications. Similar to mills, conveyors require a lot of torque during startup, especially in uphill applications. Gearless drives increase operating efficiency while at the same time providing high reliability and low maintenance requirements:

The traditional gear reducer solution has the disadvantage of reduced overall availability associated with the large number of mechanical components (e.g. more than 70 bearings for eight 2,500 kW gearboxes) which results in a lower mean time between failures (MTBF).

Issue 01 | 2013

www.advanced-mining.com

TRANSFER OF TECHNOLOGY Fig. 1: Gearless drive rotor during shop inspection at Siemens

For the previous 20,000 kW example, a gearless drive solution can be accomplished with only 3 or 4 low speed motors and no bearings or couplings. With fewer components, the drive station and electrical building require a smaller footprint / Fig. 2 /. This is especially beneficial for underground applications where the number of expensive excavations for drive stations is minimized. For downhill operation, the drives are able to work in regenerative mode and supply the mine operation with additional electrical energy. Advances in conveyor belt technology are also supporting the capabilities offered by gearless drive systems. Newly developed stronger

belts (ST-10000) are now available that can withstand the higher stresses resulting from increased drive power requirements. Mining companies are striving to reduce energy consumption and CO2 emissions and increase system reliability. Gearless drives meet these requirements by significantly reducing the number of mechanical components, such as gears, bearings and couplings, while delivering higher efficiency / Fig. 3 /. The capital expenditure for a gearless drive conveyor is equal to or less than that for conventional geared drives, especially if capital spare parts are a consideration.

TRANSFER OF TECHNOLOGY Fig. 3: Comparison of standard vs. gearless drive solution

First reference for gearless drives in German coal mine In 1985, O&K (now part of ThyssenKrupp) and Siemens installed the first gearless directdrive belt conveyor with cycloconverterfed synchronous motors. Engineers at RAG Deutsche Steinkohle were impressed by the converter technology and decided to use it in the underground Prosper-Haniel coal mine in Germany / Fig. 4 /. More than a quarter century later, the belt drives are still in operation – to the complete satisfaction of the mine. The conveyor system provides an availability of more than 99%.

Managers at RAG indicate that: •

There have been no significant interruptions or failures attributable to motors and converters.

•

Maintenance costs are significantly lower than for conveyor drives with gearboxes.

•

Estimated electrical energy savings of 10% are achieved annually compared to fixed-speed geardriven drive arrangements.

New gearless drive system for client in Peru Continuing their successful teamwork, ThyssenKrupp Robins and Siemens are now delivering an overland conveyor to Xstrata Copper’s new Antapaccay mine in Peru with a gearless drive system / Fig. 5 /. The conveyor system will transport ore over a distance of some 6.5 kilometers from the mine to the processing plant on a 1,370 mm wide belt travelling at 6.2 meters/second.

TRANSFER OF TECHNOLOGY

When the belt conveyer system is commissioned in 2012, it will be capable of transporting up to 5,260 tons of copper ore per hour. The drive system comprises two lowspeed synchronous motors – each with a rated power output of 3,800 kW – and the associated cycloconverters, motor cooling systems, converter transformers and complete electrical house for the drive station. A closed loop control system improves load sharing between the two motors.

Summary Long conveyors with large throughputs and/or high lifts require a significant amount of power. When the demand for power exceeds 3 MW per pulley, gearless drives for the conveyor become the preferred solution. Gearless drive solutions provide many benefits compared to gearreducer drive systems: •

Higher plant availability by eliminating electrical components, couplings, bearings and gearboxes – therefore minimizing the risk of downtime;

•

Up to 4% higher energy efficiency achievable with gearless direct-drive technology;

•

Longer conveyors with fewer drive stations and smaller footprints resulting in less excavation for underground applications;

•

Higher available power at the pulley;

Issue 01 | 2013

Fig. 5: Rendering of a drive station for the Xstrata Copper Antapaccay mine in Peru

•

Reduced maintenance achieved by reducing the potential for mechanical breakdowns through the use of robust components;

•

Fewer spare parts resulting in lower inventories and lower investment costs;

•

Reduction in noise levels achieved by eliminating the gear reducers, which are the noisiest component in a traditional drive system.

The mining industry, particularly in South America, is looking increasingly at large, high-capacity conveyors as a solution to meet ore and overburden transportation requirements. Gearless drive solutions have the potential to meet these new requirements efficiently and at lower operating costs.

Metso’s HRC™ takes

high pressure grinding roll technology

to the next level

etso’s latest development in comminution equipment, the HRC™, is a major step in the profitable application of high pressure grinding roll (HPGR) technology. Metso has made M several key innovations in order to increase throughput and decrease total cost of operation.

Patented Arch-frame eliminates downtime caused by skewing

Flanges maximize wear life and increase throughput

Metso’s patented Arch-frame creates an even gap setting across the width of the tires, limiting skewing that can result in downtime for mining operations. This antiskewing Arch-frame also prevents damage to the roller bearings (caused by misalignment) that can occur with the traditional HPGR design.

Used in place of spring-loaded cheek plates, the flanges keep the bed of material within the crushing zone and prevent material from bypassing the tires. This enables greater circuit capacity and increases the overall crushing efficiency.

Issue 01 | 2013

www.advanced-mining.com

NEWS & REPORTS In addition, by preventing material from bypassing the tires, even pressure across the width of the tire is better maintained. By distributing the pressure more evenly, the tire life is maximized by preventing a ”bath tub effect,” in which the center of the tire wears faster than the edges. Victoria Herman, Metso’s product manager for the HRC, notes that this breakthrough design is a response to the growing needs in the mining industry. “Energy efficiency has been attracting our customers to HPGR technology for years,” she says. “But (our design concept) increases capacity and crushing efficiency – and that’s something mining companies are always looking to improve on.”

Other notable benefits of the HRC™ •

Hydraulic cylinders are positioned to create a compact design while still providing excellent crushing strength

•

Dust enclosure minimizes dust and reduces noise

•

Transporter facilites a safe and fast tire replacement

•

Feed hopper include liners designed for long life

•

Studded tires maximize tire life by building up an autogenous layer

The HRC is ideal for high-tonnage, hard rock applications and can be used as a tertiary, quaternary or pebble crusher. Currently, several HRC units are in operation around the world – with a total of 6,500 operating hours including over 3,800 hours in a mining hard rock application.

One crusher, two configurations

Sandvikâ&#x20AC;&#x2122;s New Prisec TM CI5** Series HSI

he new generation of compact horizontal impact crushers (HSI) from Sandvik provides customers with a low capital cost solution, optimum performance and good cubical shape, whilst ensuring the lowest operating cost per ton for a wide range of materials and applications. The all new patented and highly modularized Sandvik CI5** Prisec TM crusher range, additionally combines the ability to configure one base crusher into either a Primary or a Secondary configuration, thereby making it adaptable to everchanging requirements. The new Horizontal Shaft Impactor (HSI) range of crushers from Sandvik Construction have been developed in response to customer demands, building on the rock solid foundation of the primary and secondary series they will replace. Spearheaded by the CI511, this new range of crushers establish Sandvik as market leaders in the design and development of HSI crushers that have been developed to deliver exceptional rates of productivity and efficiency. All crushers possess the ability to be configured into either a primary or secondary crusher operating mode and with this unique, exclusive to Sandvik, patented design, provides customers with unparalleled adaptability.

Issue 01 | 2013

Exceptional reduction ratios Sandvikâ&#x20AC;&#x2122;s revolutionary all new design of crushing chamber ensures even greater reduction ratios than have been previously obtainable. Furthermore the Prisec TM crusher is able to easily produce impressive reduction ratios through the use of two uniquely designed curtains, which have traditionally required a three curtain configuration crusher. As well as enhanced productivity, this means fewer wear parts and reduced maintenance.

www.advanced-mining.com

NEWS & REPORTS Energy efficient overload protection

Dealing with crusher blockages

DThe CI511 Prisec TM is equipped with an infinite hydraulic curtain adjustment combined with a brake positioning system which relieves pressure, and setting, when un-crushable objects enter the crusher. No hydraulic power is required during normal operation, thus saving on operating power and reducing total power consumption. Both first and second curtains are infinitely adjustable via the Sandvik’s patented adjustment / braking system which is located on the cross beams of the crusher. This system gives hydraulic adjustment of both curtains, via the standard supply electric hydraulic power pack.

Crusher blockages have always historically been a problem, especially when operating in a primary configuration. Removal of the blockage, with the combined downtime and health and safety risks encountered, are now eliminated with the Sandvik new generation Prisec TM crusher. Due to the exceptional features of the crushers no stopping of the crusher is necessary, with no operator intervention inside the crusher, no heavy lifting gear required, all resulting in maximum uptime and reduced health and safety problems.

Rotor and hammer design The rotor and hammers can be considered as the heart of the crusher; this is why those used on the CI5** Prisec TM range are both robust and efficient. Rotors have superior weight and design, essential for delivering the high inertia required for optimum crusher performance, thus ensuring stability and smooth operation during production. The unique “banana” shaped self-sharpening hammer design helps to keep the contact heads sharper during operation, resulting in more effective shearing of the incoming material, and hence improved production.

Issue 01 | 2013

NEWS & REPORTS Easy and Safe maintenance A unique key safety interlock system ensures safe maintenance of the crusher and prevents accidental opening of the crusher and inspection doors even in multiple installations. It also allows the ability to raise curtains during operation without stopping the crusher to clear blockages, and re-set automatically to operating setting. This maximizes uptime and reduces the need for heavy lifting gear and operator / maintenance intervention, thereby reducing further Health & Safety risks.

Maximum uptime, Maximum breakage Through the modularized nature of the Prisec TM range, wear parts can be turned for maximum life/ usage with the same size being used across the whole range of crushers. In addition, Sandvikâ&#x20AC;&#x2122;s world leading technology in the hammer and liner material composition provides options far surpassing old industry standard of manganese, resulting in even lower operating cost per ton and the ability to operate efficiently in a variety of materials, especially recycling applications.

New Alpha 330 drilling tool system signals a new era of rock tool economy through increased rod life, more accurate collaringâ&#x20AC;&#x2122;s and straighter blastholes

In order to match the increased energy output from modern high power rock drills now used in drilling and tunneling, Sandvik Construction is proud to launch the Alpha 330 drilling tool system. This advanced system has been developed with special features that control power and, most importantly, ensure that this power is transmitted into the rock as efficiently, accurately and economically as possible. In tests, in varying rock conditions, the new design has been proven to deliver a 30-80% increase in rod life, provide more accurate collaring and straighter blastholes, thereby delivering greater advancement, improved profile control, thus enabling projects to be completed more rapidly, as well as reducing the overall cost of drilling and tunneling.

Issue 01 | 2013

www.advanced-mining.com

NEWS & REPORTS The Sandvik Alpha 330 has been designed and dimensionally optimized to replace the R32 connections, which until now has been the dominant Ă&#x2DC; 45 mm system. A key development of this advanced new system sees the drill string rod / bit connection featuring an entirely new thread design. Furthermore the Alpha 330 possesses a shorter thread on the hexagonal rods in the tool system resulting in a rigid, integrated powerpack drill string, which possesses superior resistance to bending stresses, thereby securing perfect energy transfer. As part of the manufacturing process more steel has been used for higher fatigue strength, which further helps ensure exact collaring and straighter holes, as well as delivering a 30-80% increase in rod life.

Designed to boost productivity Essentially the Sandvik Alpha 330 system has been designed to increase customer productivity; it is able to accomplish this due to inherent benefits derived from the stronger and more rigid R33 thread, which possesses a significantly larger cross-section than R32, thereby making it proportionately stronger. Further improving rigidity, the Alpha 330 possesses a new guiding function located between the rod and bit-skirt immediately behind the thread. This means that the rod cross-section over the guide is now 36% larger (Alpha vs. R32) at the rear of the connection, greatly improving

Issue 01 | 2013

the rigidity of the joint. After the bit-skirt, the rod crosssection increases to Hex-35 quickly, and smoothly, ensuring that the sturdy thread is well guided inside the bit-skirt, offering higher precision in collaring â&#x20AC;&#x201C; even in complex rock formations and uneven surfaces.

