EDUCATION

Introduction to the raw materials production Deposit Characteristics, relevant to Mining

by Univ.-Prof. Dr.-Ing. habil. H. Tudeshki Surface Mining and International Mining TU Clausthal | Germany

Following the completion of our further education series, “Securing Supply of Raw Material, Deposit Reconnaissance, Calculation of Reserves, and Geo-mechanics and Hydrogeology”, which serve as the basis for planning of mining projects, we are pleased to inform you that the current AMS issue will start discussing a new topic in its further education section, which is: “Introduction to Mining of Raw Material”. The first issue of our new further education series will discuss “Deposit Characteristics Relevant to Mining”, and resulting methods of extracting raw material in underground mining. Knowledge on some deposit parameters is necessary for selection of an appropriate mining method,. These parameters include the volume or mass of the deposit, its geometry, the form of the deposit, its development and location, geo mechanical and hydrological circumstances, as well as techtonically caused discontinuities. In the following, all these deposit characteristics relevant to mining are being discussed. Since these characteristics are relevant to both mining of mineral raw material in open cast mining, as well as in underground mining, they will already be explained in the introduction section A.

Contents of deposits Contents of the deposits include resource mineral contents and possible impurities, which reduce the quality rating of raw material (e.g. phosphor and sulfur content of iron ore), as well as dead rock portions. The distribution and regularity of these contents also need to be taken into consideration. Irrespective of the type of mining, i.e open cast mining or underground mining, a mining method needs to allow for a mixing of various contents of the deposit. The contents of the deposit, i.e. the absolute amount of resource minerals in a deposit, can be calculated from the resource mineral content (specified in kg/t or %). A profitable deposit should possess a resource mineral content above the cut-off grade. The cut-off-grade specifies the limit of profitability. Economical mining is not possible in case the deposit shows lower contents than the cut-off-grade. The cut-off is the average mineral content of a deposit or of parts of a deposit, which would result in a cost and revenue

Issue 04 | 2012

balance of zero. However, it should be noted that the cutoff grade can change, as it mainly depends on the market price of resource minerals.

Geometry of a deposit The options of creating access to a deposit and selecting an appropriate mining method are determined by the location of resource minerals in the earth crust, their form, extent, layer depth, as well as the morphology of the mining field. The fundamental decision of mining a deposit as open cast mine or as an underground mine, is mainly based on the layer depth of the deposit. Near-surface deposits can be mined in open cast mining, deep ones in underground mining. In case a deposit lies in a border area, i.e. if mining would technically be possible both in open cast mining, as well as in underground mining, the decision is made on the basis of economic and ecological aspects. As such it is possible to mine near-surface raw material in underground mining, in case of ecological restrictions. The form of a deposit can be corridor-shaped, seamlayered, thick or irregular. Corridor-shaped deposits are mostly steeply standing, with a relatively low thickness. Seam-layered deposits are flat to oblique and also have a relatively low thickness (Figure 1). Thick deposits are characterized by a very large thickness. Dipping of the deposit is also of importance for mining. Dipping is specified in gon (whereby 360 degrees are exactly 400gon and a right angle is 100gon). Dipping is called flat when the deposit is inclined in an angle of 0 to 20gon.

www.advanced-mining.com

EDUCATION

An intermediately inclined deposit shows dipping of 20- 40gon, a heavily inclined deposit has an angle of 40 to 60gon. From dipping of 60gon and above the deposit is called steep standing. When discussing thickness of deposits, they are often divided into deposits with low, medium and high thickness. Raw material deposits with low thickness have a thickness of less than 3 m. Heavy deposit formations have a thickness of 3 to 20 meters. In case of more thickness, the deposit is called a deposit with high thickness. Apart from the already mentioned parameters of depth, form, dipping and thickness of a deposit, there are other characteristics such as regularity of boundary areas between the resource mineral and surrounding rocks, as well as the extent of deposit in strike and dip.

Geo-mechanical Conditions It is very important to have knowledge on geomechanical conditions of the deposit, both for open cast mining, as well as for underground mining. In case of open cast mining, such knowledge is particularly important for appropriate slope geometry. This applies to resource mineral slopes, as well as to slopes in excavated material and dumps. But it is also essential to have knowledge on the strength of the resource mineral. Based on the strength of the raw material to be mined, it has to be decided whether for optimal loading blasting of rocks is necessary, or whether explosive-free mining is possible.

Issue 04 | 2012

The rock-mechanical characteristics of the resource mineral and surrounding rocks are of immense importance, also in underground mining. In order to appropriately dimension an underground mine structure, like for example adits or chambers, it is important to have knowledge on the strength of rocks. A reliable dimensioning is also very important for massive hard rocks and pillars.

Hydro-geological Conditions Hydro-geological circumstances have a critical influence on mining operations. In open cast mining, raw material can be extracted both through dry or wet mining, subject to the ground water situation. Alternative to wet mining, it is possible to lower the ground water. With regard to stability of slopes, it is also important to have knowledge on water-bearing strata and their permeability, as well as on the ground-water level. Similarly, this applies to underground mining. Waterbearing strata pose a danger to underground mining. Therefore an exact determination of the topography is needed.

Tectonic Discontinuities And Geological Anomalies These influencing parameters include dislocations, as well as deposit characteristics, like for example gas drainage. Exact planning of mining operations require exact data on form and locations of dislocations.

www.advanced-mining.com

EDUCATION Geographical Position Apart from the already described parameters, which are directly related to the deposit, there are further influences, which can enable or inhibit mining. Such include political circumstances and resulting security of investment in the country, in which the mining field is located. Another important factor is environmental legislation. In addition, based on the sensitivity to transport of the respective resource mineral, physical proximity to costumers, loading stations, ports, etc. are important. The same applies to the type and quality (status) of transport routes. Due to their low revenues, mass raw material like sand and gravel do not allow for long transport routes. Other raw material, like for example metal ores or mineral coal can easily be transported over long distances.

Mining of Solid Raw Material in Underground Mining Underground mining is fundamentally different from open cast mining, in which the mineral raw material to be mined is exposed through baring of . overburden layers on the raw material. In case the deposit lies too deep, baring of the overburden is neither technically nor economically recommendable. In such cases the mineral raw material is mined in underground mining. Following is a discussion on various methods, techniques and operating equipment used in underground mining.

of the deposit. Advance preparatory workings are part of the development and provide appropriate preconditions for application of the selected mining method. Development of a mine will be introduced in the first section of the description of methods and techniques. The second section will look at the usually applied mining methods.

Development of a Mine The development works serve to establish a permanent connection between the deposit and the day level. Out of all mine structures, development works have the longest durability and are therefore preferably constructed in the surrounding rock. Prevailing geological conditions and the intended method of mining are critical parameters for development and design of the mine. Mine structures for surface mining are adits, inclined drifts or coils, as well as open shafts. Further preparatory workings, which allow for an underground access to the deposit are blind shafts, bottom headings, cross headings, mountains, as well as drivings, like for example top roads and conveying roads. Figure 2 shows an example of mine development. After mining of raw material was not possible any more in open cast mining, the deposit was mined in underground mining. For this reason a shaft was driven and a ramp was driven from the open pit mine bottom. From these mine structures, mine roads were constructed in the direction of the deposit. Based on the used mining method, advance preparatory workings are to be constructed from this mine road system. The most important mine development works are further described in the following discourse.

Methods and Techniques in Underground Mining The methods and techniques of underground mining are divided into mine development, as well as into different mining methods. In mining language, the term â&#x20AC;&#x2DC;developmentâ&#x20AC;&#x2122; mainly means construction of mine openings, through which the deposit can be accessed. The mining method, which is selected on the basis of the present deposit value, is in relation with the development

Issue 04 | 2012

Adits The classic preparatory working in mountainous terrain is the adit. Contrary to a tunnel, an adit is characterized by the fact that it only leads to the open on one side. An adit is located as deeply as possible at a slope, so that a large part of the deposit can be developed. Furthermore, adits are usually constructed with sloping to the hole top, so that water can be discharged from the mountain.

EDUCATION While reviewing the investment efforts and operating expenses caused by adits, it becomes clear that these are among the economical preparatory works. Due to the demands on the topography of the terrain and the depth of the deposit, adit operations have become rare. Figure 3 shows an adit in the Rammelsberg mine in Goslar. Mining of silver started over 1,000 years ago in this mine.

The selected inclination mainly depends on the haulage means, like for example belt conveyor systems and mobile transport equipment. Drifts are not only mine structures coming from above ground. Other underground mining structures for mine development are also called drifts. In case these drifts run vertical to the deposit dripping, they are called cross-drifts. Drifts that run parallel to dipping are called main headings. Further headings are needed for the preparatory works, which allow for mining of the resource mineral with the planned mining method.

Drifts Mineral raw material deposits can be developed with inclined drifts, the so-called day drifts. These can either be constructed as a straight-line ramp, or as a spiral coil. A fundamental difference to adits is the downward inclination, resulting in water flowing into the mine. Subject to the applied transport equipment, inclinations of up to 18% can be realized with ramps and spirals.

Shafts If the raw material to be mined lies very deep, development can only be done through a shaft. Shafts are vertical mine structures, that are divided into surface shafts and blind shafts. Surface shafts lead from day level through the overburden up to the deposit or near the deposit. Blind shafts, however, do not lead to the day level; they connect several floor levels of a mine.

Geothermal Use of Deep Rock Reservoirs (Hot Dry Rock Systems):

Is it possible to predict the chemical composition of water?

by Elke Bozau & Wolfgang van Berk Institute of Disposal Research | Hydrogeology Clausthal University of Technology | Germany

he chemical composition of geothermally used water is of critical importance to the operation of a geothermal plant. Scalings (e.g., barite, halite) can precipitate from highly mineralised water and interfere with pumping. The disposal of these scalings, which can also include radioactive precipitates, entails considerable costs. In extreme cases, scalings can even halt operation of geothermal facilities. In addition, the gas content of geothermally used waters has to be taken into consideration while planning energy generation. As such, it is for example possible to set a specific pressure in the geothermal facility to prevent dissolved gases from outgassing. Deep geothermal rock reservoirs are divided into deep aquifers and hot dry rock systems (also called petrothermal systems). During geothermal energy generation, the water of deep aquifers is pumped up and after its heat has been extracted, it is again injected into the aquifer. In order to win heat from hot dry rock systems, surface water is injected into a geothermal reservoir, heated there, and then it is further processed like the water of deep aquifers. The chemical composition of water in deep aquifers in Germany is relatively well known, and the processes taking place in the aquifers can be described with generic hydrogeochemical models. However, the forecast for chemical water quality of hot dry rock systems is subject to significant uncertainties.

Fig. 1: Salinities in drinking water, sea water and deep groundwaters, which are already used or are planned to be used for geothermal energy generation. The chemical composition of the geothermally used waters can cause corrosion, outgassing, and scalings (precipitation of minerals) during cooling of the waters. While technically designing a geothermal power plant, these conditions must be taken into consideration.

Hydrogeochemical Modelling to Predict Water Composition

Deep formation water Geothermal plant Research well

www.advanced-mining.com

TRANSFER OF TECHNOLOGY One of the challenges in hydrogeochemical modelling of such highly mineralised waters is the calculation of activity coefficients of the aqueous species, which are in temperature and pressure ranges that are typical for geothermal wells. It is for this reason that, within the framework of the project “geothermal energy and high performance drilling research“ (gebo), a thermodynamic database was developed, which can be used for the PHREEQC programme [6]. In order to do so, the database “pitzer.dat“, provided by the PHREEQC computer programme and serving to calculate the activity coefficients in high saline solutions [7], was further expanded for geothermally used waters by relevant elements, aqueous species, solid phases and gases. Temperature and pressure adjustments of equilibrium constants and Pitzer parameters for the conditions in the reservoirs (up to ca. 200°C and 600 bar) were also added. This database, which, according to the project is called “gebo”, by no means claims to be complete, and is continuously updated (e.g., silicate phases, copper species, cement phases). The “gebo” database, which was extended by the above-mentioned additions, was tested through a comparison of experimental and modelled equilibrium concentrations in the solubility equilibrium, with respective mineral phases, under certain temperature and pressure conditions [8].

Modelling of Water Composition in Deep Aquifers Generic, hydrogeochemical models were developed for five geothermally used deep wells and research drillings of the Northern German Basin (Neubrandenburg, Neustadt-Glewe, Hamburg, Horstberg, Groß Schönebeck), respectively. Hereby it was shown that it is possible to reconstruct main processes in the geothermal reservoir (salt leaching, albitisation, reactions with degradation products of organic substances), in technical systems (corrosion, mineral scaling) and during sampling at surface conditions (gas release) [9].

Modelling of Water Composition in Hot Dry Rock Systems The following processes have to be taken into consideration while modelling water composition in hot dry rock systems:

Issue 04 | 2012

• Temperature and pressure changes during feeding of surface water and extraction of the water generated in the geothermal system, • Reactions of the minerals of the geothermal reservoir rocks induced by feeding of water (e.g., salt solution, equilibration with sulphate and carbonate minerals, ion exchange at mineral surfaces), • Possible mixture of surface water with residual fluids and gases in the geothermal reservoir, • Reactions of water with the material used for construction of the well (e.g., steel pipes, cement).

In case of sufficient retention time in the geothermal reservoir, such processes run until the time that a thermodynamic equilibrium is reached. However, the time dependence of these reactions (reaction kinetics) in a geothermal reservoir is mostly unknown. In addition, reaction rates change, according to temperature. A worst case scenario would be to presume maximum salt dissolution (reaching thermodynamic equilibrium) and a mixture of injected water with residual fluids in the geothermal reservoir. Such a scenario can occur under geological and hydrogeochemical conditions in the deep rock reservoirs of the Northern German Basin. Figure 2 shows the maximum concentrations that can occur during the dissolution of the salt mineral halite (NaCl), according to temperature. The solubility increases with increasing temperature. In case NaCl saturated water is cooled down during geothermal energy generation, NaCl will be precipitated. However, apart from NaCl, there are many more minerals in the reservoirs that have to be taken into consideration in hydrogeochemical modelling. Precipitation of the mineral barite (BaSO4), which is also progressively soluble with increasing temperature, is also often observed. The solubility of barite is much more lower than the solubility of halite and not only depends on temperature, but also on the salt content of the overall solution (Figure 3). The solubility of BaSO4 increases with increasing portion of dissolved NaCl. This behaviour is called “salting in” effect. However, some minerals, like for example celestite (SrSO4) and anhydrite (CaSO4), become less soluble with increasing temperature. The solubility of the mineral quartz (SiO2) increases with increasing temperature, but decreases with increasing salt concentration of the overall solution (“salting out“effect). This differing characteristics

TRANSFER OF TECHNOLOGY of minerals in a natural system and the interference of the various temperature, pressure and solubility effects have to be taken into consideration in hydrogeochemical models, so that predictions of the chemical composition of deep groundwaters and temperature-dependent changes of the water composition are possible.

The following, simple example shows the calculation of chemical composition of waters for a hot dry rock system (temperature of the reservoir: 160°C), using the code PHREEQC in combination with the “gebo“ database. The water brought into the system reacts with the minerals of

the geothermal reservoir rock. It is suggested that rock forming minerals and halite are available as an unlimited phase amount. The alteration of anorthite to albite, the dissolution of sylvine and bischofite are restricted by a limited phase amount. Since sodium containing albite is generated, and the water contains high calcium concentrations, the maximum solubility of halite at 160째C (see Figure 2) is not achieved. Furthermore, the model allows the formation of gases at a temperature of 160째C and a pressure of 500 bar, due to a reaction of the degradation products of organic material. These modelling steps mainly include hydrogeochemical processes, which occur in the geothermal reservoir. The described reaction steps are simulated for modelling in the input file for the PHREEQC programme (Table 1).

Issue 04 | 2012

During the further geothermal energy generation, the resulting water reacts with the steel of the well casing. The corrosion of metallic iron is simulated in the model with a limited phase amount of metallic iron. The high iron contents of geothermally used waters can mostly be attributed to the iron input from the well casing [10]. Hydrogeochemical reactions are triggered by the loss of temperature and pressure at the well head, so that the chemical composition of water again changes through the precipitation of minerals (formation of scalings) and the formation of a gas phase. Table 2 shows the chemical water composition of the injected water, the water in the geothermal reservoir and the pumped water. Since minerals precipitate during pumping of the water, there is a decrease of

TRANSFER OF TECHNOLOGY the corresponding elemental concentrations in the water. The concentration of sodium decreases from 6.0 to 5.4 mol/kg H2O, chloride concentration decreases from 10.5 to 10.0 mol/kg H2O. The amount of precipitated minerals can be calculated from the differences in concentration. The high amount of halite precipitated due to the reduction of temperature (approx. 600 mmol/kg H2O, corresponding to approx. 35 g NaCl/ kg H2O) may lead to a significant reduction of permeability in the reservoir (decreasing porosity) and the technical systems (e.g., pumps). The calculated amount of precipitated Ba-Sr-sulphates (modelled as “solid solution“) is approx. 1.7 mmol/kg H2O, which is significantly lower than halite. The introduced model can be adapted to the actual conditions of the respective geothermal plant (e.g., by considering the ion concentration in the injected water, temperature and pressure concenrations of the geothermal reservoir, and conditions of sampling). Due to the fact that no measured data are available for geothermally used waters from hot dry rock systems, the modelling results can currently not be checked with

real data. It is noteworthy that the exact determination of element concentrations in waters that have reached halite saturation or oversaturation depending on the reservoir temperature is a challenge in chemical analytics, and has to be carefully planned before sampling. Furthermore, it should be taken into consideration that for highly saline waters, the entry of concentration into the PHREEQC input file has to be done in the unit mol/kg H2O.