Customer satisfaction The reported benefits customers have experienced from using the Sandvik Alpha 330 tool system in global tunneling projects has been staggering: rod life has been extended by at least 30%; as well longer shank adaptor and coupling life spans. These factors alone have seen a reduction in total drilling tool cost by 20%, with additional benefits including high rates of penetration, advanced precision in collaring, superior drilling accuracy, faster and easier uncoupling of bits, as well as reduced machine downtime. Furthermore, the hard wearing and productive features inherent to the Alpha 330 has enabled tunneling projects to be completed in less time.

www.advanced-mining.com

NEWS & REPORTS Summary of key features of the Alpha 330 • New Short thread design and hexagonal rods result in a rigid, integrated drill string optimized for 43-51 mm drilling. • The new short thread design offers increased precision in collaring. • A rigid drill string results in straighter holes, permitting optimum drilling patterns, better hole accuracy and higher rates of advance. • Exact collaring and straighter holes (essentials for productive drilling) are assured with less over-break and lower overall costs. • Less downtime of machinery resulting in better scheduling through optimal productivity.

The new Alpha 330 from Sandvik Construction is the latest addition to Sandvik’s world leading rock tools range of products that are aimed at enhancing customer’s productivity, and efficiency, whilst reducing the overall costs of drilling and tunneling.

Wirtgen: rounds out new generation of cold recyclers and soil stabilizers

Cold recycling and soil stabilization made easy. The new WR generation offers even greater output, high cost-efficiency and easy handling.

Maximum quality every time – the WR 240 already delivered this level of performance when it was introduced to the market in summer 2012 as the first representative of the new-generation cold recyclers and soil stabilizers. With the two, new WR 200 and WR 250 models, Wirtgen now rounds out this product segment in time for bauma 2013.

New standards in cold recycling and soil stabilization

A small compact machine (WR 200) meets a powerhouse (WR 250)

With the world’s largest line of recyclers and soil stabilizers, Wirtgen has the right solution for every application. For example, the WR 240 is considered to be an all-rounder for the heavy-duty stabilization of large areas of non-cohesive soil, and for the conservative cold recycling of damaged asphalt layers. A variety of new features make it a pioneer in terms of performance and cost-efficiency, and it has impressively demonstrated both of these in practical use in recent months, as the exclusively positive feedback from customers confirms. Despite its higher productivity, the WR 240 consumes significantly less fuel thanks to state-of-the-art engine management, and therefore considerably reduces costs for contractors. What is more, their machine operators praise the large, modern cabin, the all-around view it affords, the machine‘s improved manoeuvrability, its optimized ergonomic design and its intuitive operation.

Wirtgen is presenting the WR 200 at bauma 2013, a smaller version of the WR 240. It boasts nearly identical features for both cold recycling and soil stabilization. It shows off all its capabilities in these applications, specifically its maneuverability on small, tight construction sites. Furthermore, it requires no special transport permits and is therefore ideal for one-day jobs.

Issue 01 | 2013

The WR 250 is the most heavy-duty machine of the new WR generation. This powerhouse is designed for stabilizing heavy, swampy soils and comes into its own on recycling and pulverization jobs, where it turns roadways up to 25 cm thick into homogenous granulate. What is new is the option of also operating the milling drum from the cabin, making it possible to flexibly activate a number of milling drum speeds. The milling drum design tailored to the WR 250’s high output helps to achieve outstanding mix quality at a high feed rate.

NEWS & REPORTS The product range: Individually configurable standard machines Wirtgen offers three time-proven performance classes which can be configured variably to meet the needs of each project: the 2200 SM, the 2500 SM and the 4200 SM. Over two dozen cutting drum designs are available as standard and further designs can be developed and built for specific applications. Used in open-cast mining, road routing work, railway lines and tunnels, over 420 Wirtgen surface miners are currently in operation around the world. The machines can selectively extract valuable minerals, coal, limestone, gypsum, bauxite, phosphate or iron ore with a high degree of purity. Thanks to the continual expansion of the machines‘ range of applications, they can also be used for special applications in salt, granite, kimberlite or oil shale mining.

Surface mining sets standards – Also in terms of economy A pioneer of surface mining technology, Wirtgen GmbH has been developing the mechanical process since the 1980s and has established it as an alternative to conventional mining methods. Requiring no blasting, the process avoids ground vibrations, noise and dust, minimizing the environmental impact. Surface mining also increases safety in the mines.

Mining companies who opt for surface mining make immense cost savings, as the initial investment is not only considerably lower than for conventional methods – the production costs are reduced by up to 40 percent, too. What is more, they can also rely on Wirtgen‘s longstanding application experience. For instance, the mining experts are available to provide advice on site for the entire duration of a project – extending from the organization of the project logistics to service in the mine. After all, machine availability is crucial to success in the mining business, where machines are in operation 24/7. Local service bases and comprehensive services offer customers maximum reliability when planning the deployment of their machine fleets.

Kleemann crushers and screens The Wirtgen Group offers a wide range of jaw, impact and cone crushers as well as screens for processing mineral raw materials and recycling construction materials. Kleemann has been in the business of processing natural rock and recycling materials for over 150 years. Recycling materials and the chunks of rock obtained from drilling and blasting work in quarries are processed into defined grain sizes. These classified final granulations are used in road and building construction, being standard additives for concrete as well as for asphalt base, binder and surface courses.

One of the key features of the Wirtgen surface miner is its ability to load cut material directly onto trucks – like this 4200 SM. The height-adjustable conveyor can be swung 90 degrees to either side.

Bell celebrates:

The European Bell factory in Eisenach, Germany, is gearing up for the new E-series models.

10 years of German manufacturing at BAUMA 2013!

2013 will be a milestone year in the history of Bell Equipment‘s German manufacturing facility, which celebrates its 10-year anniversary and gears up for the production of the new Bell E-series generation of Articulated Dump Trucks (ADTs) later in the year. Following the company‘s recent announcement to re-enter the Americas, the world‘s largest ADT market, the factory will also increase its production to supply Bell ADTs to this strategic new market.

10 years of German manufacturing Comments Bell Equipment Group Chief Executive, Gary Bell: „Having started manufacturing in Germany 10 years ago we‘ve had a fair opportunity to assess the value of producing our trucks in Europe and going forward we believe that our decision to produce in Germany is still good and valid. We‘ve positioned the company well to leverage new opportunities and are looking forward to the exciting times that lie ahead. We are also satisfied with the quality of our product from this factory; it‘s produced to a high standard as expected from a German facility.“

Looking back Bell Equipment started construction on its German manufacturing facility at Eisenach at the beginning of 2003 and the first of its European-produced D-series Articulated Dump Trucks (ADTs) rolled of the production line in October that same year. Ten years later Bell Equipment has established itself as a strong, reliable ADT specialist in the construction industry and earthmoving sector. In addition the company has grown its local supplier database, showing its deep-rooted commitment to the European region.

The company took the decision to develop the German factory following the immense worldwide success of its D-series ADT. Recalls Bell: „ADT production at our South African factory was near capacity and developing a European assembly plant presented many benefits in terms of flexible production, short delivery distances, improved logistics, the guarantee of additional machines and the strategic positioning for future growth in Central and Eastern Europe. „During the initial phase the factory supplied product to North America, however, that was terminated in 2005 due to a new arrangement with our American partners. Prior to this the factory had reached its design volumes and was running with pleasing efficiency,“ he said. „While volumes have not been as great as expected in recent years, and the European market hasn‘t fully recovered from the 2008/2009 global recession, it has provided sufficient volume for the factory and given us the benefit of not having to ‚round trip‘ our product. This has enabled us to focus on localising some of our component manufacture to Germany as well as to build our markets in the region and grow our distribution footprint to provide better support.

The European factory was designed from the outset to assemble the varied Bell truck range – from the smaller trucks up to the flagship Bell B50D. After strict end-of-line checks the Bell trucks are delivered to Bell dealers and customers across the northern hemisphere. (Photos: Bell Equipment)

as the Canadian dealer and distributor of its range of ADTs. Said Bell: „We are excited to be able to return to these markets, ADTs are the backbone of our business and a product we specialise in and access to the American markets is key to our global plans. As such we have planned for a significant increase for North American volumes off a low base.” Meanwhile work to equip and convert the German factory for the manufacture of the full range of E-series ADTs started early in 2013. The E-series meets the next tier of engine emission requirements and features some of the most cutting edge ADT technology to build on the company‘s heritage as an ADT specialist. Concludes Bell: „2013 should be a exciting year for the company in terms of growing our presence in North and South America and launching our E-series ADT to the global market. At the factory research and development continues strongly and this year we begin testing our 60ton truck.“ Gary Bell, Bell Equipment Group CEO. (Photos: Bell Equipment)

„As volumes increase to Eastern Europe, in particular Russia, it is our intent to further improve local value add and improve the company‘s competitiveness in these markets,“ he added. Although the overall market outlook for 2013 is not positive, with a 5 to 10% drop in market sales forecast, Bell is hoping to maintain similar levels to 2012 and has planned for a 15% increase in European volumes. In addition the facility will re-launch the production of trucks for the North Americas following the appointment of Wajax Equipment

International market introduction:

E-Series takes ADTs into new era!

Bell Equipment‘s new E-series, represented at BAUMA 2013 by the B30E, is set to build on the company‘s strong heritage as an Articulated Dump Truck specialist. The new range offers latest developments in 6x6-technology, continuing to provide class leading power and weightratios, advanced engine and drivetrain characteristics. (Photos: Bell Equipment)

Previewed at last year’s Intermat show, the brand-new Bell B30E will take centre stage for Bell Equipment at BAUMA 2013 to start the market introduction of Bell Equipment’s evolutionary new E-Series ADT range (Hall B4, Stand 108). Following the modular performance class concept Bell launches its new 30-tonner together with the smaller Bell B25E, both incorporating latest developments in 6x6-technology. While continuing to provide class leading power and weightratios, advanced engine and drivetrain characteristics, both models set new standards in safety, driver comfort and truck management. The Bell B30E, on display at BAUMA 2013, showcases the improvements Bell Equipment‘s design engineers have made in the key areas of performance and fuel efficiency. They have also taken ADT functionality to new levels with customer-focused advancements and the highest level of automated machine protection. The all-new truck platform has been specifically engineered to handle future emissions requirements and take ADT innovation into the next era.

Issue 01 | 2013

Defining new standards on proven grounds Fuel burn can contribute more than 40% of the operating cost on a site and has, therefore, always been a major focus area for Bell Equipment, especially in reacting to international emission restrictions schemes. The latest generations of Bell D-series trucks introduced their “Blu@ dvantage” SCR-technology (Selective Catalytic Reduction ) as an industry leading standard in fuel-efficient emission

control, compliant to Tier4i and EU-IIIB. Whilst the E-series platform has been designed for upcoming legal requirements, first generations of the new B25E (210 kW/1 120 Nm) and B30E (240 kW/1 300 Nm) continue to use the proven Blu@dvantage engine configurations of their predecessors, but engine power and fuel consumption have been additionally optimized through event dependant software that controls retardation, cooling and charging of accumulators. Bell Equipment‘s D-series platform, particularly for its larger ADTs, has continuously emerged as the best in class during its long lifetime due largely to the company‘s

evolutionary approach to design. It should come as no surprise that Bell Equipment engineers have opted to carry this platform through to the smaller trucks in the new E-series range by changing the front suspension on the smaller E-series trucks to an A-frame layout. „We‘ve increased the suspension travel and the A-frame gives a more independent ride. In ride quality evaluations numerous operators have been unanimous in their approval and appreciation of the improvements achieved on the E-series,“ commented Tristan du Pisanie, Bell Equipment‘s B30E Project Manager. Additionally, wider tyres are offered as an option on the B30E, while importantly still keeping the machine width below 3m to allow for easy on-road transportation of the truck to job sites in Europe. In keeping with the practice of carrying through attributes from the larger Bell ADTs to the smaller trucks, the company has switched to Allison The Bell E-series sets new standards in safety, driver comfort and truck management. Taking the driver experience to a new level is the Isringhausen seat with a three point safety harness, designed to improve ride comfort and reduce whole body vibration with its own suspension and dampening system. On the dashboard a full colour screen and an automotive mouse interface has been introduced to control the sealed display unit, which features more detailed and user-friendly onboard diagnostics.

transmissions. Bell previously used Allison transmissions on the small C-series trucks and believes that the change offers improvement in performance due to greater efficiency. Importantly the change is in alignment with Bell Equipment‘s single family design concept.

Therefore the E-series cab has a full colour screen and an automotive mouse interface to control the sealed display unit. The Bell ADT is the first to offer this technology and the standard reversing camera can also been integrated into the colour screen display.

For improved safety and productivity the E-series has an automatically engaged Inter-axle Differential Lock (IDL) giving the vehicle full automatic traction control. A sensor on the inter-axle differential identifies when an axle loses traction and automatically engages the IDL function while the vehicle is still moving. „This feature is working so well that the diff lock button on the Sealed Switch Module (SSM) may soon become redundant,“ says du Pisanie. In addition the B30E and B25E ADTs both have limited slip differentials in each axle so the cross locking of wheels is achieved automatically without any interaction from the operator.

Bell opted for an Isringhausen seat, with its own suspension and dampening system, to improve ride comfort and reduce whole body vibration. The seat also has a three point safety harness which can be configured, as an additional safety feature, so that the truck‘s engine will only start once the seat harness is fastened. Heated seats are an option for colder climates.

Driver comfort = owner profit According to Tristan du Pisanie, the operator‘s experience has been a key focus area and various improvements to the cab and suspension performance have been made with this in mind. „We wanted to build on what we had achieved with our long-standing successful D-series by simplifying the interface and making the cab more ergonomic where possible. When we looked at how to improve the operator‘s experience we took into consideration the lifestyles of today‘s younger generation of operators. Smartphone technology is growing in popularity and we also wanted to build the familiarity of what happens in your car into what happens in our E-series trucks,“ explains du Pisanie.

Modern flowing lines, in keeping with the current styling trend on road vehicles, offer the operator unsurpassed levels of visibility while lights have been positioned higher up on the body where they will be less inclined to attract mud. Additionally all surface areas that could potentially come into contact with hazards on the job site now incorporate a rolled steel section for even higher durability. Safety systems and features, such as handrails and high visibility mirrors, have been styled into the project from the beginning so that the finished product is aesthetically pleasing and polished.

Advanced ADT Intelligence „A lot of thought and testing has gone into the E-series design and the engineering team has had detailed interactions with customers, operators and the Bell Sales Team,“ says du Pisanie. „As a result the onboard diagnostics

NEWS & REPORTS are more detailed and user friendly. The E-series truck can store up to 72 hours of machine operation and there are more proactive advance warnings for the hydraulic system. Another technological advancement is that a Bell Field Technician can plug the screen display onto his laptop and link with our Engineering team in Richards Bay so that they can see the screen display and see exactly what is going on with a truck anywhere in the world.“ In line with the improved diagnostics, Bell Equipment‘s satellite fleet monitoring system, Fleetm@tic is also undergoing a major facelift with a new web application focussing on mapping utility so that Fleetm@tic is available on all multi-media including tablets, smartphones and PCs. The geofencing feature is to be reconfigured to increase vehicle safety by facilitating geofencing in multiple zones based on speed limitations related to load, inclination and site conditions. An additional feature will be a map tracking utility giving per minute tracking data. Of course Bell Equipment‘s other ground-breaking innovations such as keyless ignition, HillAssist, Bin Tip Prevention, Auto Park Application (APA), standard Turbo Spin Protection and On-Board Weighing (OBW) are still standard on the E-series. OBW-Accuracy has been improved through the addition of an additional load cell to compensate for different loading styles.

Proven and tested concept Bell Equipment‘s Head of Engineering, Pieter Goosen says that the E-series has been in development for the past five years and has undergone stringent durability testing, having enlisted reputable independent national and international test facilities for additional verification. Development has followed a well-structured process that has included an unprecedented level of customer interaction, concept vehicles and numerous prototypes to ensure a strong, reliable product. Extensive testing formed part of the process and engineers used structural analysis and dynamic analysis along with a rigorous testing programme on some of the harshest mine sites in the world to ensure that the E-series is worthy of taking the Bell marque forward. „We are confident that with Bell Equipment‘s continuous development philosophy the E-series platform will take us well into the next decade to further strengthen our pedigree as the ADT specialist,“ he said.

BEll VersaTruck:

Full OEM solutions for niche markets Bell Equipment‘s ability to listen to the needs of its customers and successfully translate these needs into tailor made machine solutions has led to the introduction of a new product to the company‘s VersaTruck programme, namely a B30D 4x4 to be displayed on the Bell BAUMA stand (Hall B4, Stand 108). The company, which was built on the specialised machinery concept, is recognised as the Articulated Dump Truck specialist and takes versatility to a whole different level with its VersaTruck programme. Customers are able to choose from a number of Bell ADT permutations to best suit their application requirements. Included in Bell Equipment‘s extensive list of tailor made solutions are ejector trucks, fire trucks, water tankers, lube trucks, flat deck trucks, hooklift trucks, container trucks, concrete trucks, timber trucks, waste handlers, waste compactors and even an underground concrete mixer. Managing this programme is the Bell Application Equipment (BAE) division, a substantial team with years of experience, which is dedicated to the design, fabrication and assembly of the Bell niche products. Clinton Wissekerke heads up this team and tells us about the latest addition to the programme. The B30D 4x4 solution for earthmoving and quarrying applications, which will be on display at BAUMA 2013, has arisen from specific enquiries from the industry. Wissekerke said: „Over the past few years we‘ve worked on several 4x4 variations on our D-series platform including the B15D for light duty industrial

applications, the T302D Timber Haulers and now the B30D 4x4, which is particularly well suited for use in quarrying applications worldwide.“ Wissekerke explains the reason for the 4x4 ADT: „Providing the same payload and engine performance as our standard B30D, the 4x4 option offers a tighter turning circle and shorter dimensions compared to our traditional 6x6 ADT with their optimized offroad capability. It therefore suits customers needing improved manoeuvrability, but still needing the higher flexibility (weather independence, heavy terrain) of an articulated truck compared to rigid chassis alternatives on the market. These customers may also reduce tyre costs - a major portion of the operating cost of an ADT - simply through reduced tyre scuffing associated with the third axle.“ Adds Bell Equipment‘s Marketing Manager: ADTs, Llewellyn Roux: „Of course the VersaTrucks are able to offer the best in performance, safety, fuel efficiency and ease of operation of our standard ADT range. Similarly they also have all the latest innovations and features, among them onboard weighing, keyless ignition, HillAssist, Bin Tip Prevention, Auto Park Application (APA), standard Turbo Spin Protection and our satellite fleet management system Fleetm@tic.

omatsus 91-tonne capacity rigid dump truck will be on display at Bauma 2013. The HD785-7 offers K impressive engine power and brake retardation, as well as excellent fuel efficiency. Its powerful and efficient Komatsu SAA12V140E-3 engine delivers 1178 HP at 1900 rpm and provides great acceleration, low fuel consumption with a top speed of 65 km/h.

To optimise performance and fuel consumption, the engine is fitted with a variable horsepower control (VHPC). This system sets the maximum engine power to one of four levels to match the job being carried out and the working conditions. The operator chooses between power and economy mode, and the VHPC automatically detects whether the machine is loaded or unloaded. Consequently, the HD785-7 delivers excellent climbing ability when required and fuel consumption can be reduced. The HD785-7 has an advanced transmission that effectively harnesses the engine power, with 7 forward and 2 reverse gears. The transmission includes K-ATOMiCS, Komatsus electronically controlled clutch modulation system, which controls both the engine and transmission to optimise clutch engagement. Combined with a skipshift function that automatically matches the travel speed to the incline, this system ensures smooth gear shifting and responsive acceleration.

Volvo Penta at Bauma 2013:

A new, exciting Start/Stop function – and an update of the coming Tier 4 Final engine range

Volvo Penta: Volvo Penta highlights Tier 4 Final solution.

hen the doors to Bauma 2013 will open on 15 April, Volvo Penta is ready for an exciting follow-up of the new Tier 4 Final engine range and for displaying engine features like the Start/Stop function – the latest Volvo Penta innovation that will help operators to significantly reduce their fuel costs.

The story of the Tier 4 Final engines started in January, 2011, when Volvo Penta introduced its range of engines compliant with Tier 4 Interim/Stage 3B – all based on the Selective Catalytic Reduction (SCR) technology. They were well received by the market. But the off-road equipment industry were also well aware that within less than 3 years they had to go from the Interim stage to the Final stage – a substantial 80% reduction of the NOx – from 2.0 g/kWh to 0.4 g/kWh. They were also facing the additional challenge of re-designing their machines for installing new engines and after-treatment systems from their suppliers. Revolutionising.

David Hanngren, Manager Product Planning Industrial at Volvo Penta, explains: “With our new Tier 4 Final engine range, we will meet our customers’ primary objectives: no re-generation, limited installation challenges, continuous optimised fuel consumption and low operating costs. With as few and as simple changes as possible, we aim to make our customers’ job as easy as possible”, and adds: “This is probably the best EGR system in the world”. The “light” EGR system added to the engines has provided further emission reduction. It will, at the same time, help keep the SCR catalyst operating at an optimal temperature. By avoiding a costly Diesel Oxidation Catalyst (DOC), installation is greatly simplified.

Volvo Penta chose to keep it simple To meet the new, stringent emission requirements of Tier 4 Final, Volvo Penta soon found that the well-tested and well-proven SCR technology was superior. Apart from meeting all the new emission standards, it would make life easier for all the equipment manufacturers already employing this technology.

Issue 01 | 2013

A new, solid engine range The Volvo Penta Tier 4 Final engine range for off-road applications consists of five basic engines. Thanks to the SCR system it has been possible to meet the new emission standards with only a limited number of technical changes.

from long and costly downtimes in the long term, but also to tailor the agreement in accordance with specific conditions and requirements.

All the engines in the new range will be on display at Bauma 2013, 15–21 April, in Munich. They will also be ready for delivery in 2014 – but already today they are ready for the OEM’s drawing-boards.

Mining industry people attending Bauma will most certainly focus on Volvo Penta’s new range of engines approved for underground mining applications; nine Tier 2 engines and nine Tier 4i engines with outstanding ventilation rates.

More Volvo Penta news at Bauma

A fourth novelty is the Volvo Penta Oil Analysis – an easily performed analysis that will enable operators to increase the intervals between services from every 500 hours to every 1,000 hours – a massive improvement which will pay off already in the short term.

At Bauma, Volvo Penta will also introduce the new, automatic Start/Stop Function for industrial equipment. It turns off an idling engine after a pre-set time span, and when the driver activates any machine control the engine starts immediately and the work can continue. This Volvo Penta innovation will help operators to reduce their fuel costs with up to 5%! Volvo Penta will also launch the new Industrial Extended Coverage, IXC – a programme that allows operators and equipment manufacturers to not only guard themselves

NEWS & REPORTS Liebherr-International AG

World Premiere at the 2013 Bauma:

Liebherr TA 240 Articulated Dump Truck

ith its new TA 240 Litronic, Liebherr is using the 2013 Bauma trade fair to introduce another model in its articulated dump truck range. The successful launch of the 30-tonne TA 230 is now followed by a model in the 40-tonne category – Liebherr’s response to growing market demand for complete programmes from a single source for the loading and transport of various materials.

As with the TA 230 Litronic, the model designation includes the payload in metric tons. With a load capacity of 40 t and a dumper body volume of 27 m³ with rear flap the TA 240 has been ideally planned for the fast, costeffective transport of large volumes of bulk material. The dumper body is specially shaped to speed up discharge of the contents.

Powerful driveline, innovative retarder The three HD axles have been designed for strength and stability, and are the ideal basis for the exceptionally highperformance 6 x 6 driveline with automatic transmission, torque converter and converter lockup clutch. This new articulated dump truck is driven by a powerful Liebherr D 9508 V8 diesel engine with SCR system and a displacement of 16.2 litres. It complies with Stage IIIB / Tier 4i exhaust emission limits and has an output of 350 kW (476 hp). With this power available, the dump truck can reach speeds of up to 57 km/h on level surfaces. When reversing, maximum speed is limited electronically to 16 km/h.