Summary Hydrogeochemical modelling of geothermally used waters can significantly contribute to the understanding of processes in the geothermal reservoir and in technical plant components, and should therefore be done during the planning phase of geothermal energy generation plants. In order to improve modelling results, it is necessary to further complete and continuously evaluate the “gebo” database, as well as to include kinetic processes. The newly developed “gebo” database can also be used for other hydrogeochemical modelling applications (e.g., oil field waters, sea water evaporation).

(Geothermal) Drillings and Environmental Protection ermany can look back to a tradition of over 150 years of drilling of production and G exploration wells for mining and water supply.

by Dipl.-Ing. Waldemar MĂźller-Ruhe President | GtV-Bundesverband Geothermie e.V

The pertinent provisions for legal protection, which have been in force for the past 30 years, are also relevant for geothermal wells, since geothermal energy is considered a resource in terms of mining law.

Mining law owners agree with all concerned authorities, corporate enterprises, public stakeholders and other institutions on an operations plan procedure and on a course of action to implement a drilling project. This course of action takes into consideration goals of environmental protection, as well as safety and health aspects. The anti-pollution law adequately considers all effects on the neighbourhood, the surroundings, as well as protection of the underground. Legitimate requests of concerned parties are incorporated as obligations into the operation plan, and are to be followed by the mining company and the boring contractor. Hereby, the main focus of attention is on protection of ground water during drilling of the respective borehole section. Thus the unwanted vertical exchange of different ground waters, as well as gas flows and unwanted pressure-related fluid flows (Artesian, CO2, hydrocarbons) can be prevented. The attached passage of an exemplary operation plan and its conditions provide an impression about the extent of ground water protection rules. As evident from the rules, ground water protection already starts with the setup of the drilling site, since no hazardous material should infiltrate the underground during the operation of the drilling rig. The appendix â&#x20AC;&#x153;drilling site constructionâ&#x20AC;? provides an overview over this quite complex construction. After the setup of the drilling rig on the drilling site, setting of the conductor tube is done with the first drilling section.

TRANSFER OF TECHNOLOGY Drilling and plant construction

1. Surface String of Conductor Pipe Drilling equipment Since the author assumes that not all readers are familiar with drilling rigs, information on the structure of a drilling rig and its functional components, as well as pictures on drilling methods and some drilling tools are attached. In order to start deep drillings in a controlled manner, as well as to lastingly protect near-surface and usable ground water horizons, a so-called conductor pipe (steel tube Ă&#x2DC; 500 â&#x20AC;&#x201C; 750 mm) with a total length of between 20 to 60 m is inserted into the underground. In recent years the conventional driving has been replaced by a vibration-free, piped rotary drilling method with a large calibre rotary or grab excavator rig with a casing machine.

Thus, the first ground water horizons are lastingly protected and securely locked during further drillings.

2. Drilling Fluid Application/Safety In drilling of deep wells there is a possibility of encountering gases or fluids, and drilling experts have been trained to deal with that. This is the reason why the drilling site is equipped with relevant shut-off devices (Blow-Out Preventer â&#x20AC;&#x201C; BOP), Scheme of Rotary drilling system

Hereby, during the loosening and outlet of the drillings, parallel to the operations the borehole casing is entrained and sunken to the planned depth. The smaller conductor tube is inserted into this pipe. Cementing pipes are attached to this steel pipe, through which cement slurry is pumped from below to the ground level. During this cementing process the auxiliary piping is removed, so that a complete, leak proof closure between conductor pipe and borehole wall is created.

which are connected securely and pressure tight with the armature tube. The drilling of the second section and the consecutive fitting of the axial conduit is consecutively shown. Here, it should be noted that drilling fluid also significantly contributes to safety (also applies to sampling): Apart from its various tasks of cooling the drilling equipment, slugging out the cuttings and contributing hydraulic auxiliary energy for drilling and power generation, the main task of the drilling fluid is to furnish the drilled hole with a semi-permeable, elastic membrane, the so-called drilling mud cake, which prevents the exchange of drilling fluid into the ground water. In addition, it counteracts swelling, which leads to narrowing of the drilling calibre and difficulties in pulling out the drill bit. The supporting and gel-forming (thixotrope) effect of the drilling fluid is achieved through bentonite. The prevention of swelling characteristics of clays and sulphate rocks is achieved with substances that are applied in food industry as coagulant, as wall-paper paste, or in agriculture (potassium carbonate) for soil improvement. After the

drilling has reached the desired depth, the cuttings are circulated out and a drilling fluid that is fully cleaned from cuttings is brought in. Then the drill string is installed, and with the help of geo-physical measurements, among others, the drill hole volume is calculated, in order to calculate the amount of cement needed. After these preparations, the armature tube (Ă&#x2DC; 340 â&#x20AC;&#x201C; 473 mm), which is equipped with centering devices, can be installed.

TRANSFER OF TECHNOLOGY Due to the fact that liquid cement slurries are much heavier than the drilling fluid in the conductor pipe/ drilling, the upper pipe is equipped with two return valves. The upper valve is installed and secured in a grouting pipe. The previously calculated amount of cement, plus a safety margin is pumped through these drill rods. The cement flows through the valves into the concentric annulus, from there it flows out and rises to the surface. The first evidence for the success of cementation is the check against homogeneous density. Amount and density of the cement are constantly monitored; additional measurements are carried out to determine cementation data, the adhesion of the cement at the borehole wall and at the piping, as well as the complete borehole sealing, i.e. gas proofness. After hardening of the cement, drilling is continued with a smaller bore diameter. However, at first the above-mentioned return valves are drilled out and drilling is only deepened for a few meters. In order to prove the tightness at the mull shoe, the raises in the rodding and in the annulus are closed, so that the drilling fluid can be pressed in, until a certain allowed value of pressure is reached. Special cases of drilling operations that can occur through squeezing inflows, but also through low-pressure horizons, can be dealt with by respective increase or reduction of drilling fluid density. Drilling fluid losses are counteracted by application of emplastics and/or cementations, so that the drilling can be conducted under controlled conditions. The mechanical sealing of such

zones with swelling or hydraulically inflatable steel pipe elements (ECP â&#x20AC;&#x201C; External Casing Packer) would even be another option. Usually, after generating the borehole section 2 with permanently tight installation of the armature tube, two bore hole sections, which are lined and secured with the so-called technical armature tube, follow. The reservoir is reached from the second armature tube. In order to shape the biggest possible area of access to the expected water, geothermal wells in the carrier rock are drilled as highly inclined to horizontal. Since high drilling fluid losses, i.e high permeabilities are expected at later stages, the highly dense drilling fluid is exchanged with water, in order to keep the supporting structures open. Up to now, attempts to drill in the reservoir with a gaswater mix in the unbalanced method have not brought the desired results. Causal studies are still under way.

Reservoir Development in Deep Geothermy and Effects on the Environment, including simulations and Frac Methods, in Accordance with Environmental and Ground Water Protection As already explained, the priority in deep drillings is the protection of ground water in various horizons and depths.

Nevertheless it is very important that planning engineers, as well as the drilling company take into consideration all other possible environmental effects of a drilling programme, which usually consists of two drillings. Neglecting one or several aspects of environmental impact can lead to considerable delays, if not the failure of a basically good project, particularly with regard to acceptance of the surrounding population. In this regard the information received from the critical population in various construction projects can be used as checklist for self-evaluation. Following please find a table, which has been developed in order of the steps usually taken and their feared environmental impact, with the exception of groundwater protection issues, which have already been discussed.

• Construction measures for setting up a drilling site • Piling operations for the conductor tube

Expected Impairments, based on the Federal Immission Control Act One of the most frequent fears of affected communities and residents is related to the possible exposure of noise from the construction site, including all incidental transports and related operations. In this regard it should be noted that drillings, including geothermal drillings, have to be conducted in continuous day and night operations, seven days a week, in order to secure stability of drilling. Nevertheless, it should be noted that in past years, it has been possible to implement deep drilling projects in many locations with quite sensitive neighbourhoods (Spas, Campus Aachen, Arnsberg, GeneSys Hannover, Unterschleissheim), without complaints from the affected residents. This was achieved through the cooperation of all involved parties and with careful noise control programming, where only equipment was used, which was noise reduced according to the newest state of the art. In addition, it is possible to implement noisy operations during the daytime.

Example of a grid noise map of a noise-optimized drilling plant with a 15 m noise protection wall

The most important contributions have been efforts to minimize noise, which have eliminated or minimized impulse noises (e.g. Pipe Handler â&#x20AC;&#x201C; abandoning finger board). Within this category falls the modification of energy supply of diesel-electrical generators with line current. This procedural step has led to the fact that deep drillings have even been possible in immediate surroundings of high quality residential areas, i.e. at a distance of approximately 70 m.

Construction Measures for Construction of Drilling Site Usually, such operations are only conducted during the day. Apart from small vibrations during operations to compact the soil in preparation for ground work, they do not entail any further impairment for the environment.

Issue 04 | 2012

In case the conductor tube is planned to also be installed in drilling rig preparations, care should be taken to use the vibration free, piped dry drilling method. In this method the smaller conductor pipe is installed after reaching the planned casing depth, and the annulus between pipe and borehole wall/auxiliary piping completely cemented from bottom to top. The auxiliary piping is drawn parallel to the increasing cement mixture. As soon as the cement mixture has reached the ground level or the bottom of the rig cellar and the temporary drill pipes are fully recovered, the cement can set.

Heavy Good Vehicle Traffic, Frequency After completed setup of the drilling site, i.e. after hardening of the concrete foundation, deep drilling equipment is set up. The delivery of the required components is done during daytime for a period of approx. 8 days with approximately 80-90 normal trucks. 5 of these transports fall into the heavy load category.

www.advanced-mining.com

TRANSFER OF TECHNOLOGY The assembling/dismantling of equipment, which takes approximately 10 days, is only done during the day and with mobile hydraulic cranes. The above-mentioned shows that transports to the site do not pose any additional burden on the public infrastructure. In case there is a need to construct separate roads to access the drilling site, they are built according to static and trafficrelated requirements. All other transports needed during the drilling operation, are one-time transports which do not create any disturbance. This also applies to the trips needed for changes of shifts, which are done with passenger cars and do not pose any inconvenience.

Day and Night Operations In order to secure the structural safety of a deep hole, it is necessary to operate on 7 days a week for 24 hours, since the borehole is only stabilized by the applied drilling fluid. The issue of sound protection has already been dealt with earlier, under the aspect of “night operations”, only the concern regarding day-like illumination of the neighbourhood is dealt with in this section, as it can interfere with the sleep of the residents. A sufficient illumination of the drilling site, particularly of the working areas, is of essential importance. The reason is that this is the only way to maintain work safety at a high level, which is one of the basic goals of responsible drilling companies – avoiding incidents and accidents. However, there are clear requirements for the area outside of the site, i.e. the light should not have any illuminating or dazzling effect. Furthermore, according to the new guidelines, care should be taken that the light temperature should be chosen in a way that nocturnal creatures do not find it attractive. This is being achieved with a pre-selection of appropriate illuminants.

Land Requirements – Land Usage Apart from an access road of approx. 4.5 m width and the required length, the land requirement for the drilling site is approximately 5,000 to 7,000 m². While the boring site is selected based on the combination of the underground situation and the location of usage (power plant), the

Issue 04 | 2012

goal of minimising costs calls for the shortest connecting routes to the available infrastructure. In case the abovementioned area is to be covered by the power plant, it will determine the actual land requirements. However, it should be well below the above stated. In case the power plant is not built at the drilling site, only a permanently usable area of 10 - 15 %, i.e. 600 – 1000 m² remains for future measurements, tests, or pump installation. Unused land will fully be recultivated and will be returned to the original owners, in line with previous agreements.

Disposal, Waste Management and Residue Treatment All material delivered to the drilling site is catalogued, documented and its usage or whereabouts is determined. In case of relevant expendable material, hazardous substances indexes are available, in which the risk potential, measures for hazard control, proper handling of these substances and verifiable disposal routes have to be proven. The safety officers of respective drilling operations coordinate the acquisition, supply, application, as well as the disposal with drilling teams, suppliers, service companies, as well as with the contracting authorities. This includes a complete, reproducible and transparent documentation. Most of the disposals are household waste, hazardous waste and residual materials, such as borehole cuttings, used drilling fluid, but also cement residues. The material is sent to its final destination on a depository by certified and accredited waste management companies.

Odors Normally, drilling operations and surrounding work do not generate any unpleasant odor. In connection with avoiding noise, the issue of changing diesel generators to electrical power supply has already been recommended. This change also plays an important role in avoiding unpleasant odor. However, despite the application of modern engine technology and application of filters and catalyzers, unpleasant odor of burnt diesel cannot fully be avoided in cases of adverse weather conditions and

www.advanced-mining.com

TRANSFER OF TECHNOLOGY in case of proximity of housing. One remedy would be electrical operation with the power supply from a public energy supply. Thanks to the high security of supply, an application of emergency power supply has to date not been necessary.

Dust Formation Usually, activities related to civil engineering operations can only lead to dust formation, when applying and compacting sand. This problem can be addressed with dust attachment measures through addition of water. The previously mentioned delivery transports also do not produce dust on paved access roads. Some products delivered during the drilling operation, like fluid additives or cement, which are in form of dust, are either delivered in silos or in Big Bags and applied in the mixing phase, so that no dust is formed. Furthermore, the personnel (drilling and service) are trained with regard to security. The author is not aware of any incident with regard to dust formation.

Nature Conservation â&#x20AC;&#x201C; FHH â&#x20AC;&#x201C; Forestry Needs Important issues in this regard are mentioned in preceding discussions by public stakeholders, and are reflected in collateral clauses of the operating plan licence (e.g. transfer of the drilling site out of breeding seasons or times, or rest times of migratory birds).

Measures to Improve Efficiency After drilling through the reservoir and the borehole cleaning, it is time for first production tests with the help of output pumping tests. In case the inflow from the reservoirs rocks, the malm lime, i.e. the corallian limestone is not sufficient; the awarding authority usually reverts to a simulation of this section. The goal is to improve and widen the route to an extent that an access to the spacious reservoir is achieved. Since this rock can be dissolved with acid (like it is done with limescale in the household), after careful planning and taking respective safety measures, 15% hydrochloric acid are pumped into the reservoir. While flowing through,

Issue 04 | 2012

the acid dissolves the fillings in the corallian limestone with the already mentioned chance of an improvement in inflow. The drilling is included in this phase. As a result of the process of disintegration, carbon dioxide is generated as a residual product, which can be released in a controlled manner after some time and with relevant safety measures. Consecutively the drilling is rinsed with water. The backflow is carefully measured, whereby the pH value offers safety information. In case data below the neutral value (7) are recorded, gypsum is added to the backflow as a neutralizer, so that the mixture is stabilized and can safely be disposed of, if there are no plans to use it otherwise. Further production tests then often prove the desired success. With this, planning of the power plant can start.

Frac works Up to now only hydrothermal reservoir exploration has been discussed, in which the basis of planning are hydraulically available routes. This has not been the case in petrothermal energy generation projects, which have not yet been implemented in Germany. Hereby it is assumed, that in respective depths the required temperature (>130, better 175Â° C, which means depths of >5000 m) is available, however the rocks are dry. The question whether the rocks are compact, or whether they are cleftet, but dry formations can only be answered by drillings. After completion of the drilling work it is possible to determine, whether permeability exists or can be created, and whether this can lead to an economically operated heat exchange. In order to create a spacious heat exchanger, a crack system has to be generated, through which water can flow in sufficient amount/ time unit and with corresponding time for energy assimilation for the power plant operation, so that an economically sustainable system can be developed. In the current discussion on unconventional gas reserves, the generation of such a crack system is currently being demonized by the word Fracking, since reports from the US on gas deposits and water pollution were adopted without checking. In addition, compared to the situation in the US, the German water supply, which is fully available nationwide and has a completely different

www.advanced-mining.com

TRANSFER OF TECHNOLOGY structure, in conjunction with the German legal framework in this regard – Mountain-, water-, environment- and chemical – laws- are practically irrelevant for the needed discussion on new gas reserves in Germany. The rocks for petro thermal energy generation are dry, as apparently ground water flow has not reached them. Several thousands of meters of rock layers, which act as barriers, prevent the flowing through. Ground water, as possible drinking water reserves for future generations, is thousands of meters away from these horizons, and even in case of spa- or mineral water reserves there are a few thousand meters in between. Furthermore, the generation of cracks in solid rocks follows a technique other than the one used for crack generation in sediments like clay or shift for the purpose of gas extraction. Currently the geothermal energy industry assumes that a Frac fluid, which consists of water, sand grains and possibly gelling agents for development of bearing capability, does either not need other additives for prevention of corrosion or bacterial contamination, or only needs them in very small amounts. Such can be products that are borrowed from the food chemistry. Before any discussion can start on these, petrothermal energy projects need to be implemented in the first place.