Issue 01 | 2013

A high-performance retarder makes the vehicle safer and more convenient off-road, and also helps keep operating costs low. The retarder’s braking action can be continuously varied and the desired value preselected. This is a very useful option, for instance if the vehicle is regularly used on the same downhill route. As soon as the driver takes his foot off the accelerator pedal, the engine brake and retarder are activated – with no delay and with the braking effect previously selected. At the end of the downhill gradient the retarder shuts down automatically, but the previous braking level remains available when selected again. The wet-type oil-cooled multi-disc brakes are operated only when the TA 240 comes to a halt for loading and discharging or if an emergency brake application is needed. All maintenance and servicing work on the new TA 240 can be completed with minimum loss of time. The driver’s cab and the engine hood can be tilted electro-hydraulically for quick, safe access to all maintenance points.

NEWS & REPORTS Functional design, bold styling

Liebherr components for key technologies

The new Liebherr TA 240 dump truck catches the eye immediately with its striking design and the driver’s cab with its exceptionally large window area. The restyled, extremely spacious cab offers the driver maximum comfort and convenience, and complies with the ROPS/FOPS safety standard. Visibility is excellent through the large windows, so that the dump truck can be positioned quickly and safely for loading or discharge. The ergonomically designed, airsprung driver’s seat is standard equipment and can be adjusted individually to suit the driver’s size and weight.

As on many other Liebherr construction machines, key technical functions on the new TA 240 are performed by components developed and manufactured at various Liebherr competence centres.

The controls for the automatic transmission and retarder, and also the tipping control levers, are very responsive in operation, so that precision control of the dump truck presents no problems. Thanks to the well laid out, easily legible display unit with touch-screen function, an innovative Liebherr PME electronic component developed in-house, the driver can check the vehicle’s operating condition at any time without being distracted from the driving task. As an option, the display can show images from the standard Liebherr front- and rear-view cameras or details of current temperature, engine speed, air conditioning, daily operating hours, number of discharge movements or number of operating hours. A further feature contributing to comfort are the highquality spring-damper units on the front axle, which are rated to withstand the most arduous operating tasks. The level of ride quality that they provide also helps maintain the driver’s concentration during long, demanding work sessions.

Issue 01 | 2013

Liebherr’s reliable hydraulic cylinders, which have proved highly successful in tough construction-machinery operating conditions, are used to perform tipping and steering movements on the new articulated dump truck. Thanks to its powerful hydraulic dumper body actuating rams, the TA 240 can discharge its full load reliably in only 12 seconds and return to the lowered position within a further 8 seconds. Equally successful in ensuring directional stability and reliable steering in all circumstances, even when crossing very difficult terrain, are the steering rams; these too are developed and manufactured in-house by Liebherr Electrical and electronic items such as wiring harnesses, cameras, the touch-screen display, other controls and the central machinery control unit are also of Liebherr’s own manufacture.

Liebherr is exhibiting its large IIIB-generation Wheel Loaders at the 2013 Bauma

t the 2013 Bauma, Liebherr is presenting its new IIIB generation of large machines for the first time to users worldwide. These wheel loaders were first shown to a wider public at the Intermat in April 2012.

Higher performance, enhanced stability The L 550 and L 556 have a redesigned engine compartment with the diesel engine installed transversely. This gives them an even more compact layout, and makes all the principal maintenance points accessible from ground level. The engine output of the L 576 and L 580 models has been increased, and all the large newgeneration machines have an optimised tipping load limit that further improves productivity and stability. In addition to the Z-bar linkage for standard operating tasks, Liebherr supplies industrial lift arm. No other manufacturer offers both lift arm versions in every machine category at no extra cost. The geometry of the industrial lift arm has been specially chosen for high load moments and ample force in the

Issue 01 | 2013

upper lifting area. As a result, exceptionally heavy loads can be handled. The pattern of movement is parallel over the entire lifting range. The industrial lift has a hydraulic quick coupler as standard equipment.

LPE driveline boosts performance and economy For the IIIB generation, Liebherr continues to use hydrostatic drive concept together with another Liebherr development: Liebherr Power Efficiency (LPE). This is an electronic mapped-characteristic control system that increases the machineâ&#x20AC;&#x2122;s handling power and keeps fuel consumption to a minimum. Compared with other machines in similar size categories, the innovative driveline concept cuts fuel consumption by as much as 25%.

NEWS & REPORTS Less fuel is needed for the same performance, and tyre and brake wear are reduced. The LPE system influences engine management proactively: the machine’s software receives an electronic accelerator-pedal position signal and computes the most efficient way of carrying out the operator’s wishes. LPE optimises interaction of the driveline components in terms of swiftness and sensitive control of the machine. The new-generation diesel engines are now even more environmentally friendly, with many other improvements, too: precision common-rail fuel injection optimises the combustion process and reduces pollutant emissions. Exhaust emission control is by means of a diesel oxidating

catalytic converter combined with a diesel particulate filter. In most situations, this filter can be actively regenerated by burning off deposits during operation of the machine, and the task in hand continued without interruption.

Straightforward maintenance, ease of control Cleaning and servicing are easier than ever before on the new IIIB generation of wheel loaders. The operator can reach the maintenance points for the principal components from ground level. Cleaning and maintenance work has been reduced to a minimum: the radiator assembly is again installed directly behind the cab, where air with a low dust content can be drawn in. The operator will appreciate the functional efficient, ergonomically correct cab layout. The operator’s seat with horizontal side-to-side suspension, available as an optional extra helps reduce operator fatigue. New cab mounts have been developed to lower the level of noise and vibration inside the cab. As far as outside noise emissions (sound power levels) are concerned, Liebherr is traditionally among the leaders; its machines operate well below the permitted limits.

AT THE Bauma 2013: Liebherr exhibits

revised Design of Midsize Wheel Loaders

t the 2013 Bauma, visitors will have a first opportunity to see Liebherr’s redesigned midsize range of wheel loaders. The L 524, L 528, L 538 and L 542 conform with IIIB / Tier 4i emission standards. These “Allrounders” on the wheel loader scene have been further optimised in the efficiency and safety areas in particular. Their performance and stability, their engine output and the power hydraulic ratings are now higher. Throughout their product range, the tipping load limits have been raised and the structural steelwork reinforced to make the machines even stronger.

Many innovations for greater productivity The LIKUFIX hydraulic quick-change system that has proved so successful on Liebherr hydraulic excavators is now available for midsize Liebherr wheel loaders. Working attachments can be detached and attached in a matter of seconds, working directly from the wheel loader’s cab. The hydraulic lines are connected fully automatically in the same way, with no hydraulic fluid leakage.

Issue 01 | 2013

As in the past, the purchaser can choose at no extra cost between a Z-bar linkage for standard operations, or a parallel linkage for industrial applications. This way the machine’s specification can be ideally matched to the intended tasks. For the new midsize wheel loaders, Liebherr has retained its hydrostatic drive concept, and combined it with Liebherr Power Efficiency (LPE) as a means of boosting the machines’ handling capacity and economy. Compared with other wheel loaders in this size category, the innovative driveline concept cuts fuel consumption by as much as 25%. The wheel loader needs less fuel, and tyre and brake wear are reduced. A Liebherr development, the LPE system influences engine management pro-actively: the machine’s software is supplied with the accelerator-pedal position signal and

NEWS & REPORTS then computes the most efficient means of implementing the operator’s instructions. LPE optimises interaction of the driveline components. Liebherr’s design concept for its midsize wheel loader series ensures comparatively high handling capacities, since high tipping loads are possible despite the machines’ low tare weight. The new generation of diesel engines is now even more environmentally friendly and there have been many other improvements, too: precision common-rail fuel injection optimises the combustion process and reduces pollutant emissions. Exhaust emission control uses a diesel oxidating catalytic converter combined with a diesel particulate filter. In most situations, this filter can be actively regenerated by burning off deposits during operation of the machine, and the work in progress continued without interruption.

Safety, ease of control, straightforward maintenance These “Allrounders” now have -larger cab windows; the roof has been shortened and the upper part of the windscreen extended farther back. To the left and right of the steering column, the cabin trim has been lowered and replaced by glass. All-round visibility is therefore even

better on these new models. A fold-out window for the cab’s door is an option, and makes it possible to open the window completely. The cab is larger and safer, with even higher standards of comfort and convenience. The new wheel loader generation had excellent ride quality and even more stable, accurately controlled steering response. This is due to the two steering cylinders installed as standard on all these new-generation “Allrounder” models. Design changes to the vehicles’ frames increase stability even when travelling at quite high speeds. More severe surface irregularities are compensated for by the rear swing-axle suspension. All maintenance points can be easily and safely reached from ground level by opening just one single hood. This is possible because the Allrounders’ diesel engine has been turned through 90°. The transverse location of the radiator, with an air-intake in its customary position directly behind the cab reduces the amount of cleaning work needed, because the air drawn in contains less dust. Cooling system performance has also been uprated to suit the new technological requirements.

t the 2013 Bauma Liebherr is presenting its new R 922 crawler excavator, which is to supersede A the previous R 906 model. Together with the R 918 and R 926 crawler excavators that are to be seen on partner stands, the 22-tonne R 922 is a member of the newly developed product range with up to 30 tonnes service weight. Its Liebherr diesel engine with oxidating catalytic converter has a rated output of 105 kW (143 hp) and complies with Stage IIIB exhaust emission limits.

The new 22-tonne R 922 Crawler Excavator The new R 922 is designed for earthmoving and drainage work. Like all the new-generation excavator models, it is equipped with integrated excavator system technology for rapid, smooth working movements. In order to make the necessary flow volume available quickly and without one consumer significantly affecting another, and to ensure optimal use of the available energy, the Dual Circuit Positive Control hydraulic system is used. This allows the machine operator to save energy compared with other systems, since it reduces or in some cases entirely eliminates pressure losses. The driver benefits from the natural, harmonious movement cycles made possible by the load-dependent volume distribution principle. The R 922 exhibited at the Bauma is equipped with Liebherr’s Likufix quick-coupling system, which has enjoyed many years of popular success. The extensive range of backhoes and add-on tools, and Liebherr’s own patented bucket tooth system, enable the crawler excavator’s productivity to be increased still further.

Issue 01 | 2013

The steelwork has been functionally optimised to withstand continuously increasing demands for trouble-free operating life. The cruciform undercarriage increases stability and disperses stresses more effectively. The centre section and side members are designed to make cleaning quicker and easier. The tractive force of 190 kN makes the excavator highly manoeuvrable, even over difficult terrain. Higher grabbing force, a breakout force of 123 kN and a digging force of 149 kN increase the performance of the R 922 still further. The R 922’s cab sets new standards of ride quality and ergonomic control layout in its class. Low noise levels, an agreeable sense of space and fully automatic air conditioning as standard equipment guarantee the driver a pleasant place of work.

LB 44 Rotary Drilling Rig completes Liebherr‘s Range of Products for Deep Foundation Applications

he LB 44 rotary drilling rig newly presented at the Bauma 2013 is the latest development in Liebherr’s range of „deep foundation“ products and expands the LB series at the upper end of the scale. Based on its many years of experience and extensive know-how, Liebherr is reacting to the need for larger, more powerful machines of this type by presenting the LB 44. The LB 44 rotary drilling rig weighs approx. 160 tonnes and has been designed for drilling diameters of up to 3 m and drilling depths of maximum 92 m. The rig is driven by a V8 diesel engine offering 505 kW (677 hp) and complying with the exhaust certification stage 3B. Possible applications of the LB 44 include Kelly drilling, drill-ing with double rotary head, continuous flight auger and full displacement tool. The powerful rope crowd system with ap-prox. 56 t pull force allows utilisation of the entire length of the leader. This provides the operator with maximum perfor-mance and reliability even with the most difficult soils and extreme operational conditions.

High mobility at and between jobsites Distinguishing advantages of the new rotary drilling rig are its easy transportation and the short period of time between set-up and operation. As the leader can be folded back for transportation with all hydraulic hoses connected, no disassembly is required when moving between two jobsites. Subsequently, the LB 44 can be set up rapidly using the quick assembly system - this process barely requires more time than for smaller machines. If required the LB 44 can be disassembled into single parts weighing max. 40 tonnes. Thus, the rotary drilling rig can be transported throughout the world without any problems. For the basic design of the rig Liebherr remains true to its proven principles. This includes a large operating area thanks to parallel kinematics. Another aspect relates to the direct mounting of all winches on the leader. On the one hand, this allows for a direct view from the operator‘s cab to the main winch and, on the other hand, ensures that the ropes do not move during leader adjustment. Moreover, the undercarriage provides more stability thanks to long crawlers but still provides nearly the same small swing radius as the smaller rigs of the same product line.

Atlas Copco:

Cut high fuel cost and increase productivity with Atlas Copcos new drill rig FlexiROC T45

t Bauma 2013 Atlas Copco launches its new tophammer surface drill rig, the FlexiROC T45, along with its new rock drill COP 3060. As the name suggests, this new rig is flexible yet uncompromising when it comes to fuel efficiency, while the new rock further drill enhances drilling capacity. The FlexiROC T45 is a production workhorse, just like the ROC F9 before it, but outstandingly fuel-efficient and even more productive.

At the outset of development, demands were high for this new drilling rig. Not only was it expected to be incredibly efficient and productive, but also it was to be built on a tried and trusted platform that would provide high-availability and a wide area of use for both large and small applications. Naturally, it had to be extremely fuel-efficient.

Fuel consumption cut in half Field studies show that the FlexiROC T45 with folding boom, depending upon rock conditions, uses only half as much fuel as its predecessor the ROC F9 using the same rock drill. Additionally, the new rock drill COP 3060 mounted on a fix boom and aluminum feed, manages large diameters using the T60 drill string with outstanding performance and reliability. -Itâ&#x20AC;&#x2DC;s an incredible accomplishment to increase productivity and drilling capacity while reducing fuel consumption so dramatically. Everybody wins when thereâ&#x20AC;&#x2DC;s less environmental impact, a better working environment, and higher profitability, explains Mario Santillan, Product Manager at Atlas Copco Surface Drilling Equipment.

NEWS & REPORTS FlexiROC T45 with fix boom and the new COP 3060 rock drill and T60 drill string.

Innovative solutions Key to the success of the new rig lies in building on a proven platform fitted with a number of clever solutions to effectively reduce unnecessary energy losses and increase productivity. During operation, the operator can adjust the airflow and the dust collector fan speed according to actual working demands. The speed of the engine and compressor are then adjusted automatically. The FlexiROC T45 - with its efficiency, productivity, and superior cabin environment - is everything you would expect from Atlas Copco. However, these are not the only proofs that Atlas Copco is on the leading edge of drilling development. Compared to similar rigs on the market the FlexiROC T45 has 50% fewer hoses and 70% fewer couplings.

Sustaining the environment -Because hydraulic functions and electrical components are positioned in close proximity to their functions, components are easier to service and maintain and the risk of leakage is greatly reduced, explains Dieter Koss, Business Line Manager Drilling Equipment, Atlas Copco MCT GmbH who further adds: -The hydraulic tank is almost 60% smaller than on previous generations, making it possible to use biological hydraulic oil without increasing total costs. Should an accident occur, no costly environmental cleanup is needed, simply rinse with water.

Rotor impact mills for sand processing :

BHS-Sonthofen: Cubical shaped grains with round edges At BAUMA 2013, BHS-Sonthofen is showcasing its unique rotor impact mills, which are not manufactured by any other company in the world. They produce crushed sand with special characteristics that cannot be achieved in the same quality with any other machine: the grains are cubical, but their edges are rounded. Dry mortar produced with this type of sand is easier to use and makes concrete easier to pump.

Unique process increasingly being used for other applications Last year BHS-Sonthofen delivered numerous RPMtype rotor impact mills for new dry mortar factories in fast-growing Asia and the Middle East, further consolidating its position as market leader in machinery for producing dry mortar sands. BHS rotor impact mills employ a globally unique principle.

These rotor impact mills are increasingly being used for other applications than manufacturing sand for the dry mortar industry; for instance, they are being employed more and more frequently to make sand for ready-mixed concrete, as the concrete containing such sand has excellent pumping properties. Around the world, the number of rotor impact mills is also growing in the asphalt industry, in the manufacture of surfaces for sports facilities, as well as for grinding limestone, dolomite, gypsum, anhydrite and quick lime.

NEWS & REPORTS The hammers are wearing parts and can easily be replaced in just a few simple steps.

The rock breaks upon impact and assumes its cubical form. Repelled by the anvil ring, which is available in toothed and smooth versions, the material hits the hammers again, is further crushed, and thrown back against the anvil ring. This repeats until the material is small enough to pass through the gap between the rotor and the anvil ring, and falls out through two discharge chutes.

When it comes to crushing rocks, the rotor impact mill works best on slightly to moderately abrasive material. It can process feed sizes up to 56 mm. Larger feed sizes can be used for materials that are easy to crush, such as quick lime. Throughput can reach 75 t/h. The horseshoe-shaped hammers in BHS rotor impact mills are also absolutely unrivaled. The input material is fed into the machine from above through the centrallylocated feed tube. When it hits the rotor, it is accelerated outward at high speed by the centrifugal forces, where it is then caught by the horseshoe-shaped hammers, which impel it against the anvil ring of the annular housing.

The multi-phase crushing process serves to grind the edges of the particles, closely approximating the way sand is produced in nature. In practical applications, the rounded grain form makes it easier to process the material. For example, plaster made from this sand is easier to spread than if made from sand with sharp edges. The same effect makes the rotor impact mill an attractive choice for producing sand for ready-mixed concrete, which is then easier to pump.

The particles are caught and crushed between the rotating hammers and the anvil ring.

Processing technology :

BHS-Sonthofen: Gravel processing with BHS rotor centrifugal crushers At BAUMA, BHS-Sonthofen demonstrates the rotor centrifugal crushers of the RSMX series for processing hard and medium-hard rock to produce aggregate chippings and high-quality aggregates. The “rock-on-rock” principle and the patented rotor with just two centrifugal chambers offer considerable advantages over multi-chamber rotors in everyday practice.

Wear is virtually a thing of the past The requirements on the building materials concrete and asphalt – and thus on the gravel, chippings and sand used for their production – have continuously risen in recent years. Since demand for high-grade crushed sand and high-quality aggregates is also constantly rising, gravel and aggregate plants have to expand and equip their machine pools in order to meet the European standards and directives that require increased use of high-quality aggregates. BHS offers machines in four different sizes for throughput rates of up to 400 t/h.

Crushing with BHS impact crushers with vertical shafts and twin-chamber rotors is a popular choice in many plants for the production of high-quality aggregates. BHS rotor centrifugal crushers adopt the impact crushing principle: the material is fed vertically from above onto the high-speed rotor, which is mounted on a shaft with vertical bearings. In both chambers of the rotor, the input material is rapidly accelerated outwards due to the high circumferential speed, routed out via a naturally forming material bed and hurled at high speed against a fixed annular wall, generally consisting of an anvil ring made of heavyduty casting or an autogenous material bed.

Crushing function of the BHS rotor centrifugal crusher with anvil ring by means of the impact crushing principle.

The rotors patented by BHS with just two centrifugal chambers offer considerable advantages over threechamber and multi-chamber rotors: • • • • •

maximum input grain sizes of up to about 80 mm for hard rock and up to 150 mm for soft rock optimal material flow in the rotor, free from clogging 15 to 20 percent greater throughput rate with the same power consumption wear-related costs reduced by up to 25 percent exhaust air quantity reduced by more than 10 percent.

Choice of rock shelf or anvil ring The rotor centrifugal crushers from BHS can optionally be operated with an anvil ring made of heavy-duty casting or with a rock shelf, and can thus be variably adapted to a wide range of different requirements. If the anvil ring is used, the input material is crushed intensively by the hard impact of the rock against the impact wall, thereby developing the crushed face count of the chippings. Previously damaged rock and friable components are destroyed, significantly improving the test results of the final products. The stepped shape of the anvil ring causes the crushed material to be removed immediately from the crushing chamber without further abrasion.

HAVER NIAGARA F-Class â&#x20AC;&#x201C; Eccentric Screening Machine with New Bearing Concept:

Buffering of outer bearings reduces risk of bearing failure For the first time at bauma 2013 in hall B2, stand 129/236, the HAVER & TYLER Alliance will be exhibiting the new, patent-pending bearings concept in the F-Class eccentric screen series which will introduce a further innovation to processing technology. This new development was masterminded by HAVER & TYLER Allianceâ&#x20AC;&#x2122;s Innovation Management Department.

radial vibration is transferred directly to the outer bearings and support frame. This bears the risk of direct or mediumterm damage to the bearings. Buffering the outer bearings helps to extend the service life of the bearings with radial vibration and increase the availability of the screening machine during operation. Investing in our innovative bearings concept with the outer bearings encased in rubber has a positive effect on your ROI.

The concept has floating outer bearings embedded in rubber which buffer radial vibrations from the eccentric drive shaft. Vibrations such as these occur with strong load alteration when the screening machine feed rate suddenly rises during operation or when external force is applied, such as the direct impact of a hydraulic hammer used to remove blockages in a primary crushing plant or by excavator shovels in mobile plants. In standard eccentric vibration screens the outer bearings are not buffered and

The new HAVER NIAGARA F-Class has all the constructive and functional properties of the familiar HAVER NIAGARA T-Class. The modular, standardised assembly of the components, comprising the screen box, continuous drive train, spring brackets and support frame, simplifies maintenance and spare parts storage. Its wide range of operation, i.e. the various combinations of drive shaft speed and amplitude from 630 to 1,060 rpm and 3.1 to

NEWS & REPORTS 9 mm, enable the eccentric vibration screen to be perfectly adapted to suit all tasks and requirements. The optional reinforced screen box frame has been designed for heavyduty use or comes into play when higher demands are made of machine availability, such as in the mining industry. With a machine width of up to 3,000 mm the HAVER NIAGARA F-Class is extremely suitable for high feed and throughput rates. The inner and outer bearing size combinations of 150/110 mm, 180/130 mm and 220/150 mm are geared towards oversized outer bearings to ensure availability even with large loads. The HAVER NIAGARA F-Class eccentric vibration screen is fully balanced, i.e. the dynamic loads during screening machine operation are minimal, so that the static loads of the machine and feed material are determinative when dimensioning the steel structure. The HAVER NIAGARA F-Class is distinguished by the fact that various screening media can be combined with one another on one deck. Depending on the task on hand, screen meshes, pressure-welded gratings, snap-in screen panels or perforated plates can be combined. Adapters enable screening media from different manufacturers to be used; the screen operator is therefore not committed to any particular manufacturer. Subsequent modifications to the assigned media are also not a problem as the HAVER mounting rail system is not welded to the screen box crossbeam.

At bauma 2013 a double deck HAVER NIAGARA F-Class S 180/130 2400 x 6000 2D will be on show which has been designed exemplarily for armourstone screening and a feed grain of 0/450 mm. The screen deck sizes are 2,400 x 6,000 mm. The upper deck is fitted with perforated plates with 100-mm openings. The lower deck has variable configurations which can cope with various screening tasks. The combination on display, consisting of ISENMANN PU snap-in screen panels, TY wire and FlexMat modules, all of which are fixed down using the ISENMANN WS85 hold-down system, guarantee optimum stability, an open screening surface, selectivity and blockage-free operation in each phase of the screening process. The HAVER-Snap-Guard® wear protection system protects the crossbeams from wear.

The crossbeams in the screen box can also be optionally fitted with the patented HAVER-Snap-Guard® wear protection system that permits wear protectors to be quickly and easily replaced during machine servicing. The HAVER NIAGARA F-Class eccentric screen is suitable for all classifying jobs – from medium to large grain size – where load independent screening is necessary due to fluctuating feed rates and clinging feed material.