If the energy transition - with the replacement of more than 60% of energy supply on the basis of fossils- is to be successful, it is important to consider not only the risks, which evoke fundamental fears in some, but also consider the opportunities of shifting to renewable energies as local, decentral energy sources. In this connection the consequences of this lack of action, which is forced upon us, should also be thought of.

“Energy-recovery System“ for Continuous Conveyors

by Dipl.-Ing. Dr.mont. Michael Prenner Chair of Conveying Technology and Design Methods University of Leoben | Austria

Materials, which were transported by continuous conveying systems, have partly, depending on the speed of travel, a High - energy content. At transfer points from one conveyor to another or at discharge points from a conveyor to a storage area or to a discontinuous conveying system, it is possible to recover most of this energy and return it to the conveying system. At the chair of Conveying Systems and Design Methods at the University of Leoben an energy recovery system, which allows the recovery of a large percentage of the kinetic and the potential energy of the transported material, was developed. This energy could be returned to the conveyor in the form of electrical or mechanical power. The functional principle of the so called „Solid State Material Driven Turbine“ could be already confirmed by experiments at a transfer point of a belt conveyor test rig for bulk material. This simple test facility, which is shown in figure 2, allows an energy recovery of about 80% of the kinetic and potential energy of the bulk material. The energy is returned to the conveyor in the form of mechanical power. The experimental test results could also be confirmed by discrete element simulations. A patent for the technology was applied for (patent pending no. M 1410 GB).

Introduction

Energy Content Of Moving Solids

Solid state materials, like any kind of bulk materials as well as suitable piece goods, which were transported with a continuous conveying system, have a highenergy content depending on the mass flow and the conveying speed. At transfer points from one conveyor to another or at discharge points from a conveyor to a storage area or to a discontinuous conveying system, it is possible to recover most of this energy and return it to the conveying system.

The energy content of solids, which were transported on continuous conveying systems, depends on the mass flow and the conveying speed. At transfer or discharge points the solid materials increase their energy content because of the height of fall depending on the conveying conditions. A large part of the kinetic energy due to the conveying speed and the potential energy relating to the drop height of solids could be recovered to the conveying system by the help of a suitable energy recovery system.

At the chair of Conveying Systems and Design Methods at the University of Leoben an energy recovery system, which allows the recovery of a large percentage of the kinetic and the potential energy of the transported material, was developed. This energy could be returned to the conveyor in the form of electrical or mechanical power.

Figure 1 shows the energy content respectively the content of power of an belt conveyor with 10000 t/h mass flow and 5 m/s belt speed. The graph in figure 1 depicts the substantial content of power (energy) of the moved bulk material. With conventional conveying systems this energy will be „thrown at a stockpile“ for example or will be converted into wear, heat, etc.

Solid State Material Driven Turbine At the chair of Conveying Systems and Design Methods at the University of Leoben an energy recovery system for continuous conveying systems was developed. The so called „Solid State Material Driven Turbine“ could be used at transfer or discharge points to recover the energy, which is contained in the moving solid materials to the conveying system. To recover the energy (power) back to the conveying system an alternator or mechanical linkage with the conveyor could be used. In the course of a feasibility study a first prototype of a simple „Solid State Material Driven Turbine“ was built and functional tests were made. Figure 2 shows the experimental setup of a first „Solid State Material Driven Turbine“. For the first tests a relatively simple and easy to produce geometry of the „Solid State Material Driven Turbine“ was chosen. The turbine was installed at a transfer point from one belt conveyor to another. The used bulk material (metal - crushed stone) was discharged from the first conveyor into the rotating turbine. At the outlet area of the turbine the second conveyor beneath the turbine picked up the bulk material and moved it away from the turbine. The turbine converts the kinetic and the potential energy of the moving bulk material into

mechanical power. To transfer the mechanical power to the conveying system a chain drive was used. This chain drive connected the turbine directly to the drive pulley of the discharge conveyor belt (figure 2). With the help of this energy recovery system the absorbed power of the discharge conveyor could be significantly reduced.

To realize a maximum power output a relatively big turbine was chosen in relation to the conveyors. This was necessary because of the small mass flow. The turbine should also be applicable for considerably higher mass flows.

Test Results Several measurements with different parameters were done.

TRANSFER OF TECHNOLOGY Figure 5 shows the power saving because of the turbine at an increased mass flow of 28.13 kg/s. In that case the power saving was 152 W and corresponds to a reduction in the absorbed power of about 16.3 % (reduction in the absorbed power from 928 W to 777 W). Out of the moving bulk material it is theoretically possible to recover 195 W of power because of the stored energy (drop height of 0.39 m and a discharge speed of 2.5 m/s). According to this theoretical possible power an efficiency of about 78 % for a mass flow of 28.13 kg/s could be calculated for that case.

The measurements show that, even with a simple geometry of the turbine, it is possible to recover a large amount of the stored energy of the moving bulk material. The efficiency difference between the two measurements with different mass flews is a result of a slight belt misalignment of the discharge conveyor. The belt misalignment causes fluctuations of the absorbed drive power of the discharge conveyor drive. A second reason for this efficiency difference is the undesired contact between the bulk material on the second conveyor and the turbine at the outlet point of the turbine.

TRANSFER OF TECHNOLOGY To verify the results of the measurements and to optimise the geometry of the „Solid State Material Driven Turbine“ discrete element simulations (DE - simulations) have been carried out.

DE - Simulation Of The Turbine Prototype Figure 6 and figure 7 show the results of the DE simulations of the test turbine. Figure 9 depicts the torque of the turbine at two different speed levels. A mass flow of 28.125 kg/s was used for the simulations. Running the turbine at a speed level of 0.3351 revolutions per second (corresponds to the speed of the experimental setup) a power output of 163 W could be calculated. With the same basic conditions a power output of 152 W could be measured in the experimental tests. The power output in the tests and in the simulations is almost equal. The difference of 11 W between the tests and the simulations results from the fact that it is not possible to consider the losses due to the bearings and the chain drive

used. A little measuring inaccuracy also occurred because the power output of the conveyor was measured over the power input of the drive motor. The simulation also shows that the power output depends on the rotation speed of the turbine. There is an optimal operating point of the turbine (gear ratio: pulley - turbine), which has to be determined with further simulations and tests.

DE - Simulation Of A Reclaimer With A “Solid State Material Driven Turbine“ Because of the realistic simulation results an attempt was made to implement such an energy recovery system into a reclaimer in a simulation. For this reclaimer a couple of different turbine geometries were installed at the transfer point boom belt centre chute. In the following two simulations two different turbine geometries will be shown. The geometry and the performance data of the turbines are listed in table 1.

TRANSFER OF TECHNOLOGY Fig 8: Turbine small

“Turbine Small“ With 2,36 m Diameter And 2 m Width To transfer a maximum of the kinetic energy of the moving bulk material into turbine power, it is necessary to contain as much as possible of the bulk material in the turbine buckets. Ideally the slowed down bulk material should be totally contained in the mashed turbine buckets and should be totally discharged at the lowest position of the turbine buckets. To transfer the kinetic energy into power it is also necessary to slow down the bulk material in the turbine buckets. To get out the optimal speed difference further analysis had to be done. With the turbine which is shown in figure 8 it is not possible to contain the whole bulk material in the turbine buckets. A larger turbine would be necessary.

A larger turbine has a few disadvantages. The rotating masses, the torque and the centrifugal forces will increase significantly. If a technical development of such a turbine is possible it is necessary to do further analyses. It must be ensured that there is no significant increase in investment costs of a machine with a „Solid State Material Driven Turbine“ due to the energy recovery system. Otherwise there will be no economic advantage. The small turbine has a power output of 40 kW at an efficiency of about 48 % (mass flew = 3135 kg/s).

“Crossflow Turbine“ With 3,8 m Diameter And 2,2 m Width To contain the specified mass flow of the reclaimer in the turbine it is necessary to use a more complex turbine geometry. In this case a so called crossflow turbine (figure

9) would be the best choice. By using that kind of turbine no bulk material will leave the turbine blades in an untimely fashion because of the centrifugal force. Only when the blades are dipping into the bulk material stream a small amount of bulk material will leave the influence zone of the turbine. By using a baffle plate this small part of the bulk material could be returned into the turbine.

To test the function of such an energy recovery system in practice a „Solid State Material Driven Turbine“ will be installed at a facility in the area of limestone in Austria. The operating conditions in this case are relatively critical. The bulk material (limestone) has a grain size distribution between 10 % < 10 mm and 10 % > 70 mm with a maximum particle size of 300 mm (figure 12). For this kind of bulk material, critical wear conditions at the turbine should be expected. Furthermore, fine material could stick in the turbine buckets. This could also affect the function of the turbine. These critical conditions should give more insight into the limits of application of such an energy recovery system.

The vertical height between the axis of the turbine and the pulley is about 1.5 m. It is important that the turbine does not disturb the running operation of the facility. The size of the turbine and the associated power output is limited because of the existing installation space. The use of a wheel loader instead of the belt conveyor for feeding the crusher has to be ensured (figure 13).

DE Simulation Of The “Limestone Turbine“ The discrete element method (DEM) was used for designing and optimising the turbine. With the aid of the DEM it was possible to find out the best position of the turbine buckets and the turbine itself. Also the optimal number and design of the buckets could be acquired for the existing conditions. The result of the DE - simulation was a quite realistic statement about the torque path of the turbine (figure 15). This torque path could be used for calculating the power output and for dimensioning the components of the turbine.

From that value the losses due to the used traction drive, the bearings, the drag, etc. have to be subtracted.

could make a small contribution to reduce the energy consumption of conveying systems. In this case the energy which could be recovered is freely available. At the present time this energy is thrown onto a stockpile or is converted into plant wear.

The available space unfortunately requires an oncoming flow or turbine rotation against the direction of rotation of the drive pulley. Therefore it is necessary to install a reversion of rotation of the torque. This requires an increase of the engineering effort in combination with an increase of the losses of the energy recovery system. Due to the fact that this turbine is a test turbine, which should afford more information about the limits of the applicability of such a system, the amortisation time is not taken into account. In principle turbines with a low power output are less cost-effective than turbines with a high power output. The development and engineering effort in relation to the energy output is much higher for small turbines with low power output than for turbines with a higher power output. In the future an amortisation period between one and two years should be realized.

Conclusion First tests have confirmed that it is possible to recover energy from moving bulk materials. The so called „Solid State Material Driven Turbine“ could be used at discharge or transfer points to recover this energy, for example, to the conveying system. It is possible to realize a high effectiveness with a relatively simple turbine geometry. For an efficient use of that kind of technology it is necessary to use simple geometries and constructions. The turbine buckets are exposed to strong wear depending on the bulk material used and have to be lined with removable wear plates. This is much easier and more economic if the geometry of the turbine buckets is simple.

Practical Examples on Optimizing Function and Reliability of Pneumatic Conveying Plants

by Dipl.-Phys.-Ing. Klaus Schneider KS-Engineering GmbH Köln | Germany

The goal of this oral presentation is to offer selected examples to the working engineer in practice, showing the possibility of optimizing existing pneumatic conveying plants with simple means. The following cases of application are presented: • Adapting and optimizing air supply for vacuum and pressure convey-ance • Influence of cabling on the plant performance, shown at the example of enlargement of a cross section • Minimizing of abrasion with simple measures • Optimizing of pressure vessel conveyance • Influence of material characteristics (like for example flow properties) on pneumatic conveyance • Minimum speed in pneumatic conveyance and its influence on plant performance

Vacuum Conveyance –Amount of Air in Pneumatic Conveyance and Segregation of Solids in Cyclones

As remedial measure, a bypass opening (fig. 1) was added in the conveying pipe of the cutting mill, which allowed for an air inflow that was regulated with underpressure, leading to a complete material separation.

In this section, the importance of a properly designed air supply will be de-scribed, using the example of pneumatic transport of foamed materials. In order to do so, large pieces of foamed material are cut into several sizes (qualities) in a cutting mill, with the help of variously sized perforated sheet inserts. The cut foam pieces are drawn in by a connected vacuum pump and led to an arrangement of silos. If appropriately connected, all silos of this arrangement can be filled with a total of 20 product silos. The segregation is done by a cyclone, which is set up on the respective silo top (see fig. 1). Shortly after the start of operation, the cyclones were completely blocked, and it was not possible to continue operation, since all material was separated in the downstream control filter. Very soon it became clear that the carrying air before the cyclone was insuffivient and therefore the desired centrifugal separation was not possible. The air inflow over the cutting mill (particularly with coarse material) was insufficient. As a result, the foamed material was pressed through pipes to the cyclone with low speed. Due to the lacking carrier air at the cyclone, no rotation flow was generated, there was no segregation and the material blocked the cyclone.

Grading of Piping in Pneumatic Conveyor Pipes

Issue 04 | 2012

Pipe expansions serve to adapt the speed in pneumatic conveyor pipes and are meant to keep air speed within certain limits over the conveying distance. The preferred location for such adaptations is the vertical conveyor pipe, since it is “less sensitive” to such changes than the horizontal conveyor pipe. However, expansions should not be positioned in horizontal pipes, immediately following a direction change, since the material slows down during the direction change. An expansion at this location entails the danger of a blockage. The expansion should be positioned in a way that a sufficiently long acceleration distance is available after the direction change. The following figure, which is taken from a publication of Weidner (1), shows the deceleration of solids in bendings. The dotted line as limiting curve, applies to the radius-less redirection.

TRANSFER OF TECHNOLOGY Fig. 3: Ball recirculation with direct expansion of the pipeline

Fig. 4: Deceleration of solids in pipeline in bendings

It is for this reason that the expansion from 60 to a bore of 80 mm should logically be done approximately 12 m downstream, and the additional acceleration distance (of approximately 30 -50 dli) should be used for the re-acceleration of the solid to ce = 16 m/s after the bending and before the expansion of the cross-section.

Pressure Profile in Pneumatic Pressure Vessel Conveyance The pictures show pressure profiles in two pressure vessels of the same type and size, having similar pipe lengths, pipe routings and material (boiler ash) and positioned in the same garbage incineration plant. Nevertheless, they show very different emptying times, pressures and pressure profiles. On one hand this can be attributed to programming of control procedures, on the other hand it is due to the varying amounts of air for conveyance.

Inlet velocity ce [m/s]

For example, in case solids enter bendings with a speed of approx. ce = 16 m/s (in an air speed v of 20 m/s, this corresponds to a c/v ratio of 0,8), they leave with only ca = ca. 9 m/s. In case the diameter is increased from 60 to 80 mm, the air speed, which is the propelling force, abruptly drops from 20 m/s to approx. 11 m/s. This means there is a high risk of blockage, as the â&#x20AC;&#x153;slowerâ&#x20AC;? air insufficiently accelerates the solids.

Minimum Speed in Pneumatic Conveyance of Sandy Solid Material This example describes pressure vessel conveyance from boiler ash (coarse) from circulating fluidized bed combustion over a total length of 350 m, however, it can apply to any sandy material to be conveyed. During the operation, pressure impulses in conveying pipes were repeatedly observed, which even led to tearing of joists at the silo. Typical grain size distributions are presented in figure 8. Figure 9 shows the classification of these solids in the so-called Geldart diagram. (2). These extreme pressure fluctuations can clearly be seen in the attached measuring tape (Figure 10).

Fig. 10: Recording of pressure pattern at two points of the pneumatic conveyance, distance approximately 5 m

a. The pressure at measuring points rises with increasing conveyance time. The reason is that there is a repeated generation of plugs at the beginning of the pipe, which slide through the pipe. This leads to a quick increase of the entire pressure level. b. The increase in the amount of air in the pipe leads to a fading of plug activity in the conveyance pipe. c. Single plug formations can also be seen in the measuring route.

• The conveyance time per vessel was reduced by approximately 25%, i.e. flow rate was increased in the same degree.

Generally it can be said that with sandy material to be conveyed (Geldart classification “B”), a minimum speed needs to be ensured at the beginning of the conveyance pipe, thus achieving a smooth and plug-less conveyance.

Conclusion: The implemented changes not only led to achievement of the goal of optimization, but the goal was exceeded!

Pressure Vessel Conveyance (Flow Characteristics under Pressure) DPressure fluctuations in pneumatic conveyance can have other reasons than the ones described in chapter 4. In principle, the pressure vessel is a “silo” and the material stored follows the same laws of flow and friction characteristics, as in storage silos. What makes matters worse is that, in case of one sided feeding of “upper air” in pressure vessels, the material is compressed and there can be further compaction and impairment of the outflow. Therefore a fluidization and, if needed, a targeted loosening of material in the pressure vessel is important in case of fine and super-fine solids (Geldart category C and partly category A).

The figures 13 to 15 show the flow and conveyance characteristics of quartz sand, quartz dust and lime hydrate in an acrylic glass container. The conveyance pipe vertically leads upwards from the center; a ring loosening (through which

As long as the speed is high enough, the “level” of quartz sand (fig 13) evenly sinks; the pressure in the conveyance pipe stays even and on a constant level. As already mentioned in chapter four of this presentation, In the Geldart classification, Quartz sand is a “B” material. In finer quartz dust (figure 14), the surface is less even than with more coarse quart sand, and ascending bubbles can be seen. Nevertheless the delivery pressure remains stable. Quartz dust is an “A” material in Geldart classification. The pressure and flow rate fluctuations in lime hydrate, which is a real Geldart “C” material, are particularly grave. The formation of cavities and channels through the entire material column can be seen.

Conclusion: The quality (consistency) of conveyance under pressure always relies on the material. In case of very fine and most fine material to be conveyed, care has to be taken to ensure an even fluidization resp. flow characteristic.

Conveyance of Lime Hydrate in Thin Stream Lime hydrate is very fine material and tends to form crusts in pneumatic conveyance plants, particularly in steel pipes. The crusts, however, are composed of limestone, ie. Calcium carbonate. This crust formation only occurs with low loads and high speed of solids, like it is usually the case with lime hydrate as sorbents in environmental engineering; in case of high loads and low speed this effect is seldom observed and in case it occurs, it is minor. How is this possible? Tests have shown that chemical reactions occurring in steel pipes and on hard surfaces are the trigger for this phenomenon.

TRANSFER OF TECHNOLOGY • Discontinuous silo discharge ((→feed tank) • Silo discharge with appropriate support (e.g. sprung floor)

Lime hydrate “ages” by the carbonation reaction Ca(OH)2 + CO2 → CaCO3 + H2O

• Dosage and conveyance parts should be matched

This is a spontaneous reaction and can also be triggered through the impact of lime hydrate particles on a hard surface (steel pipe, in particular bendings). The characteristics of lime hydrate change as follows: • Fluidity is reduced • Moisture content increases, material becomes “sticky” • Tendency to form crusts increases

Alterung wird begünstigt durch: • Air exchange (silo open) – fresh CO2 is constantly supplied

Conclusion: Under certain circumstances, some material to be conveyed shows unusual characteristics. Lack of knowledge about this fact can lead to complete failure in pneumatic conveyance. In the current case, laying of rubber hoses or other flexible material is the right solution for pneumatic transport. On the other hand, the highly active lime hydrate should not be stored in the silo for too long (less than 4 weeks), in order to counteract the mentioned phenomena.

• Time • Reactivity (determines the eligibility al sorbent ⇒ is continuously increased in optimization processes

Conclusions for the operator/planner with regard to material: • Material should be fresh upon delivery (certificate?) • Storage space should not exceed storage time of 2 weeks • Addition of carbon dust (5%) or carbonate (10%) increases the ability to be conveyed (flow characteristics, sieving grain)

Conclusions for the operator/planner with regard to setup/equipment: • At least the silo cone of a storage silo should be encased and heated

TRANSFER OF TECHNOLOGY Adjustment of Air Volumes in Ventilators In case ventilators or side channel blowers are used to generate air, the right choice of the operating point for pneumatic conveyance is a decisive factor. As shown in figure 17, the parabolic characteristic system curve and the concave characteristic curve of ventilator meet in the so-called operating point. In case there are changes in the characteristic system curve, the operating points shifts to the right or to the left. The interaction of the characteristic system and blower curve in pneumatic conveyance plants is shown in figure 18, with the example of a pneumatic conveyance plant for scrap wood.

This danger is more present, if one works with too much of “design safety”, or in case there are plans to convey various amounts (like shown in figure 18). Here the blower has to be regulated (e.g. by FU or air regulator), so that the air flow is limited. In practice this important relation is often missed, and it is only after considerable damage that it is found to be the cause.

Fig. 17: Examples for characteristic curves of plant and compressor

It is evident that, with decreasing flow rate and corresponding decreases in pressure, the intersection between characteristic system and blower curve is shifted to the right, i.e to higher volume flows and also to higher speeds. The wear also increases disproportionately.

The presented examples are intended to illustrate that simple considerations and knowledge about fundamental correlations can surely avoid damage of pneumatic conveying plants, and their optimization can easily be done. Not so long ago, engineers of VDI have published a VDI guideline (VDI 3671), in which producers and operators of pneumatic conveying plants can make arrangements regarding material characteristics and systems engineering, which make it easy for both parties to professionally setup and operate such plants.

New Technology For Creating Slot Holes

Introduction

by Werner Burger, Benjamin Künstle, Matthias Stöhr Herrenknecht AG | Schwanau | Germany

Fig. 1: Herrenknechts new Boxhole Boring Machine (BBM)

A large number of vertical or inclined small-diameter slot holes need to be excavated in many underground mines worldwide. To this aim, Herrenknecht has developed and built a new Boxhole Boring Machine (BBM) (Fig. 1). Its concept is based on the well-proven Microtunnelling pipe jacking technology – an area in which Herrenknecht can look back on 25 years of experience in international projects.

Initial results of the BBM indicate that the machine is capable of achieving high and consistent production rates and guarantees high mobility and flexibility compared to other methods.

With this new BBM technology we’re targeting a higher safety standard and requires minimal drift dimension. . Higher production rates can be achieved using the Herrenknecht BBM resulting in significant time savings in producing slot holes compared to conventional drill and blast excavations. The faster and more safely slot holes can be constructed, the earlier the actual production in the mine can start or be continued.

The Boxhole Boring Machine was developed for fast and safe construction of vertical and inclined slot holes (± 30° from vertical) with a diameter of up to 1.5 meters and a length of max. 60 meters in hard rock formations. During development, the design was focused mainly on increased safety due to a remote operated machine, higher productivity and optimum machine mobility. Quick relocation of the BBM and minimum space requirements were also key factors of the design.

Today, the BBM is primarily deployed in gold, copper and other ore mines usually prepared in accordance with the block caving method, whereby the BBM largely contributes toward preparing the draw points (ore extraction points) during the production process. Other applications include drilling ventilation shafts or preparing ore passes for transporting ore between the production level and the haulage level.

For transporting the BBM between different locations in the underground, a compact crawler unit provides fast transport and a high degree of flexibility in confined underground conditions. A modular design allows operation even in tight spatial conditions. The jacking frame with the boring unit, cable drum and power pack can be positioned separately.

The BBM-concept

TRANSFER OF TECHNOLOGY The boring unit is positioned in the jacking frame during the transport. In the production area, the jacking frame is adjusted to its correct position and aligned toward the requisite boring angle. To stabilize the system and transfer the operational thrust and torque loads into the rock, the jacking frame is braced against the floor and the back (Fig. 2). Complex foundations can therefore be dispensed with as well as other preparatory excavation work on the back. The thrust forces are transferred from the jacking frame to the machine cutterhead via steel thrust pipes similar to a conventional horizontal pipe jacking operation. The cutterhead is designed for hard rock geologies of 180MPa and more and fitted with multiple-row carbide cutters. Different cutterhead variants equipped with various cutter tools, e.g. single-disc cutters can also be used as an alternative. A funnel on the boring machine below the cutterhead directs the excavated cuttings through the boring machine and the thrust pipes to the material chute on the jacking frame where they slide by gravity into a skip for transporting. Depending on the mine requirements, adapted solutions for further muck handling are also conceivable here.

Issue 04 | 2012

After each meter of exaction, the operation process will be stopped temporarily and a clamping system holds the pipe string and the boring machine in place in order to install and connect the next thrust pipe. A wheel loader is used for installation. A breakout unit allows the thrust pipes to rotate Âą 10Â° if the pipe string is blocked. This mechanism is integrated in the jacking frame. Once the required boring depth has been reached, the boring unit is retracted. The thrust pipes are removed one by one from the bottom of the pipe string until the boring unit is completely pulled back through the drilled hole and is back in the jacking frame. After that, the BBM can be transported to the next site. The Boxhole Boring Machine is fully remote-controlled. The crawler for relocating the BBM is also remotecontrolled. The operator remains in a safe working area while the machine or crawler is in operation as well as during boring and transport.

Field test in the Black Forest After assembly of the BBM 1100 prototype in early 2011, it was tested under real conditions. The „Clara Mine“, a small mine site in the Black Forest close to the Herrenknecht factory (southern Germany) owned by Sachtleben Bergbau GmbH & Co. KG, presented optimum conditions for a field test. Over a period of four weeks, a number of detailed test slot holes were successfully drilled (Fig. 3). Vertical and inclined test slot holes with a diameter of 1.1 meters and a length of 9 meters were successfully drilled and production rates of 9.0 m within 5 hours could be achieved in challenging rock conditions with a UCS of up to 250MPa (Fig. 4). Instantaneous advance rates of 80-100mm/min were achieved. During the test period, valuable data was collected in order to optimize operational parameters and handling details under real site conditions.

BBM goes Down Under – Application in the Cadia East Underground Project After the successful test phase, the BBM was shipped to its destination – the “Cadia East Underground Mine” in New South Wales, 260 km west of Sydney, Australia. East of the Cadia East Underground Mine, gold and copper is produced in the open-pit mine at Cadia Hill. Extensive soil analyses have established additional ore deposits. Newcrest Mining Limited, a leading developer and operator of gold and copper mines, excavates these ore deposits at Cadia and started to excavate the raw material reserves at Cadia East in 2005. Ore deposits cover an area approx. 2.5km in length, 600 meters wide and up to 1.9km deep. These ore reserves are estimated as harboring approx. 19 million ounces of gold and 3 million tons of copper making Cadia East the largest underground mine in Australia and the deepest block caving underground mine in the world with a life time of around 30 years.

Fig. 4: Vertical and inclined test slot holes with a diameter of 1.1 meters and a length of 9 meters were successfully drilled and production rates of 9.0 m within 5 hours could be achieved in challenging rock conditions with a UCS of up to 250MPa.

Preparations are fully underway for excavating the ore deposits with production scheduled to commence in 2013. The Herrenknecht BBM is currently deployed at the production level for developing the draw points making it a key component in development of the mine. Mancala Pty Ltd., a privately-owned group of companies providing specialized design, engineering, construction and excavation services for the Australian mining and construction industry, ordered a Herrenknecht BBM1100 in October 2010. After transportation and commissioning in Australia in September 2011, the BBM was transported to Cadia East. During the test run and commissioning at a depth of approx. 700 meters, three vertical test operations with a length of approx. 18 meters were successfully bored in fractured and blocky rock formations with a UCS of up to 200MPa (Fig. 5). The BBM1100 has been in operation at a depth of approx. 1000 meters at the Cadia East production level since November 2011 where it plays a major role in constructing draw points for the subsequent production process.

Issue 04 | 2012

To date, more than 40 slot holes (as at June 2012) have been produced with an average length of 16.5m and an average advance rate of 1.5m/h. The operator has succeeded in realizing up to three slot holes a week in single-shift operation (incl. setup, boring and transport preparation) thereby offering the mine operator and contractor security in terms of further planning

Conclusion and outlook The Herrenknecht Boxhole Boring Machine (BBM1100) has been successfully used under real site conditions in the Cadia East Underground Project in Australia. To date more than 40 slot holes have been drilled with a high performance level. The BBM technology offered by Herrenknecht represents an alternative concept for mines, planners and contractors to previous methods of producing slot holes of various diameters and lengths. BBM technology can be individually adapted to the respective mine requirements making it suitable for use in practically any mine.

Sandvik Construction:

Large order for mobile crushers and screens received from Japan Seit Sandvik Japan has recently delivered the first heavy mobile crushers in over 20 years to one of their best and most loyal customers in Japan - the Tochigi based Showa Corporation. Part of the renowned Fujisaco group, the Showa Corporation has been a Sandvik customer for five years, purchasing a variety of Sandvik drill-rigs, breakers and medium range mobile crushers and screens. Now they are also Sandvik s first customer in Japan for the acclaimed U-440 range of tracked crushers.

Large order for mobile crushers and screens Mr. Yamanoi, the owner of the Showa Corporation, is one of the biggest quarry owners in Japan with a total of ten different sites, and employing over 500 people. Although he has been a loyal customer of Sandvik s for the last five years, he has now chosen to work in partnership with Sandvik using the processing power of Sandvik s highly productive U-range of mobile crushers. This range of larger mobile equipment was chosen by Mr. Yamanoi because of its proven high performance, and ability to deliver a consistent high quality end product. As Mr. Yamanoi, and his companies, possess a reputation as being some of the most forward thinking and innovative concerns in Japanese quarrying, the processing power of the Sandvik U-range of tracked crushers have provided the Showa Corporation with the perfect solution for their stringent crushing requirements.

Issue 04 | 2012

Discussions between the Showa Corporation and Sandvik began in late Autumn 2011 when Hiroshi Kezuka, Sandvik Regional Product Line Manager for mobile crushers and screens, together with Peter Delbrant, Sandvik Product Line Manager for the U-range crushers, met with Mr. Yamanoi. As a result of this meeting Mr. Yamanoi placed an initial order for eight mobile crushing and screening units. The order comprised of two sets of equipment each consisting of an UJ440i jaw and US440i cone crusher complete with hanging screens, plus an UH440i cone and QA450 triple deck screener.

A key piece of equipment to the successful operation of each crushing and screening train is the UJ440i jaw crusher. This state of the art machine maximizes production through its class leading feed opening, which coupled with a hydraulic close side setting enables rapid changes through push button operation, further enhanced by integral intelligent operation. The HD crusher utilized on the UJ440i is capable of handling any type of hard rock, in any climate including the most extreme weather conditions when fitted with an optional engine pre-heater. Quick setup time combined with site-to-site transportability, are integral design features that ensure the unit is able to rapidly process materials in any location. Both crusher and unit are manufactured to the highest quality, utilizing Sandvik components, meaning that the number of spare and wear parts that need to be stocked is minimized due to the inherent consistency of manufacture. Trouble free and safe operation is ensured due to automatic and continuous monitoring of the production process, by the in-built intelligence control system. The Sandvik UH440i and US440i tracked cone crushers, making up the other key components of the two production units, are proving to be the perfect choice for the Showa Corporation due to their high flexibility. As fully mobile secondary crushing units they are providing a rapid return on investment

through their high productivity and low operational costs. Like the jaw unit fitted to the UJ440i, the cone on both these crushers is able to handle any type of hard rock material, in virtually any climatic conditions, due to its high quality construction using only the highest quality components. This is providing the Showa Corporation with trouble free and optimal production, which is ensured by on board high level Intelligence, thereby enabling minimal set up time through the unit s sequential start with memorized application data. This precision crusher is further equipped with automatic setting regulation, Sandvik ASRi, and in combination with the unique CLP crushing chamber provides excellent versatility. One of the keys to both Showa s high productivity and efficiency has been the cone unit s automatic setting system, ASRi, which further optimizes cone crusher efficiency, and automatically adapts the crusher to variations in feed conditions. By continuously measuring and compensating for crusher liner wear, ASRi allows for optimal utilization of crusher liners, and schedule liner replacements to coincide with planned maintenance stops. The ASRi also assists in keeping the crusher choke fed in order to maximize rock-onrock crushing, which helps ensure the highest quality end product. The Sandvik U-440 tracked crushers are currently used in two crushing trains to specifically produce aggregate for concrete production. The first production unit concentrates on producing a 20-5mm

www.advanced-mining.com

TRANSFER OF TECHNOLOGY limestone product, whilst the second produces both a 20-5mm and 5-0mm product from a hard sand stone and andesite. Both crushing trains are reportedly operating at high throughput, and producing superb product shape. In addition to this, smaller members of the Sandvik mobile crushing and screening range, in the form of the QJ340 jaw crusher, QA140 screener and QE330 scalper, are used for special size production at various points of the sites, whilst the QJ240 jaw crusher is utilized to crush concrete for recycling and reuse. These latter elements further provide the Showa Corporation with enhanced operational flexibility whenever and wherever it is needed. As aftermarket care is key to Sandvik s operational ethos, and thus ensuring that the Showa Corporation would be able to get the very best from their investment, four people were invited from the Showa Corporation to come to Europe as guests of Peter Delbrant. Initially they undertook service training in England, and then proceeded to the Svedala factory in Sweden, in order to learn more about the Sandvik heavy range of equipment, as well as to see heavy units operating in the field. So as to capitalize on the successful trip to Europe, Peter Delbrant recently ran a further course in Japan. This has undoubtedly paid off as Mr. Yamanoi has recently placed a third order with Sandvik that not only comprises of two additional QA440 screens and a US440i crusher, but also two members of the “super-heavy” range of mobiles – UJ540 jaw and UH640 cone respectively.