HAVER NIAGARA Hydro-Clean 2000 – New High Pressure Washing System with Increased Material Throughput: Minimized water consumption and improved cleanliness of bulk mineral products

The HAVER & TYLER Alliance will be introducing the HAVER NIAGARA Hydro-Clean 2000 under the aegis of HAVER NIAGARA GmbH. The HAVER NIAGARA HydroClean 2000 is the result of consistent further development of the well-known Hydro-Clean high-pressure cleaning system which has proved its cleaning power, high throughput rates, availability, economic efficiency and ease of maintenance in many different areas of application worldwide. The tried-and-tested modular system has been retained; new features include two adjacent washing rotors within one washing drum. The result is a high material throughput of up to 400 metric t/h and improved cleaning of clinging dirt from the 0/150 mm target grain size. As with all other sizes of HAVER NIAGARA Hydro-Clean only high-pressure jets are used for cleaning, these being directed at the raw material by rotor nozzles at pressures of up to 150 bar. As the jets of water rotate with the washing rotor the raw material is thoroughly ploughed through. Material is cleaned merely by the impact of the stream of water and the shearing processes in the raw material bed. Without exception all moving machine components are outside the flow of material. This makes the HAVER NIAGARA Hydro-Clean high-pressure washer a cleaning system with minimum wear. The machines low water consumption of 0.1–0.2 m³/t protects our natural resources and qualifies the HAVER NIAGARA Hydro-Clean for use in areas with a limited supply of water. It also creates a process that has a low water circulation, thus cutting operating costs. Its modular and compact design, installed total power requirement of 230 kW maximum and total weight of below 6,000 kg allow the HAVER NIAGARA Hydro-Clean 2000 to be used as a stationary, partially or fully mobile system or as a plant component.

NEWS & REPORTS New Holland Construction

New Holland Construction will launch new W170C Recycler wheel loader at Bauma 2013

New Holland: W170C Recycler

New Holland builds on the success of its W170C wheel loader in the Recycling industry, due in great part to its exceptionally low fuel consumption as low as 10 litres/ hour and best-in-class bucket payload, by launching a new version specially designed for the very tough, aggressive and dusty working conditions typical of waste handling and recycling facilities.

Advantages of the W170C: • • • • • • •

New Heavy Duty cooling box designed for extra efficient cleaning Full package of protections for extra operator safety and machine durability More power, less fuel consumption and more uptime with SCR Tier 4 interim solution More safety indoors with SCR that stops sparks More pushing power and faster cycles with Ecoshift More grip and less wear with the Heavy Duty axles with open differentials and 100% diff lock More fuel economy with ECO Mode and ECOSTOP

Issue 01 | 2013

New Heavy Duty cooling box copes with the most extreme dusty conditions New Holland’s unique cooling system design, where radiators are placed forming a box rather than the traditional approach of having them overlapped, ensures maximum cooling efficiency and makes it easy to clean the radiators. For the Recycling industry, where conditions are particularly dusty, New Holland has gone one step further to avoid clogging of the radiators and the consequent machine stoppages: the radiator in the W170C Recycler is built with more space between the fins so that dust and debris are easily blown away by the reversible fan. In addition, the cooling box is mounted behind the cab, far from the rear of the machine and from the ground, away from the dust. This placement is possible because of the rear-mounted engine, which has the added advantage of easier maintenance from ground level all round the back of the loader. This design results in a bigger load in your bucket, making the W170C the most productive loader in the 15-ton class today.

www.advanced-mining.com

156

NEWS & REPORTS A full package of protections for the toughest working environment Wood and solid components in waste can cause damage to the machine, if they fall from the bucket onto the lifting cylinders or the windshield, or if they get stacked in the machine’s articulation or under its belly. The W170C Recycler comes with a full package of protection guards for hoses, lights, cylinders, transmission shaft, fuel tank, windscreen, axles, front and rear chassis to ensure the operator’s safety, enhance the machine’s durability and protect its residual value.

More power and fuel economy with SCR Tier 4 interim solution The advantage of New Holland’s Selective Catalytic Reduction (SCR) after-treatment solution lies in the high combustion temperatures and the elimination of exhaust gas recirculation, which allows for optimised engine combustion. The result is more power density with less fuel; the engine delivers 950 N.m at 1300 rpm with just 6.7 litres; the high combustion temperatures cut particulates emissions by 90%. .

More uptime with SCR SCR doesn’t require a Diesel Particulate Filter (DPF), so that no fuel is used to burn PM in a DPF: it all goes to push in the pile. The machine never needs to stop for a parked DPF regeneration, so no time is wasted. Moreover, the operator can turn the key and stop working at any time, as there is no need to wait for the DPF to complete regeneration, which can require up to 50 minutes. All this results in optimised uptime, which is particularly valuable in recycling operations that typically work round the clock.

More safety indoors with SCR, the spark stopper A further benefit of New Holland’s SCR solution is greater safety on recycling jobsites, which are typically vulnerable to fire ignition risks: the system sprays AdBlue fluid in the exhaust to reduce NOx emissions by 50%, killing the sparks in the exhaust in the process. In addition, the

Issue 01 | 2013

maximum temperatures reached by the catalyst are about 50% lower than those of a DPF during regeneration, further lowering the risk of fire ignition.

More pushing power and faster cycles with EcoShift The EcoShift consists of three elements, which add up to maximum efficiency and fast cycle times. The lock-up of the torque converter is activated automatically during travelling, eliminating viscous losses, resulting in higher efficiency and 12% more pushing power available in second gear and faster acceleration. It is activated from 7km/h, when the second gear is engaged in order to maximise efficiency. It also enables the operator to climb steep slopes without downshifting to first gear. The five-speed transmission enables the operator to work at lower rpm and fully use the engine’s outstanding torque, resulting in more efficiency and faster cycle times. When braking, power inch prevents bouncing due to the automatic transmission cut off; on slopes, it acts as a hill holder, increasing the operator’s comfort and reducing fatigue.

More traction and less tire wear with heavy duty axles with open differentials and 100% front diff lock The open differentials mean that no friction is applied to reduce wheel slip, resulting in less tyre wear and lower energy losses. The front differential lock means that 100% of the available torque goes to the wheel with adherence – a big step up from the 60% of a limited slip differential.

Even more fuel economy with ECO Mode and ECOSTOP The W170C also features a new ECO working mode, which optimises engine curves and gear shifting strategy, achieving as much as 25% lower fuel usage than the MAX mode. Fuel efficiency is further enhanced with the ECOSTOP feature, which automatically shuts down the engine and the electric system after 5 minutes of idling, so there is no fuel waste and the turbocharger has the time to slow down and cool before it is turned off.

PIPE EXPRESS® from Herrenknecht nominated for the BAUMA Innovation Award

hiner y

ith Pipe Express® the Herrenknecht AG has developed a new semi-trenchless method for installing pipelines. In comparison with the open construction method, routes are W considerably narrower, no groundwater lowering is necessary and there is less impact on nature. This has a very positive effect on the grid operators‘ construction costs. Because of the especially ecological and cost-efficient working method, the development of this new system is subsidized by the German Environment Ministry. An expert jury has now nominated Pipe Express® for the bauma Innovation Award 2013.

Pipe Express® is a new mechanized method for the near-surface installation of pipelines of up to 1,000 meters in length and with diameters of 800 to 1,500 millimeters (32“ to 60“) using the half-open construction method. A tunnel boring machine loosens the soil which is then directly conveyed aboveground using a milling unit which is carried along. At the same time, the pipeline is installed underground. Since earthwork is reduced to a minimum and no groundwater lowering along the route is necessary, Pipe Express® has very little impact on the environment. This method is unique so far: For the installation of pipelines with a diameter of up to 1,500 millimeters, the soil is directly removed and not pushed aside. Pipe Express® is ideal, for example, for projects in which the groundwater level is only a few centimeters below the terrain‘s surface, in mainly swampy terrain or when nature protection is of special importance.

Issue 01 | 2013

Minimum manpower and a high degree of work safety The main components of the new installation system include a tunnel boring machine that works underground, a trenching unit with a buggy and an operating vehicle on the terrain surface. The modular design of the entire system allows easy transport and relocation, as well as high flexibility in changing project conditions. The compact system is remote controlled from the operating vehicle and no trenches have to be dug. This means that minimum manpower is needed, increasing work safety at the same time.

NEWS & REPORTS Cost savings thanks to minimum earthwork The new method has a positive influence on the realization and renaturalization costs in projects taking place in particularly challenging areas with unstable ground, water-bearing layers and at great installation depths. Compared to the conventional open construction method, with Pipe Express® the route width can be reduced by up to 70 percent, thus reducing the necessary earthwork. When crossing agricultural land, major losses of harvest and thus long-term compensation payments can be prevented compared to the open construction mode.

Environmentally-friendly installation of pipelines

PipeExpress

By using Pipe Express®, the influence of the construction activities on the surrounding environment can be reduced to a minimum. Acceptance by the population, land users and land owners is improved due to the reduced implementation of large equipment and thanks to shorter construction periods. The natural soil structure is only disturbed to a minimum, making subsequent recultivation easier. No complex groundwater lowering is required along the route and water-saturated soil layers are prevented from drying out. In addition, as the pipeline is installed fast and in one work step and fewer conventional construction machines are needed, emissions of exhaust gases and noise can be considerably decreased.

Test drillings and a first reference project completed successfully After Herrenknecht AG had initially carried out test drillings on the company site at the Schwanau headquarters over one year, the new machine technology could be applied in a first reference project in Sevenum, Netherlands at the end of 2012. „Pipe Express® has exceeded all expectations,“ noted project manager Andreas Diedrich with satisfaction and continued to explain: „The machine works with a tunnelling speed of up to one meter per minute, which means that 500 meters of pipeline were installed in three days.“ The construction company Visser & Smit Hanab is currently building a new high pressure gas line between Odiliapeel and Melick for the Gasunie grid operator. On a section of this line, the Herrenknecht innovation was put to use. Visser & Smit Hanab‘s managing director Wilko Koop confirmed: „I am very enthusiastic, everything worked excellently“.

Pipe Express® - the method When installing pipes with Pipe Express®, a tunnel boring machine drills the tunnel for the pipeline which is installed simultaneously. The excavated soil is conveyed directly to the surface via the milling unit and stored alongside the route. At the same time, the trenching unit functions as a vertical connection between the tunnel boring machine and the terrain surface. The operating vehicle accompanies the installation system and provides the entire logistics. These include a control stand for the operator, a power unit room, a high-capacity pump and a storage container for bentonite to reduce the skin friction between the pipe string and the ground. With the integrated crane system, assembly and dismantling work can be done in a very short period of time. The thrust force for the excavation unit and the pipeline is provided by a Herrenknecht Pipe Thruster.

Fully automated production of multi-layer concrete elements

he JFI method, an innovation by Sommer Anlagentechnik and SAA Engineering, granted with a patent in 2012, enables a highlyprecise automated production of multi-layer concrete elements with high flexibility and productivity. Till now the production of multi-layer concrete elements had been performed manually in most cases. The production of sandwich elements with a protruding facade cladding with klinkers, tiles, handcraft and natural stone needs much a lot of personnel and is not flexible. For this reason the market share is also quite low currently. This new process has been developed for the requirements of the Russian market. But due to the substantial advantages of this process for the production of high quality facade elements it will increase the market share of prefabricated concrete elements world wide. At the end of the year 2012 the very first plant world wide with this energy efficient, highly productive and ressource friendly technology will be taken into operation in the greater Moscow region. Another plant will start its production by the end of the year 2013. New fields of application in the production of complex prefabricated concrete parts are opened. Different building projects can be implemented economically. Energy and material costs are reduced, eg by saving plastic matrix and insulation material. By the possible use of different facade cladding elements such as steel, stone, aluminium, ceramics and photovoltaic the technical and aestethical quality of the buidling projects will be improved significantly.

The following developments have been implemented for that purpose: Production method for applying a joint filler The joint filler is applied automatically to the surface of the production pallet in a grid pattern according to the CAD planning. The joint filler mass has the following properties: it can form a joining contour. it does not connect with the joining concrete. it balances the tolerances of the production pallet. it has vibration absorbing properties and thus protects the facade elements from damages in the following compaction processs. the facade elements are position-fixed. it enables sealing and balancing of tolerances at the moulding edges.