Issue 04 | 2012

The order from the Showa Corporation is the first step in introducing the Sandvik U-range of larger, heavy duty mobile crushing and screening equipment to Japan, and seeks to build on the excellent work already undertaken in expanding the market for the Q-range of crushing and screening equipment. All units in the Sandvik U and Q ranges of mobile crushers and screens provide customer-focused solutions for large and small operations within the construction and aggregates industries. Although perfectly capable of operating independently, they are also able to work in conjunction with each other, thereby supplying the Showa Corporation with two fully functional screening and crushing trains.

Sandvik helps Stancills Inc. make a greener Mall The National Mall in Washington D.C. is the world famous location of presidential inaugurations and political rallies, proving to be one of the most popular tourist destinations in the USA. With an estimated 24 million visitors a year walking on the grounds of The Mall, it is now the country s most visited park; a fact that has led the soil to being so heavily trampled and compacted that grass has been hard to grow. The state of disrepair to this national symbol led to long called for renovation of its grounds which was undertaken by Stancills Inc., whose endeavors were aided by a Sandvik QA440 screener.

Sandvik helps Stancills Inc. Stancills Inc. is a family owned and managed engineered soils manufacturing company, located along the northern shores of the Chesapeake Bay in Maryland. It was founded in 1934 by G.L. Stancill, a farmer from North Carolina, who initially ventured into the business of sand and gravel mining. He started with collection of material from gravel banks by making use of only a shovel and a pick-up truck that was funded with savings from his 4 years of service in the Army. Productivity dramatically grew in 1938 when he acquired his first mechanical shovel, and by the time of the out-break of the Second World War G.L. Stancill was able to once again serve his country proudly through providing an essential service to the war effort.

As the sand and gravel mining business successfully grew, three of G.L. Stencills sons became involved in the management and operation of the business. The growth experienced led to the business covering a wider geographical area, but at the same time the supply of construction materials became very competitive; this necessitated a new strategy in order to stay ahead of the competition. At the same time that the supply of construction materials was becoming a congested market place the demand for manufactured soil in the region was

TRANSFER OF TECHNOLOGY booming. This, when combined with environmental legislation requiring the use of specialized soils for storm water mitigation, made the engineered soils business a worthwhile area to diversify into. This vision, combined with the attention to detail of customers current and future needs, allowed the new business model to thrive, and made Stancills Inc. the engineered soil supplier of choice within the region. This prestigious reputation proved essential in winning the contract for screening topsoil at the National Mall. The job of renovating the topsoil of one of the national symbols of the USA is not a minor one: the Mall not only represents a major tourist attraction, but the workmanship will be beholden by the great and the good from all over the world. Thus, the material specification required was very fine < ½ , which needed to be sized out from the grounds, which had by then accumulated a considerable amount of debris and gravel. This onerous task required a highly productive and reliable screening machine; one that could not only produce materials at high throughout, but also possesses exceptional levels of screening accuracy. Thus, in order to undertake this high status work Stancills chose the Sandvik QA440; a screening machine that combines exceptional screening area with the revolutionary patented Doublescreen technology which is unique to Sandvik.

In order to process and refine the soil the work on the National Mall project involved feeding the stockpiled and excavated material directly into the hopper of the screen with a loader. This proved to be an easily accomplished task as the QA440 s hopper is capable of handling up to 14.8 yd3 of feed material, and is flexible enough to be fed from an excavator, crusher or another screener. In order to achieve the < ½ final product size required, the machine was fitted with 2 and 1/2 square meshes, with the top mesh screening out oversize material – this being found in abundance on the project. A major reason for the success of the screening of the material, and the production of usable soil products, was due to the design of the Doublescreen box; this allows for the two screen boxes to be positioned at different angles to one another. In order to rapidly remove the over-size material from the required products, the primary box was positioned at a very steep angle, thereby allowing the secondary screen box to perform as a highly efficient secondary grader. This revolutionary screening technology is unique in the market, and makes the QA440 one of the most efficient and reliable mobile screeners available today, and thus ideal for the National Mall material. In addition to the advanced Doublescreen box the QA440 boasts impressive 20 x 5 screening decks, as well as possessing hydraulic folding conveyors purpose designed for massive stockpiling capabilities,

The tracked and fully mobile QA440 may be easily maneuvered within the site via the use of remote control, enabling total flexibility of use as it is able to maneuver, and then quickly start production in a different location. These features make the QA440 ideal for screening jobs where reliability, flexibility, mobility and high production are paramount; even in spaces with restricted access, such as urban locations. Today Stancills Inc. is run as a partnership between G.L Stancills son Terry, and his daughter Emlyn Stancill. Of their acquisition of the QA440 Emlyn stated: “We chose Sandvik because of the competitive pricing, and the quality of course, but most of all because of the excellent support received from Chris Quinn. His customer service has been essential. More than a salesman, he has felt like a member of our team.” Chris Quinn, Area Manager for Advanced Equipment, distributor of Sandvik mobile crushers and screeners in the Mid-Atlantic States, says of Stancills: “Dealing with Terry and Emlyn has been an absolute pleasure. They were keen in getting the right equipment, and working closely together with them in order to understand their needs has been essential. It gives me great joy to see how we have contributed to make their business prosper.” Stencills work on the grounds of the National Mall in Washington has been a perfect testament to the skills that they have developed over the years. It also shows that the dynamic business thinking that led to the company diversifying into soil engineering is alive and well with the current management, as the adoption of radical screening solutions with the QA440 clearly shows.

Sandvik QJ341 mobile jaw crusher increases Argentinian quarry s production by 100% From initial success in the mid-1990s supplying crushed rock for the construction of new roads, Caminos del Mercosur S.R.L., has recently enhanced its reputation as an innovator in aggregates production and supply through the adoption of tracked crushing technology. Based in Posadas, Misiones, Argentina, the company has modernised its production capabilities through investing in a modern, mobile crusher, the Sandvik QJ341, which has allowed Caminos del Mercosur to increase production by 100%.

Sandvik QJ341 mobile jaw crusher Caminos del Mercosur S.R.L. is a family owned company based in Posadas, Argentina, having been founded in 1996 by Eduardo Bogado. The family, and specifically Eduardo, possess a long and proud association with the quarrying industry, and are able to call upon many years of industry experience in order to supply crushed rock and aggregate for use within the construction industry. This proved to be particularly pertinent, as from its inception the company was quick to take advantage of the opportunities offered by infrastructure projects that were undertaken in Argentina during the mid-90s. Thus, their experience enabled Caminos to become the supplier of crushed rock to the contractor working on the construction of the Route 12 highway.

At the time of the Route 12 highway construction project, the Caminos owned quarry was equipped with stationary crushing and screening equipment, which was able to produce between 3,000 and 5,000 tons per month. As the demand for aggregates grew, Eduardo Bogado invested in more stationary equipment, which resulted in an increased capacity of 20,000 tons per month, thereby ensuring that the company became one of the principal suppliers of crushed rock and aggregates in the area.

TRANSFER OF TECHNOLOGY Fig. 2: Eduardo Bogado explains: “I chose Sandvik because of the good communication and technical advice given before the purchase of the machine. Having this mobile crusher will allow us to increase production by 100% compared to the stationary equipment we owned before, and will position us more competitively for supplying customers located at a great distance from our quarry. It is an investment I feel very proud about.”

Although able to satisfy the demands for aggregates locally, Caminos del Mercosur S.R.L. soon found its market being restricted. This was mainly due to the transportation costs of the crushed rock, which were making the final price of the supplied aggregate too expensive to be competitive. Thus, many prospective clients from further afield were finding it more economical to source crushed rock and aggregate locally, and Caminos client base was consequently limited to construction companies operating in the local area. It was this competitive disadvantage which incentivized Eduardo to reconsider his options, and to adopt a radical solution to his problem: the purchase of a tracked jaw crusher. It was at Conexpo in 1999 that Eduardo first became aware of the possibilities available through the use of track mounted crushers and screeners when he visited the Extec (subsequently acquired by Sandvik in 2007) stand. The tracked crushers and screens seen on the Extec stand were capable of being moved not only within the quarry, but also of being transported on the roads by means of a low loader. Of vital additional importance the machines are able to start operating almost immediately on arrival at site, with no need for time consuming set-up, as is the case of stationary equipment. Eduardo was suitably impressed; so impressed that when his business requirements changed he sought out the machinery he had seen all those years before. However, as

Issue 04 | 2012

the acquisition of mobile equipment was uncharted territory for him, Eduardo asked for advice on what was the most suitable machine for his needs. To this end, and acting on a recommendation, Eduardo invested in a QJ341 mobile jaw crusher from Sandvik - the latest development based on the Extec C12 crusher he had seen in those years previously. The QJ341 is the latest development in a long line of tracked and mobile jaw crushers manufactured by Sandvik Construction. Possessing a jaw opening of 1200 x 750mm (48”x 30”), and a production capacity of up to 400 tons per hour (depending on multiple variables), this state of the art crusher has been designed for ease of operation through utilizing such features as hydraulically adjustable CSS (closed side setting), high reduction ratios-crushing speed-productivity, reverse crushing action to relieve blockages, plus an automatic central lubrication system. In addition to the above qualities which Eduardo found so attractive, the QJ341 encompasses many innovative features to ensure enhanced operator safety as well as continuous, uninterrupted crushing, including a load control system for the feeder drive, level sensor fitted to the jaw, and speed wheel fitted to the main conveyor. The QJ341 is also fitted with a hydraulic raise and lower facility to the main conveyor which enables increased magnet clearance, together with easier transportation.

The Sandvik QJ341 has certainly made a difference to Caminos del Mercosur s business, as the company is now able to competitively tender for, and to win, work outside the immediate locality. As to why the company chose to specifically purchase a Sandvik machine Eduardo Bogado explains: “I chose Sandvik because of the good communication and technical advice given before the purchase of the machine. Having this mobile crusher will allow us to increase production by 100% compared to the stationary equipment we owned before, and will position us more competitively for supplying customers located at a great distance from our quarry. It is an investment I feel very proud about.”

The features now found on the QJ341 ensure that the machine represents the ultimate tracked mobile jaw crushing solution whatever the application. As Caminos del Mercosur has discovered, it is the ideal crusher when crushing rock to be turned into aggregate, but has proved to be equally effective on concrete, re-bar, as well as bricks or asphalt in a demolition / recycling environment. However, the technical excellence of the crusher means little if is not accompanied by the business acumen of someone such as Eduardo Bogado, who identified the opportunities available through the use of such a piece of equipment.

Metso Minerals: Smooth transition

Metso Minerals (Germany) GmbH Bochum | Germany

to new-generation jaw crusher in Germany

öhrig is a German company with a rich heritage. The company has been quarrying granite at its plant in Bergstrasse in the Sonderbach district of Heppenheim for three generations. Röhrig’s superior product variety is one reason why the company’s proximity to its customers can be understood in more than just physical terms. The company’s high level of innovation has allowed it to establish itself as a reliable supplier of materials, both regionally and internationally. This operational and technical expertise always manages to keep in step with growing market requirements.

Smooth transition to new-generation jaw crusher In terms of technical processing equipment, Röhrig has used a Nordberg C160 stationary jaw crusher from Metso since 1992. At the start of 2012, it was finally exchanged for a more up-to-date version from the same model range. Metso’s C Series is specifically designed to pre-crush hard rock and can cope effortlessly with even the hardest of materials.

Issue 04 | 2012

Fig. 1: Norbert Ried (fourth from left) installed the new C160’s predecessor 20 years ago and is delighted at the durability of the powerful crusher that is now making way for a newer model. Also pictured, from left to right: Manager Volker Angermann, Assembly Manager Maik Engelstätter, Technical Manager Stefan Koob, Project Manager Dominic Schönhardt, Managing Director Marco Röhrig, Service Technician Stefan Kolze, and employees of the installation company Stafemo.

www.advanced-mining.com

TRANSFER OF TECHNOLOGY Fig. 2: On the hook: after the old C160 was lifted out by crane, the new crusher was installed in almost no time. Only the roof of the housing had to be removed.

The dimensions of the new stationary jaw crusher are identical to those of the old one, which means that it could simply be slotted into the housing vacated by the previous version. Third-generation Managing Director Marco Röhrig expects the new machine’s service life to be just as long as the previous model due to the product upgrades that have been implemented. The integral motor base is another plus point; in models made by other manufacturers, it is located outside the crusher. This element of good fortune ensured that Röhrig could reuse the housing without any additional rebuilding. Another advantage lies in the revision of the guards for the C160’s drivetrain and flywheel. The sturdier construction method used for the crusher requires fewer parts, which facilitates easier installation and maintenance, and it makes it simpler to access the motor.

Issue 04 | 2012

Under the watchful eye of Metso’s Assembly Manager Maik Engelstätter, the entire project, including removal and installation, was successfully completed within two weeks.

Installation making the most of the available space Röhrig will likely remember the day the new crusher was installed for a long time: The pitman and main frame were delivered separately prior to installation and assembled on site. It took just one hour to replace the old stationary crusher with the new model. A lorry-mounted crane was used to position the 85-ton crusher with millimeter precision in the crushing plant. Once the new crusher had been positioned in the existing steel structure, the next task was to fix it into place as securely as possible, despite

www.advanced-mining.com

TRANSFER OF TECHNOLOGY the limited space. Special vibration dampers were installed at a height of two meters to prevent the crusher from sliding sideways off its mount. An initial test run with materials was carried out around one week later, after all the electrical cables had been installed. Simultaneously with the installation of the C160, which is the first of the latest generation of crushers to be installed in Germany, a new Nordberg GP100 cone crusher was also being installed in Röhrig’s chipping plant. Röhrig is convinced that the technical improvements made to the new Metso crusher can only be an advantage worldwide.

Röhrig places great value on consistent product quality, maximum added value, and optimum refinement of its product range. Bearing in mind that Röhrig has enough reserves of raw material to last for the next 150 years, the company can confidently continue to develop, with an emphasis on quality rather than quantity.

Crisplant sorting technology in use at sportswear manufacturer NIKE:

High efficiency, low energy!

BEUMER Group GmbH & Co. KG Beckum | Germany

he NIKE China Logistics Center (CLC) Taicang, Jiangsu, is the company s largest distribution center in Asia and handles all shipments of NIKE apparel and footwear for mainland China. The 200,000m2 facility has brought a number of unique operational features to the apparel and footwear industry in China for the first time. From the outset the center has helped define how largescale facilities can operate more sustainably, with the main design and specification criteria led by the intent to create a logistics center that brought together a highperformance operation with NIKE s global commitment to sustainability and the environment. With an extensive conveyor network, high-tech Crisplant sortation equipment and technologies such as voice picking, the facility is able to operate more efficiently and accurately than a more traditional distribution center, giving NIKE a huge advantage in handling its products in China. A large part of the energy consumed in a distribution center is used to run the sortation equipment and conveyors, so NIKE was intent on employing the most energy efficient machines available. The company decided on the Crisplant

LS-4000 cross-belt and tilt-tray sorters, which use linear synchronous motor technology to reduce energy consumption by 75 percent compared with sorters using conventional technologies. These sorters, plus Crisplant s state-of-the-art software controls, are helping NIKE achieve a number of its core corporate goals: increased operational efficiency, shipping flexibility and accuracy, as well as reducing handling costs, energy consumption and the environmental impact of its operations.

Sortation process The sortation process starts with cartons being unloaded from trucks in the receiving area and then stacked on pallets. The pallets are then moved into the very narrow aisle (VNA) warehouse area.

Issue 04 | 2012

www.advanced-mining.com

TRANSFER OF TECHNOLOGY Fig. 2: Final sorting: Boxes are fed via chutes to the Crisplant LS-4000CB Cross Belt Sorter

As required, pallet loads of cartons are selected from the VNA racking and transferred onto a conveyor that merges the cartons onto a line sorter. The line sorter delivers the cartons to three possible destinations depending on whether the goods are to be shipped in batches or made up into new cartons containing a number of different items: â&#x20AC;˘ Whole cartons for onward shipment are delivered to the shipping sorter â&#x20AC;˘ Cartons with items ordered in whole-carton batches go to the pre-sorter induction area â&#x20AC;˘ Cartons containing items that will be collated into mixed-item shipments are sent to the storage Items unpacked from the cartons are placed into storage racks from which operators pick and place the individual items into plastic totes. The conveyor transports the totes, containing the individual items, to a conveyor on Level 2 of the building. These totes and whole cartons containing batches of the same item are then merged before being emptied and items are manually placed onto the LS4000CB cross-belt pre-sorter. This automatically sorts the items in the totes into pre-defined hoppers, which are emptied at the hopper tipping area, from where a system of belt conveyors transports them to manual inductions for loading onto the final sorter.

The final sorter is a second Crisplant LS-4000CB crossbelt sorter, which automatically distributes the individual items into chutes that have been specially designed for the NIKE CLC to reduce the footprint of the sorting area. The chutes feature dividers that rise following the delivery of a complete batch, thereby separating it for packing into a single carton by the operator below. The carton is then pushed onto a roller conveyor for delivery to the Crisplant LS-4000E tilt-tray shipping sorter.

Sorters and controls All three Crisplant sorters at the NIKE CSC are from the LS-4000 family, a range that is under constant development. Any improvements that are delivered for the LS-4000 standard product will flow down to the cross-belt and tilttray models as well. The LS-4000 sorter system and machine controls are seamlessly integrated with NIKE s Warehouse Management System. The ability to combine precise control of individual machines, with systemwide visibility of workflows, enables continual optimization of the system and the avoidance of bottlenecks for faster throughput and higher productivity.

TRANSFER OF TECHNOLOGY Fig. 4: A transparent workflow encompassing the entire system ensures precise control of each machine

The future To ensure maximum operational security, NIKE entered into a three-year service agreement with Crisplant under which service engineers are stationed on-site for support and preventive maintenance of all material handling equipment, including management of the on-site spareparts inventory. This arrangement enables the systems to be updated as new sorter technologies and software controls are introduced.

The largest articulated underground mining truck in the world! Preview at Las Vegas

tlas Copco gave attendees a sneak peek at the world’s largest articulated underground mining truck, the Minetruck MT85, at MINExpo in Las Vegas. The Atlas Copco Minetruck MT85, has been designed for demanding conditions with focus on safety, ergonomic and operators comfort to maximize productivity in underground haulage.

Ben Thompson, Product Manager at Atlas Copco’s Underground Rock Excavation Division, explains: “This truck is designed to fit the same drift dimensions of 50 and 60 tonne class trucks with one essential difference. It will haul 85 tonnes which gives a tremendous productivity boost in terms of fewer trucks and tonnes/kilometers per hour.”

Thompson emphasizes that the Minetruck MT85 is also fast and highly maneuverable on ramps and inclines. “This means that fewer cycles need to be made which, in turn, reduces the cost of transport in relation to the amount of material hauled. Not only that,” he adds, “the new MT85 truck now gives mining companies a more cost effective way to haul ore in the mine. It makes it more attractive to go for deeper ore bodies by ramp instead of sinking a shaft.”

emissions have also been reduced to a minimum as the diesel engines are needed for moving the rigs around the site while electricity is used for drilling. Furthermore, stage 3B/Tier4i engines and biodegradable hydraulic oils are offered as options.

Underground Manager

Comments from the Product Manager Johan Jonsson, Product Manager at Atlas Copco’s Underground Rock Excavation division, explains: “The new Boomer combines all the benefits of Boomer technology together with a wide range of new features and functionality to meet any challenge that miners may face.“ “With these improvements, we are confident that the new Boomer series offers one of the most powerful and productive underground mining rigs and tunneling rigs on the market.” Jonsson also adds that the new series satisfies the increasing demand for automation as well as documentation of all drilling operations.

Underground Manager is a new Windows™ based software package designed to be used in conjunction with Atlas Copco‘s range of intelligent underground drilling equipment. The new software incorporates functions that were previously separated into individual products, such as Tunnel Manager for face drilling and Ore Manager for long-hole drilling. Underground Manager also introduces functions and features that were not previously supported, such as blast design and blast simulation. Other features such as Computer-Aided Design (CAD) file import/export will allow users of the software greater flexibility in such areas as drill plan design. It contains a new drill plan generator, complete 3D view of the tunnel, smart interpolation of contours and improved logging and reporting functions. The new Boomer rigs will be available via Atlas Copco’s own worldwide sales organization from 2013 and can of course also be used for tunneling work in civil construction.

Comfortable and environmental Operator comfort, safety and environmental care also get priority. For example, the FOPS/-ROPS certified cabins are air-conditioned and ergonomically designed featuring the latest operator seat and controls. In the drill rig, the operator is in focus. The operator should feel good in order to make a good job with high productivity. The large 3- and 4-boom rigs offer a new improved and more ergonomic chair for the operator. The arm rests have a flat design with just two multi-functional joysticks instead of four. This eases and speeds up the work for the operator. Depending on the rig type, you can choose to operate the rig from a standing position or sitting position. Carbon

supplies first TBM for Metro construction in Rio de Janeiro Herrenknecht AG is supplying a tunnel boring machine with a diameter of 11.46 meters for the construction of the new metro line 4 in Rio de Janeiro. It will contribute to relieving the traffic routes in the metropolitan area. At the company’s headquarters in southern German Schwanau the first tunnel boring machine to be used in Rio de Janeiro was accepted by the customer in late September 2012. During the factory acceptance Regis Velasco Fichtner Pereira, Secretary of State of the state of Rio de Janeiro, presented the project to the Brazilian media representatives in attendance.

TBM for Metro construction in Rio de Janeiro Schwanau, Germany, 2012. The »Cariocas«, the inhabitants of Rio de Janeiro, have some eventful years ahead of them. In 2014, Brazil hosts the soccer World Cup. Two years later, in 2016, the Summer Olympics are in Rio de Janeiro. In between, in 2015, the 450th Birthday of the city will be celebrated The state government of Rio de Janeiro is investing in a range of infrastructure projects to improve the traffic situation for the approximately eleven million inhabitants of the metropolitan area, and for the expected guests. One major project is the construction of the new Metro Line 4, with a total length of 14 kilometers. This summer UNESO put the city of Rio de Janeiro on the World Heritage list. Rio de Janeiro possesses the world‘s largest urban forest. About a quarter of the urban area consists of mountainous landscapes including some steep, unbuildable slopes. The population density in the city is correspondingly high, as is the pressure on the transport infrastructure. It is completely overloaded and urgently needs to have its capacity expanded for the coming big events. In addition to the two existing metro lines with a total length of about 41 kilometers, the new »Linha 4« along the Atlantic coast is being built to create an efficient

From Ipanema, Metro Line 1 travels towards the city center, where the Maracanã stadium is currently being completely modernized for the soccer World Cup and the Olympic Games. Herrenknecht is supplying a tunnel boring machine with an EPB shield (Ø 11.46 meters) for the 4.6 kilometer long section of the new Line 4 between the stations »Gavea« and »General Osorio«. On September 27, in the presence of the representative of the state government of Rio de Janeiro, State Secretary Velasco Regis Fichtner Pereira, the acceptance of the machine by the customer took place at the Herrenknecht plant in Schwanau. The customer is the »Consórcio Linha 4 Sul«, consisting of the Brazilian construction companies Construtora Norberto Odebrecht S.A., Construtora Queiroz Galvao S.A. and Carioca Christiani Nielsen Engenharia S.A. For the second largest city in Brazil, it is a first: for the first time a tunnel boring machine is being used, after all previous tunnels were built conventionally or as cut-and-cover tunnels. To ensure the machine can cope with the different ground conditions along the tunnel route, the Herrenknecht

NEWS & REPORTS engineers designed it so it can be converted in the tunnel. Herrenknecht project manager Carlos Manzano Rey explains: „It is planned that the machine will cover the first 300 meters in open mode, then be converted for about 3,000 meters in closed EPB mode. Finally, around 1,300 meters will again be tunnelled in open mode.“ In open mode, the firm hard rock (gneiss) is transported away on a conveyor belt. In closed EPB mode removal is handled by a screw conveyor whose conveying speed simultaneously safely and precisely regulates the face support pressure during excavation in the predominantly sandy soil. Another special feature of the machine for Rio de Janeiro‘s Metro Line 4 is the articulation in a diameter range of more than eleven meters. It will allow the tunnelling team to cope with the tight bends with a radius of just 250 meters in some cases. The moulds in which the approximately 19,000 concrete segments for the tunnel lining are produced are being supplied by the Group subsidiary Herrenknecht Formwork. In addition, for the operation of the machine Herrenknecht is supplying the navigation system (VMT), the tunnel belt conveyor (H + E) as well as vehicles for the transport of materials and personnel in the tunnel (Technimétal).

DEEP DRILLING WORKS IN KIRCHWEIDACH SUCCESSFULLY COMPLETED USING THE INNOVARIG The deep drilling rig Terra Invader 350 „InnovaRig“ set a new drilling record in the Upper Bavarian town of Kirchweidach. In the second well a drilling depth of 5,133 meters was reached. Herrenknecht Vertical GmbH, a subsidiary of Herrenknecht AG, designed the deep drilling rig especially for the exploration of geothermal energy at great depths. The completion of the deep drilling works paves the way for the construction of a new environmentally-friendly geothermal power plant.

Terra Invader 350 „InnovaRig“ The renowned drilling company H. Anger‘s Söhne relied on the tried and tested Herrenknecht deep drilling rig „InnovaRig“ Terra Invader 350 to carry out two deep drilling operations in Kirchweidach (Bavaria/Germany). Two earlier projects in Bavaria and Lower Saxony convinced experts of the efficiency of the rig. The company GEOenergie Kirchweidach GmbH that has been established specially for this project ordered the rig for the two drilling operations and the tapping of thermal waters at a depth of 4,000 meters. GEOenergie Kirchweidach GmbH is also in charge of the construction of the geothermal power plant that is scheduled to feed the grid in early 2013. The power plant will provide neighboring communities with up to 13,000 megawatt hours of heat per year - coming from regenerative sources. The power plant turbines are driven with hot water from the first borehole using special technology. The condensate is then pumped back into the ground through the second borehole in order to be „reheated“. The completion of two vertical deep drillings is thus needed in order to operate a geothermal power plant efficiently. The first well was completed successfully and safely at the end of April 2011. With a drilling length of 4,937 meters the deep drilling rig, with a hook load of 410 tonnes, set a new record. A test then revealed that the well would have a sufficient volume to operate the geothermal power plant; which set the bar very high for the works on the second well, since the tapping volumes have to be almost equal in order to reach the planned power and heating capacity.

The deep drilling rig Terra Invader 350 „InnovaRig“ set a new drilling record in the Upper Bavarian town of Kirchweidach. In the second well a drilling depth of 5,133 meters was reached.

The second deep drilling operation was then also carried out down with a length of almost 5,000 meters. In a vertical depth of 3,800 meters the „InnovaRig“ reached its target level. However, a lifting test revealed that this geological formation would not provide sufficient water for the operation of the plant. To reach the excellent performance values of the first well and to optimize the results of the second well, the drilling crew used the Herrenknecht rig in order to drill a 5,133 meter long sidetrack until the end of November. In December 2011, the following lifting test provided the desired result. A new record was set in the second well with a drilling length of 5,133 meters. Meanwhile, the Terra Invader 350 is already being used on another geothermal project. In Traunreut, a town located about 15 kilometers south of Kirchweidach, the rig has been tapping geothermal resources since MidJanuary 2012 for H. Anger‘s Söhne relying again on safe and efficient Herrenknecht Vertical technology.

ContiTech‘s Electronic Monitoring System Enhances Conveyor Belt Safety Conti®Protect Belt Rip Detection detects longitudinal slitting early on and prevents extensive damage • Reduces repair costs and accident risks Hanover, November 2012. Longitudinal slitting in conveyor belts can be costly. Sharp objects are always ending up on the conveyor belt together with the materials conveyed, especially in the mining industry, in wood processing, or in recycling plants. „If they fall in an unfortunate position during belt loading, they may get caught up and split the moving conveyor belt longitudinally. In the worst case scenario, the belt can be written off completely,“ asserts Dr. Andreas Jungk, application engineer at the ContiTech Conveyor Belt Group. More protection against failures and expensive repairs is provided by the new electronic monitoring system Conti®Protect Belt Rip Detection, which has only been on the market for a short time now. It detects longitudinal slitting early on, minimizes damage, and thus cuts cost and reduces the accident risk. This makes it possible for the conveyor belts to be used even longer. Conti®Protect Belt Rip Detection can therefore contribute to reducing operating costs and protecting the environment.

Issue 04 | 2012

Automatic stop protects conveyor belt Monitoring takes place via conductor loops, which are vulcanized into the conveyor belt. These loops transmit a high-frequency signal between a transmitter and receiver. If a loop is damaged, the signal will break down on the receiver end. The system control then stops the conveyor belt automatically. How long the system needs to come to an emergency stop is determined by the distance between the conductor loops, which can vary between 20 and 50 meters. During an initial learning cycle, these distances are recognized and saved by the system.

The transmitter unit and revolution counter relay the measured data to a central unit, allowing belt damage to be detected early on. (Photo: ContiTech)

NEWS & REPORTS The new monitoring system is also extremely easy to use. „All the signal sequences can be called up electronically so that, if necessary, one can conclude from them about the quality of the loops. An Ethernet connection means that the system can be controlled via a PC and also via the Internet,” explains Dr. Andreas Jungk. Many of the systems allow ContiTech specialists to connect to the system on request to carry out remote maintenance. All of the components used in the Conti®Protect Belt Rip Detection system are extremely robust, which enables them to meet the high demands of the mining and bulk material industries.

New Adhesive Revolutionizes Cold Bonding in Conveyor Technology ContiTech launches innovative adhesive • Increased reliability and safety thanks to new one-component technology! Northeim, October, 2012. Increased reliability and safety despite simplified application is promised by the new adhesive Conti Secur® PREMIUM, which is used for a variety of different cold bondings on conveyor belts. As it only has a single component instead of the usual two, it is ready for immediate use and guarantees a long service life. „In heavy industry applications, we normally use two-component adhesives. Conti Secur® PREMIUM is an innovative new product that requires just one component,“ explains Wolfgang Kerwel, application engineer at the ContiTech Conveyor Belt Group in Northeim. He was the one who originally had the idea for the single-component adhesive, and has worked together with adhesive specialist H.B. Fuller Company to develop a marketable product that is now manufactured exclusively for ContiTech. Conti Secur® PREMIUM has been available since October 15 in 0.8-l containers. It can be used universally in the same way as Conti Secur® BFA. For users, the one-component adhesive based on polychloroprene offers two main advantages – firstly in terms of metering, secondly in terms of application and handling. As there is no need for a reinforcement solution, there is no risk of mistakes being made during metering. Furthermore, every last drop of Conti Secur® PREMIUM can be used, without the adhesive vulcanizing in the container within a short space of time, which makes the adhesive particularly cost-effective. Conti Secur® PREMIUM can be used in a range of different applications, including rubber-to-rubber bonds and rubber-to-metal bondings, as well as for cold splicing of fabric ply belts. Another advantage over two-component adhesives is the reduced packaging volume thanks to the omission of reinforcement solution. This reduces costs both during dispatch and in storage, not to mention during waste disposal.

Keestrack: The early years of quarry Bertrand Ch (Photo: Keestrack)

The quarry in Bra sur Lienne is known for its specific blue and brown slate. This is used in construction of walls, roofs, terraces, floors and dry walls (without mortar). The slate is also used for monuments, graves etc. Mining the quarry is already 50 years in progress and this was mainly done manually. The quarry operates in a niche market where colour, size and shape of the stones are selected on demand of the actual order. Bertrand delivers mainly direct to end users and local contractors. Nowadays the manual selection has been brought back to a minimum. Only a manual selection is done on colour and on specific shape of the stones. Another advantage is that the fines and middle fractions are very specific now, resulting in higher proceeds up to 15 times more.

Keestrack: 2 day test of the Combo in the quarry (Photo: Keestrack)

Also production has doubled leading to a shorter delivery time. Besides these economic solutions the Combo also provides a less labour intensive and much cleaner work environment. Quarry Bertrand has expanded their product portfolio because of the 3 different fractions in the new working process. The 0-50 mm fraction is used for paving forest tracks and roads and gardening decorations. The 50-120 mm fraction for drainage stone or as decorative stone.

The choice for the Combo, the smallest screen of the Keestrack range, was an easy one after a testing period of 2 days. Because manual sorting is still to be done at the oversize conveyor it is essential to have picking stations on both sides. Also the speed of the hopper and the main conveyor is easy to adjust from the picking stations. The easily interchangeable screens of the Combo are also an advantage. A capacity of 250 (metric)Tons an hour is more than enough in this application. Of course the possibility of doing a real test played an important role, because seeing is believing! This story clearly shows that even in niche markets, with small production needs there are enough advantages using a Keestrack screen. Keestrack can offer a solution to you as well.

The impossible proven possible, day after day

Keestrack

KEESTRACK:

he general opinion is that it is almost impossible to screen wood into several fractions with a flat screen surface. At the company Filbois in Seraing, Belgium they prove otherwise day after day.

The site of Filbois is 47.000 mÂ˛ and offers social employment to approximately 15 people. It is one of the missions of the company to offer social employment. The other missions are: recycling wood (for the chipboard industry and as an energy source) and remediating ground on their own site.