Production method for feeding facade cladding elements (tiles, klinker, etc) automatically to a transport and cutting device and for placing them automatically and precisely with a robot on the production pallets The cladding elements are fed to a robot cell. The robot takes out one unit from a transporting unit (pallet, staple etc) and feeds it directly to a cutting device or directly to

The net product for the production in the prefabricated concrete plant is increased and also the competitiveness of prefabricated concrete parts over cast-in-place concrete. By fully automated, CAD supported production processes the efficiency of the production process will be increased and the working conditions in the factories will be improved.

VOLVO: Fume extraction system shortlisted for bauma Innovation Award

Category Mac ery Componenhtin s

olvo Construction Equipment’s extractor for bituminous fumes has been shortlisted for a bauma Innovation Award. The innovative design improves the operator environment on the company’s ABG pavers by substantially reducing fumes without significantly increasing fuel consumption, noise or affecting visibility into the auger channel.

Volvo Construction Equipment’s (Volvo CE’s) revolutionary extractor for bituminous fumes is one of three finalists in the machinery component category of the bauma Innovation Awards. The system, which is available as an option on Volvo CE’s C-Series ABG pavers, introduces a new way of removing fumes from the operator’s working environment. The innovative feature improves the working conditions of the operator – who sits directly above the auger channel. By delivering 83% efficiency, the system exceeds the National Institute for Occupational Safety and Health (NIOSH) guidelines which state that 80% of fumes should be captured. Volvo’s results have been independently certified by an environmental institute.

compact architecture. This also helps to maintain visibility into the auger channel which is vital to ensure consistent material flow and good quality, smooth paving.

Innovative and efficient During the majority of operating conditions, Volvo’s ABG pavers run on smart power which lowers the engine rpm

Behind the breakthrough The pioneering system works by using a fume intake, with a fan located directly behind it, on both the left and right hand side of the auger channel. The fan captures and transports the fumes via two tubes to the top of the paver where they are then released. This means that the air in the operator’s working environment is significantly cleaner than was previously the case. Volvo’s design is located at the back of the machine and features a very short distance between the intake and the fan – eliminating the need for additional piping and funnelling in the auger channel. This increases efficiency, prevents any loss of power and ensures that there is no effect on the operator’s visibility into the auger channel. Because extra power is not needed, smaller fans are used. These can be installed horizontally instead of vertically which offers a smaller, more

The new fume extraction system continues this environmentally friendly and fuel efficient approach and works just as efficiently when the machine is operated in smart power mode as it does when the machine is working in max power mode. As well as increased efficiency and visibility, another benefit of the Volvo design is reduced noise. The difference in sound between the system being on or off is insignificant – just 0.3 decibels. This means that there is no risk of the system distracting the operator or causing fatigue.

Nominated for the bauma Innovation Award 2013 – The

Wirtgen AutoPilot Field Rover revolutionizes road construction

s the leading manufacturer of road construction machinery, Wirtgen GmbH is renowned for its pioneering technologies and innovations. With the Wirtgen AutoPilot Field Rover, the company has now launched a technical development that for the first time enables fully automatic, stringline-free concrete paving. This system will enable road construction companies to complete jobs much more easily, quickly and, above all, economically. The jury of the bauma Innovation Award 2013 also deemed the AutoPilot Field Rover a pioneering development, and nominated it in the „Machinery Component“ category. When monolithic profiles such as concrete safety barriers or curbs are paved today, digital terrain models are created and so-called stringlines are secured in the ground along the profile. During paving, these are used by the machine for orientation purposes – a very timeconsuming method.

Fully automatic paving with the AutoPilot Paving is much quicker with the Wirtgen AutoPilot. The 3D control system comprises a computer that is integrated in the machine and an intuitive control panel. Two GPS receivers mounted on the machine communicate with a GPS reference station on the job site. A digital terrain model is not required, as surveying and programming is carried out on the spot. Conventional stringline-free 3D systems currently available on the market can only be operated by personnel trained in surveying, while the AutoPilot Field Rover is designed for simple operation by the machine operator, rendering special training unnecessary.

AutoPilot Field Rover: Stringlines are a thing of the past But what happens if a hydrant is positioned incorrectly or a gully is located 10 cm away from its marked site? With the traditional stringline method, the user modifies the line on the job site. This is also poses no problem for the Field Rover. The Field Rover comprises a GNSS receiver and a data collector on which the software developed by Wirtgen is installed. As during normal survey work, the section to be paved is staked out with a plumb rod and individual measuring points defined. The highlight of the Field Rover is that the software calculates the optimum course on the basis of the measured points, creating a virtual stringline, so to speak. The data are saved on a USB stick that is then simply connected to the machine. It is not necessary for the operator to enter any additional data by hand. The Wirtgen slipform paver then automatically moves to the starting point calculated during the survey, and from there moves along the defined course.

NEWS & REPORTS If the concrete profile is to be paved up to existing roadway edges, the user can calculate the optimum virtual stringline within minutes. For the first time ever, it is now truly possible to eliminate the conventional stringline in practical applications. Road construction companies stand to benefit in many ways – for example the Field Rover lowers paving costs considerably in comparison to conventional methods. As it bases its calculations on the actual job site measurements and does not rely on construction drawings, it achieves a higher degree of paving accuracy and quality. In addition, the slipform paver can automatically negotiate obstacles. Apart from enhancing safety on the job site, this feature also brings further cost reductions, as machine damage that frequently occurs when the machine drives over obstacles is effectively eliminated.

With the AutoPilot Field Rover, Wirtgen is introducing 3D technology for everyone. The price of the system is significantly lower than that of existing 3D systems, as the Wirtgen system is optimally integrated in the machine and optimized for the respective application. What‘s more, this ingenious tool is very easy to use, so that there is no need to consult a survey technician.

BAUER Spezialtiefbau GmbH Drilled Monopile Foundation for a Tidal Turbine

number of BAUER Group companies were involved in a project in the summer of 2011 to install a monopile into the sea bed as the foundation for a tidal turbine. The contract was executed by BAUER Renewables Ltd. with the help of its parent Bauer Spezialtiefbau GmbH. Tidal flows are a good source of renewable energy, as they provide a regular and predictable output. In the North Sea off Scotland, close to the Orkney Islands, a test field of the European Marine Energy Centre (EMEC) has been established for such projects aimed at generating renewable energy.

FOR MORE INFORMATION AND CONTACT: BAUER Maschinen GmbH D-86529 Schrobenhausen Tel. +49(0) 8252 97-0 Retrieval of the drilling unit after a successful operation

In order to install the monopile foundation, Bauer‘s engineers designed an entirely new drilling rig which is lowered to the sea bed and is operated hydraulically from on-board a floating vessel. The new rig was designed by Bauer Maschinen, and within just a few months was ready for operational use. Its name: the BSD 3000 – BSD standing for Bauer Seabed Drill. Initial sketches were produced in October 2010, and in March 2011 manufacturing of the rig began. In the subsequent phase the project was subject to strict timing constraints. Every day was planned exactly: for testing, transportation from Hamburg to the UK port, transfer from the port of Scrabster to the drilling location, and for the drilling phase itself. The work on-site had to take account of the tides, waiting for the hour or two in which ebb turned to flood and vice versa. Only during that period of relative calm was it possible to lower the key components of the rig: the drilling template with casing oscillator, guide casing and drilling tool. The actual drilling was possible even when the sea was rough. The special ship was held in position by a propulsion system based on GPS. Thanks to detailed preparation, the drilling operation ran almost perfectly. The drilling was carried out using a full-face roller bit with heavy weights. The cuttings were transported to the surface by an air-lift system. The torque was provided by a modified BG 28 rotary drive. At a depth of around 37 meters underwater, a 23 metre long monopile with two metre diameter was grouted into an 11 metre deep rock socket with high-strength mortar. The one megawatt turbine will be installed approximately 12 metres above the sea bed – a depth at which it is able to make optimum use of the tidal flows.

HERMANN KIRCHNER Bauunternehmung GmbH PAST (Process-Reliable Automated Road Construction) • Increased quality and durability of asphalt roads • Reduced construction-related congestion • Diminished burden on public budgets The cooperative research project PAST (Prozesssicherer automatisierter Straßenbau) [Process-Reliable Automated Road Construction], which was concluded in 2012 with a key role being played by several STRABAG Group companies, aims at making decisive improvements to important functional properties of asphalt roads such as noise absorption, evenness, grip and durability by eliminating quality-influencing weaknesses during the construction and logistics processes. This involved around four years of intense research to develop state-of-the-art approaches in automation from which machine technology innovations were derived for the entire construction process chain. Practical testing was carried out along trial sections on four motorways and two federal highways in Germany.

In 2010, the 15 procedures and techniques (so-called demonstrators) which had been developed to date were subjected to a first practical test along a trial section of the German A4 motorway near Jena. The procedures and construction techniques were then further refined and successfully tested at five additional trial sections.

Quieter, safer, more durable, and equipped with intelligent sensor technology: this is the road of the future. The innovations will benefit not only road users, but will also help to reduce the burden on public budgets, minimise construction-related congestion, which results in an estimated 4.4 billion hours of lost time, and shorten the intervals between road maintenance.

A further innovation is the use of data transponders placed in the asphalt during the paving process. The transponders will not only store all relevant construction data and material values, but will also allow the asphalt temperature and thickness to be measured, stored and read as often as desired. This is not only of immense importance as information for the production process, but as part of an intelligent road sensor system can also serve as a universal source of information and early-warning system (e.g. during icy conditions or to determine the current road conditions).

The recently concluded interdisciplinary research project PAST – participants included two German universities, several industry partners, the German Federal Highway Research Institute (Bundesanstalt für Straßenwesen – BASt) as well as the STRABAG Group companies Deutsche Asphalt GmbH and Hermann Kirchner Bauunternehmung GmbH as project leader – shows that innovative approaches to this subject already exist. The aim of the project is to identify and eliminate nearly all quality-reducing factors during the construction of asphalt roads. The goal is to produce high-quality, long-lasting road surfaces through the use of largely standardised and automated processes along the entire process chain, from the mixing plant to the construction site. The necessary construction techniques were developed in a series of steps over the duration of the project (2008-2012) and can be used in the construction of roads following their testing and conformance to standards.

Issue 01 | 2013

The Brandenburg Roads Agency (Landesbetrieb Straßenwesen Brandenburg) commissioned KIRCHNER as project leader to provide maintenance works along a seven-kilometre section of the A111 motorway near Berlin. Nine different asphalt types were laid and, as part of the PAST project, will be measured, observed and assessed over the whole service life.

“Our federal highways and motorways show significant deficits in terms of quality. This makes analysing and improving the processes so important,” says Prof. Josef Kunz, director of the road construction department at the German Federal Ministry of Transport, Building and Urban Development (BMVBS), convinced of the research project’s innovative approach. The necessity to improve the quality is clear to see. Growth forecasts predict 20 percent growth of non-commercial and 40 percent growth of commercial traffic by the year 2015. A complete contemplation of the process chain not only includes the use of weak point analyses and improvements in construction techniques, but also the testing of different asphalt compositions. Various mixtures were produced, including the first-ever layed asphalt with a porous surface,

Online Grain Size Analyzer One of the main tasks of process monitoring, system control and quality assurance in various branches of the industry is to determine the grain size distribution of granular material. The range of tasks extends from pharmaceutics and food production to chemistry, as well as to construction and mining industry. There is a central role to processing of mineral raw material, particularly in mining, since here the processes of crushing, sorting and grading, which are directly linked to the distribution of grain size of the material, can be optimized, supervised and controlled. The capturing the grain spectrum of a material mixture before or after each process step is usually done through sampling and analysis through well-established screening machines in the laboratory, often preceded by preparation of the specimen, for example drying. Since it is difficult to determine grain size of dust and ultrafine grains, laser-based analysers, which are integrated in the laboratory or partly in the process chain, have been developed. However, the timeconsuming and costly sampling from the process cycle with subsequent laboratory analysis, as well as the limited range of application and the sensitivity of optical methods call for the development of a robust measuring system for use in a broad range of application for the online analysis of the grain size distribution of granular material. The development and application of a new method to determine grain size is based on pulse-induced vibration.