Keestrack: Raw material (Photo: Keestrack)

On the site of Filbois they recycle scrap wood coming mainly from waste collection centers. After unloading, the wood is sorted by quality. Using a rough, slowly rotating shredder the scrap wood is reduced to pieces of maximum 300 mm. In the following picking station all contaminations, like plastic, metal, etc. are manually removed. The following hammer mill reduces the scrap wood to a size of maximum 120 mm. Recently the production of chipped wood is separated in 3 fractions using a Keestrack Novum, with extended main conveyor, resulting in a higher profit because of more specific end products. The general opinion is that it is almost impossible to sort wood in several fractions using a flat screen surface but with the right expertise, the right choice of screens, amplitude of the screen box and the right speed this is surely possible. This is proven every day at Filbois!

Keestrack: Keestrack Novum with extended main conveyor (Photo: Keestrack)

The hopper of the screening machine functions as a buffer and makes sure the screen is evenly fed. After fine screening into 3 fractions the middle fraction is used in the chip board industry, the oversize fraction will be reprocessed or be offered for energetic revaluation. The fines fraction serves as raw material for energetic revaluation. The approximately throughput of the Novum is 100 mÂł/ hour.

New enviromental legislation in the Recycling Industry has forced a lot of customers to re-think how they run their business and fortunately Keestrack has helped these customers stay one step ahead. Today we are proud to say that Keestrack was at the forefront of Screening & Crushing and led the way to today`s industry standard with our revolutionary direct fed screens and state of the art impact crushers. In 1994 the company was transformed into a shareholder company. This was a giant leap for product development and production. This first direct fed mobile screening plant was specially designed for the recycling and quarry industry to screen material like stones, rubble, topsoil, clay, recycled concrete, sand, gravel and many other applications. The first Track Screener Keestrack produced was called the Frontier/4518 and was designed specially for the recycling and quarry industry to screen stones, rubble, topsoil, clay, as well as quarry rock. This machine is being manufactured, assembled and tested with the utmost care, and designed in full accordance with EC standards.

The 777 was first introduced by Caterpillar in 1977 and has proven to be a workhorse for mining and large earthmoving customers. The 777G replaces the 777F and delivers greater levels of production and fuel efficiency as well as enhanced safety, operator comfort and service convenience. The 777G achieves greater production with seven percent more torque powering work and new transmission controls that produce quick haul cycles with automotive quality shifting. The production increases are balanced with new fuel saving strategies that include configurable economy settings as well as an adaptive economy mode that automatically optimizes fuel consumption based on the users production baseline. Fuel savings also are realized behind the scenes through features such as auto neutral idle and APECS transmission controls where the truck becomes more fuel efficient at idle in a forward gear and when climbing grades. Customers can choose to engage features like Engine Idle Shutdown and speed limiting to further improve fuel savings.

Issue 04 | 2012

In addition to its fuel efficiency, the 777G is quieter and produces fewer emissions. Caterpillar is introducing its U.S. EPA Tier 4 Final solution on the 777G two years in advance of the effective date of the regulation, which provides customers an opportunity to advance their sustainability goals. The solution is both simple and robust and includes engine technology combined with diesel oxidation catalysts. It requires the use of ultra low sulfur diesel fuel and low ash engine oil, but requires no additional maintenance or operator input. For operations outside of areas regulated by the U.S. EPA, the 777G reduces emissions with Tier 2 or EU Stage II equivalent technology and fuel efficiency. Caterpillar has enhanced braking and traction control for G Series. Hydraulic oil-immersed disc brakes are now standard on all four corners of the truck. The system design increases slope holding capability and provides fade resistant, responsive braking performance.

NEWS & REPORTS system actuates the front brakes as well as the rear for solidly holding the truck on a slope. In addition to brake performance updates, the traction control system on the 777G is now able to differentiate between tire spin and high speed turns so it now can activate at lower speeds. The system now uses the hydraulically applied service brakes for improved response time and modulation from one wheel group to the other. The 777G also features new designs to enhance the safety and comfort of operators and maintenance personnel. The access system is wider, low effort and convenient with new hand rails promoting three points of contact. Inside the cab, the operator experiences 50 percent less sound compared to the previous model. The Cat Comfort Seat is Series III with vibration reducing technology and a three point restraint system. It is highly adjustable and promotes all-day comfort as does a new foot rest and automatic temperature control. The left side window is electric, and like the windshield, features laminated glass for safety. Emergency egress is available through the hinged window on the right side. Object Detection comes standard on the 777G. Using a combination of radars, an in-cab display and multiple cameras, Object Detection provides equipment operators with enhanced awareness for increased site safety. The 777G also offers tire monitoring through use of payload values from the Truck Production Monitoring System and data such as air temperature and truck speed to calculate

the load placed on tires. As tires approach their rated load-speed rating, a warning is given and customers can choose a course of action, including slowing down or reducing payload. Maintenance is quick and convenient with ground level service centers for both electrical connections (located on the front bumper) and fluid fill. The optional fluid fill center provides access to all fluids from one centralized location. It includes a lighted keypad with level indicators giving operators instant information on what needs filling. Additional fluid level monitoring is available to the operator in the cab. Caterpillar is extending its hydraulic oil filter service intervals to 1,000 hours, reducing customer life cycle costs.

Next generation Cat transmission controls The 777G introduces the next generation of transmission control strategies from Caterpillar. Advanced Productivity Electronic Control Strategy or APECS provides greater productivity at better fuel rates with torque shift management that allows the truck to carry more momentum up grades. Drive train durability profits from next generation electronic clutch pressure control, and APECS further provides outstanding shift quality for a smooth ride.

The 777 was first introduced by Caterpillar in 1977 and has proven to be a workhorse for mining and large earthmoving customers.

NEWS & REPORTS Tier 4 Final emission controls transparent to operator New emission control strategies enable the Cat C32 engine to meet Tier 4 Final emissions regulations in the USA and Canada. The strategy includes the Cat NOx Reduction System and two Diesel Oxidation Catalyst canisters, one for each bank of cylinders in the “V” configured C32. Working in combination with ACERT™, the Cat NOx-Reduction

System diverts a small volume of cooled engine exhaust back to the combustion chamber. The result is reduced cylinder temperatures and reduced NOx formation. This NOx reduction system takes full advantage of the cleaner, less corrosive properties of ultra low sulfur diesel fuel and low ash engine oils to maintain service intervals and component life. The two Diesel Oxidation Catalyst canisters trap residual hydrocarbons in the exhaust. This 777G Tier 4 Final strategy is transparent to the operator and does not require additional service for the machine.

Design refinements fit Cat® 993K for worldwide service and enhance performance, fuel efficiency, serviceability and operator convenience.

ecent design refinements for the 993K wheel loader are aimed at better serving mining and quarry customers worldwide by further enhancing the 993Ks ability to deliver reliable, low-cost production with durability and safety. Now available with either a Tier 4 Final or Tier 2 Equivalent Cat® C32 engine, the 993K incorporates new engine control and power train features that boost performance and reduce fuel consumption, while the new Cycle Timer feature adds efficiency to loading operations. The now standard Deluxe Service Center greatly simplifies routine service, and operator convenience and safety features include new controls and an available powered access system.

The updated 993K fuel consumption is reduced as much as 10 percent, achieved by lowering rated speed and equipping the machine with Auto Idle Kickdown (reduces throttle-lock speed after a set idling interval) and Engine Idle Shutdown (shuts down the engine after extended periods of idling). A new battery management system shuts down electrical power after the latter system activates. Complementing these features is the Delayed Engine Shutdown system, which allows the engine to idle after key-off to cool the turbocharger for extended life.

enables on-the-go weighing and payload recordkeeping— now includes a Cycle Timer feature that tracks and stores all aspects of the truck loading cycle in an eight-segment format. Cycle Timer promotes efficient operation by providing detailed information (such as average cycle time, wait time, fuel consumed, and tons produced per unit of fuel) that can be used in management reports.

Service features, operator environment

A new torque converter is matched to work precisely with the reduced engine speed, maintaining rimpull and hydraulic performance, while gaining further fuel savings. In addition, the Powertrain Torque Strategy system ensures optimum converter output at reduced speeds. The system also reduces engine speed for directional shifts made at high ground speeds.

The 993K Deluxe Service Center uses touch-pad switches and indicator lights to allow checking all fluid levels, as well as allowing the draining and filling of fluid compartments from ground level.

Caterpillar Ships 500th D7E TrackType Tractor with Electric Drive

More than 1.4 million gallons of diesel fuel saved to date Caterpillar has shipped the 500th D7E Track-Type Tractor from the company’s East Peoria, Illinois facility The Cat D7E features a first-of-its-kind electric drive system that boosts productivity and efficiency while lowering operating costs and dramatically reducing fuel consumption. D7E dozers are hard at work in a wide range of applications throughout North America, Europe and Australia. K&E Excavating of Salem, Oregon purchased a D7E earlier this year to replace a D7R. “We like to operate with the latest technology, and the D7E fits right in,” said Kerry Kuenzi, president of K&E. In their applications, Kuenzi says they have found the D7E to be quicker and more powerful than their D7R, and in their own carefully measured sideby-side comparisons, “…the new D7E burns half the fuel of our D7R.”

Issue 04 | 2012

A key advantage of the D7E has proven to be reduced fuel consumption. Pre-production studies suggested that the D7E would provide 10 to 30 percent better fuel economy over the previous D7 model, depending on the application. According to Cat Product Link™ data, customers using the D7E have already saved more than 1.4 million gallons (5.3 million liters) of diesel fuel as compared to the previous D7R model. “With diesel over $3.50 a gallon in the U.S. and even higher in Europe, that’s several million dollars going directly to our customers’ bottom lines,” said Scott Johnson, worldwide tractor product manager. “This financial benefit, as well as the corresponding reduction in emissions, will compound as field population continues to grow.” Family-owned Mectec Pty Ltd purchased the first D7E, which meets U.S. EPA Tier 4 Interim/EU Stage IIIB emission standards, shipped to Australia in June. The company works primarily in renewable forests for the Department of Sustainability and Environment and the

NEWS & REPORTS VicForests Silvicultural program. Co-owner Luke Mekkens has found outstanding fuel efficiency and the power and maneuverability he needs for the difficult terrain. His calculations show fuel use of the D7E to be 4 to 7 liters (1 to 2 gallons) per hour less than a Cat D6T he uses to do similar work. “The fuel savings, the power and the versatility give me an edge that puts my business in a really great position for the future,” Mekkens said. Great Lakes Dock & Dredge Company’s fleet has grown to include 13 of the electric drive dozers, and fuel savings was a big part of the purchase decision. “The D7E was a good fit for our company because of the potential fuel savings versus another machine, and the added power that the D7E has over the D7R also was a big plus for us,” said Chris Coolahan, heavy & shoreside equipment manager for the company. Great Lakes has been using the machines to do beach reclamation work all around the U.S. Coolahan also cites Tier 4 Interim certified engines and dealer service capability as contributing factors to the size of their D7E fleet. “We know we can rely on the Cat dealer network for shop and field service, as well as parts availability.”

“Customer satisfaction with this machine has been outstanding,” Johnson said. “Whether the machines are working in construction, oil and gas or landfill applications, the reliability has been fantastic and the reduction in fuel use has been in line with, and often even better than, initially expected. As a result of the tractor’s performance, we’re seeing an increasing number of repeat purchases.”

The Cat CM235 Continuous Miner

First full fleet of Cat® branded underground coal mining equipment goes to work at Armstrong Coal in Kentucky The first full fleet of Cat® branded room-and-pillar coal mining equipment is being installed by Armstrong Coal in conjunction with the opening of its new underground mine at Lewis Creek in Kentucky. The mining company, a subsidiary of Armstrong Energy, purchased 24 machines from Cat dealer Whayne Supply following the dealership s acquisition of the former Bucyrus distribution and product support business. “We re all looking forward to being the first underground coal mine in the world with all Cat equipment,” said Rick Craig, Armstrong Coal s vice president for operations. “We also look forward to continuing our relationship with Caterpillar and solidifying that commitment.” The fleet, which features four Cat CM235 Continuous Miners supported with face haulers, roof bolters, scoops and feeder breakers, began operating at Lewis Creek in late September. It will be supported by Whayne Supply locations in the area. “Caterpillar has a reputation for being a leader in the industry; so when they went underground, we thought it would be a good thing to be part of,” said Rickie Philips, Lewis Creek mine s underground mine superintendent. “We know that Caterpillar will back us all the way. They have a stake in this as much as we do.”

Issue 04 | 2012

Lewis Creek mines the 50-inch-thick (1.27-meter-thick) West Kentucky No. 9 Seam. Targeted sales of clean coal from the mine are 800,000 to 900,000 tons (726,000 to 816,000 tonnes) annually.

Cat equipment above and below ground supported by Whayne While this is Armstrong s first purchase of Cat underground equipment, the company is a long-time Whayne partner. Lewis Creek is also home to a surface coal mine that uses Cat equipment, including rigid-frame mining trucks and articulated trucks. Armstrong has multiple surface mines throughout the region, all of which use Cat equipment supported by Whayne Supply. According to Monty Boyd, Whayne Supply president and CEO, that relationship is what gave Armstrong the confidence to make this decision. “We sold 80 pieces of surface mining equipment to Armstrong as they started their business in Western Kentucky,” said Boyd. “That s quite a trusting venture, and I believe they re putting that same type of trust in us by taking the first full fleet of Cat underground equipment.”

NEWS & REPORTS In addition to being one of its first underground equipment customers, Armstrong outsourced the maintenance of its Cat equipment through a formal Maintenance and Repair Contract (MARC) with Whayne. In preparation for the addition of the full line of Cat underground products, Whayne and their sister dealership, Walker Machinery, both owned by Boyd, are forming a new sales and support division called Whayne-Walker Underground. The new division officially started operating November 1 and will be staffed by Whayne employees and former Caterpillar and Bucyrus sales and support staff well versed in the new products. “Our objective is to provide the new underground mining customers the same, or even better, support and service that they have received in the past,” said Breese Watson, a marketing manager with Whayne-Walker. WhayneWalker Underground will operate out of existing Whayne and Walker facilities throughout the dealers territory.

According to Phil Kelliher, general manager of the North American region for Caterpillar Global Mining, this sale is an important milestone in the integration of the former Bucyrus underground coal mining products. “The trust and confidence Armstrong has placed in us by buying this line of products is absolutely critical,” said Kelliher. “This is the example that we want to build on with our customers.” The new equipment is being put into service as it arrives, with the final delivery expected to take place in early 2013.

The primary goal of the regional politics in line with the common task is that economically underdeveloped regions, through compensation of their locational disadvantage, can keep up with the general economic development and regional differences in development will be reduced. In order to gain insight locally, the delegates foster the direct dialog with the companies in areas with a locational disadvantage. On October 29th, 2012, a delegation of the subcommittee for regional economic politics lead by the Chairman Stephan Mayer (Member of the German Bundestag, CDU/ CSU) visited FRITSCH Milling and Sizing in Idar-Oberstein. Additional members and visitors were: Doris Barnett and Andrea Wicklein (both Members of the German Bundestag, SPD), Manfred Todtenhausen (Member of the German Bundestag, FDP), Dr. Tobias Lindner (Member of the German Bundestag BÜNDNIS 90/DIE GRÜNEN), Wolfgang L. Müller (Consultant SPD parliamentary group), Florian Hartmann (research assistant) and Stefan Hötte (Government Director in in the committee office). In Rhineland-Palatinate visited the delegates besides IdarOberstein, also Kaiserslautern and Birkenfeld. Goal of the visit was in discussions with representatives of the local economy, the Chamber of Commerce and Trade, Chamber of Crafts, state and local politicians to gain a personal insight of the status quo of the structural policy. As part of the tour, the delegates visited several firms which in the previous years profited from the funds from the common task “improvement of regional and economic structures”.

Powerscreen® XH320SR Impresses Logan Aggregate Recycling Inc.

Powerscreen XH320SR impact crusher

The Powerscreen® XH320SR impact crusher is helping Logan Aggregate Recycling Inc The Powerscreen® XH320SR impact crusher is helping Logan Aggregate Recycling Inc. to meet increased demand in a compact, fuel efficient package. Founded by husbandand-wife team Joe and Michelle Logan in the spring of 2010, the company began as a service. “The popularity of recycled aggregates is growing, but local suppliers of these aggregates previously had to rely on contract crushing companies from as far away as Pennsylvania and Ohio,” Joe Logan said. “I have always been a firm believer in doing business in person, with our customers and employees alike. We have tried to focus our service area within a two to three hour radius from Richmond in order to always have a management presence on our projects.” Logan noted that he grew up in the industry working at a construction equipment dealership that his grandfather started. Working in all areas of the company gave him valuable experience with operating equipment in addition to the opportunity to build extensive relationships within the industry. Logan recently purchased a Powerscreen XH320SR impact crusher from Jeff Ford, regional manager of Northern and Central Virginia at Powerscreen Mid Atlantic Inc.