NEWS & REPORTS Measuring Principle

Currently several plants are in industrial operation:

During its transport in various media collisions of granular material with solid bodies generate impulses, that evoke oscillations in those solids. The characteristics of the oscillations are directly proportional to the pulse intensity, and in case of the same density of the granulate material, they are directly proportional to the grain size. The correlation of the inter-class time-bound intensities of the signals results in a distribution, which is directly proportional to the distribution of the grain spectrum that has generated vibrations in the analysed timeframe. A proactive one-time calibration of the system allows for the assignment of signals to the respective grain categories, making an online grain size analysis possible.

pplicability, performance and safety of mobile machines are determined by their work equipment. Thus it contributes heavily to the technical solution of construction as well as forestry, agriculture and transportation machines. Within the scope of a research project funded by the BMBF a parallel kinematics, also known as “Hexapod” has been developed to be applied as device interface (e.g. tractor), as linkage for blades (e.g. grader) and to combine different equipment versions for wheel loaders. The latter shall be used to demonstrate the numerous advantages that come with this innovation. Because of its mobility and large variety of tools the wheel loader as a heavy equipment machine is adjusted to different processes (e.g. loading, mixing, milling, hammering, sieving, displacing). This diversity is especially demanded by the classes from 2t to 12t weight that have a market share of more than 60%. Up to now this demand has led to a wide range of technical solutions for wheel loaders, compact-, front-, telescope- or swivel loaders and tools with integrated prismatic or revolute module. The HEXAPOD has been developed in addition to or rather as a replacement for these solutions, since it is able to move the tool (e.g. loading shovel, pallet-fork, milling head, hammer) using the full capacity of all 6 degrees of freedom in relation to the machine. With this manipulator the wheel loader can tilt, lift and telescope a loading shovel without moving, put down a pallet whilst reaching over an obstacle or push bulk material forward with a laterally displaced tool. As a result many different new ranges of application emerge, which increases the practical value and the advantage in competition for wheel loaders.

The HEXAPOD parallel kinematics represents a framework of hydraulic cylinders. Because of its nonlinear coupled transfer characteristics a special motion control and an ergonomic control unit is required. Those provide at the same time the basis for valuable assistance applications such as automation of recurring manipulations, processing information about the working space, compensation of inclination and spatial damping. Another advantage is the modularity. Whenever a customer intends to use less than 6 degrees of freedom the hydraulic cylinders can be replaced by rods. This kind of framework is particularly rigid; it reduces the net weight and improves the operator´s sight. By adding the modifications to a WEIDEMANN 3070CX wheel loader the following targeted research goals were accomplished:

Technical University of Kaiserslautern - Computer tomography enables orientation analysis of steel fibers in reinforced concrete

raunhofer Institute for Industrial Mathematics and Institute of concrete structures and structural engineering at TU Kaiserslautern team up as one of three nominees in the category „Research“ in this year‘s Bauma Innovation Award competition.

A look inside – computer tomography enables orientation analysis of steel fibers in reinforced concrete The nomination is based on pioneering work on steel fiber reinforced concrete (SFRC) that is expected to dramatically raise the acceptance of this material in the building industry. The increased use of steel fiber concrete offers great potentials in terms of time-savings and costefficiencies, in addition to being an environmentally friendly construction method. Some typical applications are composite slabs, load-bearing floors and walls, industrial floors, steel fiber reinforced shotcrete, segments for tunnel construction, and underwater slabs. A production method of uniform steel fiber reinforced concrete under building site conditions has remained a mystery. Established testing methods (wash-out, electro-magnetic, and photooptic systems) provide information at great expense about the volume fraction of fiber. However, none of these have offered a reliable and verifiable analysis of the fiber distribution and direction.

construction where steel fiber reinforced tunnel segments have been economically used after the fibers‘ preferential direction was verified absolutely as being parallel to the border of the formwork. Currently, the focus of effort is on fiber tomographics in stress cracks with the aim of acquiring an improved understanding of load bearing capabilities. The safe application of steel fiber reinforced concrete offers many new perspectives to the entire building industry.

Help has now arrived in the form of the algorithms developed at Fraunhofer ITWM, which form the basis of MAVI software. The engineers have succeeded in implementing the world‘s first descriptive testing of the fibers according to their positioning in space, projected length, and diameter. This news has been greeted with great national and international interest. The Institute of concrete structures and structural engineering at TU Kaiserslautern has implemented this new development for scientific testing of norms and for the study of the post-cracking behaviour of SFRC. The testing method is now ready for use in the assessment of damage claims and quality monitoring.

he Liebherr Compact Loaders on display at the 2013 Bauma represent an entirely new machine concept. The L 506 C und L 508 C combine high performance with maximum safety and extreme versatility on all kinds of task. Both models are exceptionally low in height, at less than 2,500 mm. The L 508 C with its 49 kW (67 hp) engine is the only compact loader with centrepivot steering in this performance category to have such a low overall height. The excellent versatility of these models opens up many additional applications, for example in road building, drainage, forestry and agriculture and in the service of local authorities and communities. The frequent changes of operator and workplace constraints associated with such operating tasks present no problems. The new Liebherr Compact Loaders are an addition to the existing range of stereo, medium-size and large wheel loaders.

An excellent all-round view and straightforward controls The driver’s cab is comfortably equipped, with an aboveaverage window area. The operator of the Compact Loader has an unobstructed view of the power tools or working attachments, and the well-positioned rear and side mirrors for good all-round visibility. The conicalpattern lifting gear improves visibility even further; the driver can react quickly to any situation arising close to the machine. This guarantees maximum possible protection for people in the vicinity, the equipment and the load.

Excellent weight distribution for optimal productivity The Compact Loader’s reduced height automatically lowers its centre of gravity. Its tipping load limit and stability, even on uneven surfaces, are higher. The well-matched relationship between operating weight and tipping load is another productivity bonus for these machines. For optimal force distribution, the lifting cylinder is centrally located on the tapered lift arm. Accurate parallel movement of the working equipment is the key to exceptionally fast and precise work: loads are positioned and lifted reliably without manual correction or loss of material. If a fork is fitted, a payload of more than two tonnes is available.

The controls in the operator’s cab are ergonomically laid out for intuitively correct operation; they can be individually adjusted by the operator for reduced fatigue and maximum performance. This ease of operation enhances both productivity and safety. The Compact Loader’s operator can concentrate fully on the task in hand and devote full attention to working and manoeuvring movements.

NEWS & REPORTS High mobility – rapid readiness for work Thanks to the low headroom it needs, the Liebherr Compact Loader can easily reach its working location even if access is restricted by tunnels or underpasses. It can also be carried without difficulty on tipper vehicles) or in a high-cube container. If moved on a conventional transport vehicle, the maximum height does not exceed four meters. Mobility is enhanced by the machines’ lightweight construction, which in normal circumstances does not exceed the statutory weight limit. A big range of ex-factory add-on options is available to equip the Compact Loaders for a variety of different tasks. With the easily operated quick coupler, add-on attachments can be installed and removed rapidly and effortlessly.

High-performance equipment, easy maintenance The L 506 C Compact Loader weighs only 5,180 kilograms and has a tipping load of 3,450 kg. It has a standard 0.8 m³ bucket and is powered by a 45 kW (61 hp) diesel engine. With a operating weight of 5,600 kilograms, the L 508 C Compact Loader has a tipping load of 3,850 kg. It has a 1.0 m³ standard bucket and a 49 kW (67 hp) diesel engine. Easy access to all maintenance points and radiators/oil coolers is another factor that boosts the productivity of the new Liebherr Compact Loaders.

KAISER AG Fahrzeugwerk - Kaiser Walking Mobile Excavator Innovative design, ergonomics and driver comfort are the hallmarks of the latest generation of walking mobile excavators from KAISER.

he innovative design of KAISER’s new S-Line cannot fail to impress. Rounded bodywork, enhanced ergonomics and optimised optional equipment not only create visual harmony but also ensure a significant increase in driver comfort.

Perfectly formed The new generation of walking mobile excavators reveals a consistent focus on dynamic and at the same time functional design of every element of the vehicle – whether it’s the cab interior, the field of vision inside and out of the cab or the positioning of the heating and airconditioning system. The cab and superstructure form a single unit which in turn harmonises with the vehicle as a whole. The new design is based on the principle of a compact radius excavator, offering outstanding all-round visibility of the entire working zone. The driver has a direct view of each of the excavator’s pads from the cab. Integration of the new, significantly more powerful drive and cooling system called for innovative technological concepts and presented a major challenge in the design phase. When it came to developing and designing the

Issue 01 | 2013

new walking mobile excavators, KAISER benefited from the excellent collaboration between its own development team and established industrial designers from the firm “Design Department” based in Linz, Austria.

Design meets performance The large, dynamically designed air suction and exhaust vents provide an immediate clue to the performance class of the new S-Line. The new models are equipped with the powerful COM IIIB engine which already meets future requirements of the EU vehicle emissions standard. Thanks to their lower centre of gravity, the new vehicles in the KAISER S-Line boast even greater stability on extreme slopes.

NEWS & REPORTS Emphasis on driver comfort Walking mobile excavators are built for deployment in arduous and inaccessible terrain. The driver commonly spends more time on the job compared with other construction sites. For that reason the cab has been specially conceived with the needs of the user in mind. The ergonomic layout of the extensive range of functions has been chosen to greatly facilitate the work of the driver. Convenient operation is just as important as a comfortable seated position. Enhanced operator comfort was a major focus for the S-Line, the aim being to achieve a measurable increase in productivity on long working days. The complexity (number of different functions) of operating a walking mobile excavator should not be underestimated; it is comparable to flying a helicopter and requires full concentration at all times. New joysticks make for easier operation of the many hydraulic adjustment facilities and a wide range of attachments. While the rotary button and switches are readily accessible in the side panel, the standard display on this series is optimally located within the driverâ&#x20AC;&#x2122;s field of vision and is intuitive to use.

Issue 01 | 2013

Various fresh air vents ensure a pleasant climate inside the vehicle. Optional extras such as air-conditioning, storage compartments for documents and provisions, cooled bottle holder and hands-free docking station for a mobile phone provide even greater operator comfort in the new excavators.

Carefully chosen colour scheme The colour scheme has been revised for this new generation. A combination of grey and black tones ensures a tranquil atmosphere inside the cab. The exterior is dominated not only by the familiar KAISER blue and yellow but also by the new anthracite finish for the undercarriage.

A revolution in the demolition breaker segment: Wacker Neuson’s EH 100

n extremely high demolition performance with a single stroke impact energy of 100 Joule combined with a good power to weight ratio – these are the facts which are readily available at this point in time regarding Wacker Neuson’s new demolition breaker. Its name: EH 100.

The new demolition breaker segment: Wacker Neuson’s EH 100 Wacker Neuson’s new demolition breaker, a world’s first within the range of demolition breaker, will be introduced to the market punctually for the Bauma 2013. “Powerful, formidable and unique” is how Dennis Vitze, Product Manager for Demolition Technology at Wacker Neuson, describes the new demolition breaker. “Our idea was to move into a higher performance class in the demolition segment with our new demolition breaker, while remaining easy to transport and cost efficient. This goal has been definitively achieved with the EH 100.”

The results are remarkable: On the one hand an extremely powerful demolition breaker in a high performance class, on the other hand a tool easy to operate, transportable and cost-efficient thanks to its ergonomic design and the many proven technical details coming from Wacker Neuson. The building world can thus await with interest a revolution within the demolition breaker segment. Let us look forward to a demolition breaker of a new dimension with a high degree of application flexibility and lots of power under the hood.

The single stroke impact energy of 100 Joules is packed into a compact hood with an absolutely new design. The ergonomically shaped, fully spring-mounted hood allows the operator to precisely guide the demolition breaker while maintaining visual contact with the chisel’s tip. This helps to make the demolition application extremely efficient. Plus all this is bolstered by the low hand/arm vibrations (HAV) of 5.8 m/s”. Wacker Neuson’s proven hollow piston percussion system with striker rod is also in operation in the EH 100 and does so without wear-prone seals and gaskets. The system also makes possible the extremely high demolition performance. Also well-known from other electric demolition breaker by Wacker Neuson is the wear-free asynchronous motor with its brushless drive. It goes without saying that both percussion system and motor are precisely adjusted for the EH 100.