Issue 04 | 2012

“The XH320SR is a great machine,” Ford said. “It is an upgraded version of the Powerscreen 4242SR. A couple of the upgrades include a larger crushing chamber and the Scania engine. The closed circuit machine gives the customer the advantage to transport the machine all in one move to small and tight job sites. The XH320SR is a high-performance machine and is rated at 320 tph.” According to Logan, his company’s purchase of the machine was in order to offer customers a solution for processing materials at plant locations where space is limited. “More and more, we are seeing that asphalt and concrete producers are using every inch of available space in their plants,” he explained. “The 320SR is a closed circuit machine, meaning that the crusher, screen and re-circulating conveyor are all mounted on one trackmounted chassis. The finished product is then conveyed to a stockpile by a track-mounted stacking conveyor. This significantly reduces the footprint of our operation and allows customers to use their real estate for stockpiling material and loading trucks. Additionally, we can move the set-up around the site very quickly and easily.” The machine has been in service for Logan Aggregate Recycling since mid-February and has already logged approximately 1,000 hours. “We have been very impressed with the fuel economy of the Tier IV-interim compliant Scania engine,” Logan

NEWS & REPORTS said. “We also try to practice good housekeeping, and we can walk the 320SR out of the way, clean and grade the working area, and be set up again and ready to run in a matter of minutes.” Although Logan has rented equipment from Powerscreen Mid-Atlantic in the past, this machine was their first purchase from the company. “I met Joe Logan while he was using a competitor’s machine,” Ford said. “When he decided that he was going to purchase another crusher, I took him to see the XH320. Joe immediately saw value in the crusher. The Powerscreen crusher was more expensive, but Joe recognized the quality and realized that we could offer him a higher level of support than any other dealer in Virginia.” Logan has not been disappointed. “We have been extremely pleased with their support,” he said. “Parts and wear items have been in stock, or shipped the next day. Their service technicians also are extremely knowledgeable and professional.” Powerscreen Mid Atlantic is the Powerscreen dealer for the Virginias and the Carolinas. The company’s main office is based in Kernersville, N.C. The Virginia regional office is in Ashland, Va., and includes a sales office and parts and service support.

First Volvo EC250D excavator sold in Great Britain

xtraction, mobile crushing and screening specialist Jim Jamieson of Ellon Aberdeenshire has taken delivery of the first Volvo EC250D excavator to be sold in Great Britain which has gone to work at the company’s Ardelethen quarry.

Volvo EC250D excavator The new machine replaces and EC240C which was originally purchased in 2008 and joins a mixed fleet in the Jamieson arsenal which includes eight Volvo branded machines and an FMX road tipper. “The build quality of the Volvo is ideal for the typical applications we undertake and we’ve enjoyed good reliability and when it’s needed, good support from Volvo’s Stirling support centre,” says Jim Jamieson. At the heart of the EC250D a 6 litre Stage IIIB engine developing 202 nett hp operates in conjunction with an advanced mode control system ensuring the maximum possible hydraulic horsepower available is delivered at a constant engine speed under varying load conditions. Maximum reach with the intermediate dipper arm is a generous 10.7 metres whilst maximum digging depth is 7.34 metres and lifting capacity across carriage at full reach is and impressive 3.16 tonnes. Operators can select the best work mode for the task at hand, ensuring optimum performance and fuel efficiency. Modes include: I-idle, F-fine, G-general, H-heavy or P-power, with the machine automatically setting the appropriate engine speed for the work mode and ECO mode is a new feature that works in G to H (or P) mode. Pump flow is controlled for combined digging and swinging operations to reduce the flow loss through the overload relief valves, while maintaining digging power and maximum swing torque. Eco mode provides better fuel efficiency without loss of performance in most operating conditions as already experienced by Brian Ward. The new ‘smart’ hydraulics system is designed for high productivity, high digging capacity, easy maneuverability and class leading fuel economy. It features improvements that increase total flow and allow cycle times to improve by up to 2.5%. Independent and simultaneous movements of the digging equipment are controlled by an ‘automatic

sensing work mode’. It can also prioritize flow according to the work being done – e.g. to the boom for faster raising when loading or in deep excavations; to the arm during leveling or swing during large slewing angles. An Attachment Management system can store up to 18 presets and enables hydraulic flow to be adjusted as per the requirements of the attachment in use. Covering the whole of Scotland Jim Jamieson specialises in quarrying, contract crushing and screening and general contracting. The family run business is head-quatered at Ellon, Aberdeenshire. Sister company James Jamieson Construction has also recently taken delivery of two Volvo A25F articulated haulers. Volvo Construction Equipment Division markets wheeled loaders, articulated haulers, hydraulic excavators, graders, Volvo Utility Equipment and Volvo road machinery products in the U.K. There are eight strategically placed customer support centres and a network of utility equipment dealers to ensure high quality customer support is maintained throughout Great Britain.

Volvo EC300D excavator scoop Black Gold for Banks Mining

anks Mining, a division of the Banks Group Ltd, Meadowfield, County Durham has continued an association with Volvo Construction Equipment with the delivery of five A40F articulated haulers, two EC220D’s on backacter and two EC300D excavators rigged with bespoke front shovel coaling equipment.

Volvo EC300D excavator This latest assortment of machines has initially been delivered to Banks Mining’s Shotton Surface Mine near Cramlington, the largest approved surface coal mine currently operating in the UK, and is part of an up-grade to Banks’ existing fleet. They join two existing A40E models delivered to the site back in 2009 equipped with coal handling bodies. The new A40F’s have been supplied in standard configuration and are being deployed to haul overburden from the more difficult areas on site where access and manoeuvrability are harder for the larger rigid haulers. The trucks feature 24m³ bodies with a 39000kg load capacity and the Volvo designed and proven drivetrain is powered by a Stage IIIB Volvo D16 low emission engine with a gross power rating of 350kW.

With the EC220D’s working to clean off the last layers of overburden to expose the coal, which can lie in seams from just four inches to over four feet thick, the EC300D’s are used to load coal into high bodied coal haulers. The machines have been converted to face shovel by Messrs Kocurek of Ipswich and feature a bespoke 5m long boom, 3.4 metre face shovel arm and 1.8m³ clamshell bucket. In this configuration the EC300D features a generous forward reach of 9.25 metres and a load over height of 5.75 metres. Heavy duty guards have been fitted to the cab windows and the clamshell bucket is operated via the X1 two way proportional valve.

Whilst Banks Mining has had a long association with Volvo articulated haulers, choosing models from Volvo’s excavator range was a new departure for the company. “Naturally we scrutinised the market place to evaluate what was available but based on the overall package on offer from Volvo and the high availability and reliability of the haulers decided to put their excavators to the test,” said the Banks Group’s procurement manager, Andrew Bennett. Two new twenty-two tonne EC220D’s have been supplied in standard backacter configuration along with two new thirty tonne EC300D excavators fitted with bespoke front shovel coaling equipment.

New Volvo L150G loading shovel on the blocks at Marshalls

arshalls, the producers of premium natural stone has taken delivery of a new Volvo L150G for handling stone blocks at its Cromwell Works in Halifax.

New Volvo L150G loading shovel A new Volvo L150G has been supplied to Marshalls Natural Stone Division which takes over as the works prime mover handling stone blocks weighing up to as much as 18 tonnes. To accomplish the task of receiving yorkstone blocks, primarily from Marshall’s nearby Scoutmoor Quarry, sorting, stacking and feeding the cutting shop, the L150G has been supplied complete with a hydraulic quick fit; a set of bespoke heavy duty block handling forks, an additional set of conventional pallet forks and a 4.2m³ rehandling bucket. In order to cope with the typical weights and size of the blocks an additional counterweight has been added and the machine runs on Michelin L5 XLDD2A tyres. Replacing a telehandler the new L150G has settled in well to the three shifts, 24 hour - five day working week. “Although we operate Volvo shovels at other locations, this is the first time we’ve had one here at Cromwell,” says Production Manager Nigel Buchan. “So far the machine is doing everything that’s asked of it and our operators are pleased with the level of comfort in the cab and the performance of the machine.”

Issue 04 | 2012

The L150G wheeled loader weighing in at twenty five tonnes is firmly in charge of the block handling activities at the Cromwell site which processes on average 800 to 1000 tonnes of stone per week. Featuring a 13 litre Stage IIIB compliant 300hp engine, optishift transmission and axles all designed and manufactured by Volvo, the L150G has a 20% increase in lifting force and 10% increase in breakout force over its predecessor. This coupled to the engine output with high torque at low engine rpm has resulted in faster cycle times and increased productivity. Two stronger, variable displacement load-bearing axial piston pumps and hoses have been introduced to handle the increased pressures. These provide superior control of the load and attachments, as well as high breakout force, faster lifting and tilt functions. A new hydraulic cooling system has been designed to reduce the working temperatures by up to 20oC over the F series model. Fuel savings are further enhanced by the Volvo Eco pedal encouraging the operator to run the machine at its optimum rpm in the engine’s torque curve.

NEWS & REPORTS Another important factor in Marshall’s decision to purchase the L150G was an assured peace of mind since the machine has been delivered with a full five year repair and maintenance package (Volvo’s Gold service agreement package). “Knowing your monthly fixed costs in this 24 hour, 5 days per week application is a real benefit when it comes to forecasting and budgeting,” continued Mr Buchan. Established in the late 1880s, Marshalls is the UK‘s leading manufacturer of superior natural stone and innovative concrete hard landscaping products, supplying the construction, home improvement and landscape markets. The Group operates its own quarries and manufacturing sites throughout the UK, including a network of regional service centres and 2 national manufacturing and distribution sites.

Good relationship prompts new Volvo EC220D crawler and EW140D wheeled excavator

based David Smith Contractors Ltd has added yet more Volvo excavators to its increasing fleet of Volvo Construction Equipment products thanks to continuing Fgoodraserburgh relationships, good product reliability and operator preference.

Good relationship Established back in 2002 by Proprietor David Smith, the Company has evolved as a civil engineering and groundworks contractors undertaking bespoke projects for blue chip companies such as major retail outlets and superstores as well as the important oil and gas sector in the north of Scotland. Having purchased their first Volvo just six years ago, the Company has added to its portfolio of Volvo equipment with seven articulated haulers, two L120Câ&#x20AC;&#x2122;s and an L150C loading shovels, and numerous excavators ranging from the compact EC55B up to the EC290C. Just recently the Company has invested in a new Volvo EC220D crawler and an EW140D wheeled excavator. â&#x20AC;&#x153;We continue to have an excellent relationship with team from Volvo and the machines have been

reliable and productive as well,” explained David Smith. “The opinion of my operators is equally important and they appreciate the high standard of operator comfort and overall performance we’ve found with the machines.” The latest models to join the fleet herald new ventures that David Smith Contractors are entering into such as demolition contracts, crushing and quarrying contracts, piling and major multi million pound groundworks contracts. “Moving into these areas and to be able to offer our client base a complete package of services is vital for the long term,” said David Smith. “And to carry out the work in a cost effective manner means increasing the size of the machines and their capacities in terms of lifting and hydraulic capacity to suit the applications. In doing so we’ve become a one stop solution for our clients.” For instance the new EW140D delivered to David Smith Contractors features Volvo’s two piece boom arrangement and is the very first Volvo excavator to be supplied complete with a factory fitted Steelwrist tiltrotator and a Cambus derived Xcontrol G2 operating system. This combination offers a very versatile and specialised machine giving a high degree of manoeuvrability for a whole range of applications. This is just one example but it follows an approach David Smith has taken in diversifying his business for some time as he evolves his business. Last year for example he modified a new Volvo EC240C to accept a bespoke piling rig which includes the fitting of an Indexator rototilt hitch and a hydraulically driven sheet piling head of the company’s own design and manufacture. The two tonne

Issue 04 | 2012

head runs off the EC240C’s hammer shear circuit requiring up to 230 litres per minute in high mode and can handle sheet pile sections up to 14 metres in length at a reach of 7 metres. Another initiative has been to equip half his fleet of 30, predominantly branded Volvo excavators with GPS for bulk earthmoving, profiling, digging foundations and hard landscaping jobs. David Smith Contractors provides a complete range of Civil Engineering Services from demolition and earth moving to petrochemical site maintenance and road construction. Most recently the company has won prestigious contracts from leading supermarket chains for stores built in Inverness and Nairn, the runway extension at Aberdeen airport and the new prison at Peterhead.

Midlands Leading Construction Supplier JPE Aggregates Invests in CDE Plant Upgrades Investment in CDE Plant Upgrades For over 20 years, JPE Holdings Ltd has grown to develop its business of supplying aggregates, groundworks and site clearance, becoming one of the Midlandâ&#x20AC;&#x2122;s leading suppliers to the construction industry. In the winter of 2010, the company invested in a CDE mobile washing plant for operation at their Elford Quarry site in Tamworth, which included an M2500 E3, an A400 Aquacycle Thickener and an Aggmax 150 for feeding, screening, sandwashing and stockpiling. This equipment has enabled them to produce a high quality range of fully washed recycled aggregates including sand, 40mm, 20mm and 10mm gravels, all of which are recovered from fully sustainable sources which are supplied to the local sand and aggregate market. The following winter saw JPE Aggregates upgrade to the A600 Aquacycle Thickener and recycling hopper to essentially increase throughput levels.

Issue 04 | 2012

As operations and productivity grow, JPE have recently unveiled a move to a new site at Shire Oak, Walsall, West Midlands. Due to the quality and perceived longevity of this new site, JPE will undertake a move of the existing A600 Aquacycle Thickener and the Aggmax 150. The company will also upgrade the current control panel and install a new M2500 4EX mobile washing plant for the production of 2 types of washed aggregate and 2 types of washed sand. The Shire Oak site will accommodate the disposal of inert waste from the local area, allowing construction and demolition companies to avoid landfill tax. With the installation of the new CDE washing plant equipment, they will process the recycling material, creating high quality aggregates for resale to the construction industry. Managing Director Steve Birch comments â&#x20AC;&#x2DC;From our Elford Quarry, we were impressed by the capability of the M2500 and AggMax to produce high quality sand and aggregates from waste material and immediately saw how the system could be applied at the new Shire Oak site.

Digital Display Technology from CDE Improves Productivity for Jehander

CDE have recently developed a digital display screen in order to assist a customer in monitoring the productivity of their washing plant. Working closely with leading Swedish operator Jehander, CDE had to ensure they had a full understanding of the project requirements which included a digital feature that allowed them to optimise productivity. With one of the largest pit operations in Stockholm, producing sand, gravel, crushed rock and soil, Jehander ultimately wanted a mechanism to monitor the throughput levels of sand and aggregate being produced to allow them to achieve maximum productivity. Subsequently, CDE developed a controlled automation system which integrates fully with the operation of the plant itself and is used to set the tonnes per rate on sand and aggregate, in turn highlighting the need to increase the feed material if and where necessary. For Jehander, overall production improvements have amounted to approximately 15%. The controlled automation system allows visibility of production for the operator whilst allowing for raw material planning in terms of management to plan and supply the right mix of raw material to the plant. This system effectively displays tonnes per hour of material to the washing plant as highlighted on the top row of the digital display board as shown. The actual tonne per hour of sand and aggregate are also set individually on the HMI, indicating that the operator ideally should maintain

Issue 04 | 2012

the figure at 100% in order to fully maximise the washing plant operating tonnage. The digital display also features a mechanism that will allow the user to monitor the overall actual tonnage of material that has been fed through the washing plant over a certain time period which can be reset at the end of the day or week. Essentially, what this means is that when a plant is running and the sand level is for example at 60% with the aggregate running at 100%, this will highlight to the operator that finer raw material is required for feeding into the hopper in order to maximise overall plant productivity. The hopper will either increase or decrease speed to maintain the optimum level of 100% on aggregate and sand.

The official opening of the new CDE Asia factory in Kolkata, India will take place on Wednesday 21st November. The event will be attended by Lord Green, Minister of State for Trade and Investment with the UK Government.

New factory nearing completion for CDE Asia The new production facility will be located in the same industrial area as the existing CDE Asia factory in Kolkata and has been developed to ensure the company can accommodate growing demand for the range of washing equipment they produce for the market in India and South East Asia. A range of equipment from the CDE Asia product portfolio will be on display at the event including the M2500 mobile washing plant. Commenting on the new development Managing Director of CDE Asia, Mr Manish Bhartia said “Our new factory will allow us to build on the success we have enjoyed in India over the last five years and expand our territories into neighbouring countries. We have been exploring the development of a new partner network outside India and have won projects in Malaysia and Indonesia. The new factory provides the additional capacity and superior product finish capabilities to not only increase market share in India but enter new territories.” Since the formation of CDE Asia in 2007 the company has established a position as the leading manufacturer of washing equipment with numerous projects throughout India. The strategy that has driven this success has involved pioneering the introduction of new processing systems in a variety of industry sectors. Key to this success has been the adaptation of CDE equipment to suit the specific requirements of the iron ore industry. Many of the leading steel producers in India are now operating iron ore processing systems from CDE which have been developed over the last five years. “Our success has resulted from the capability of our systems to remove contaminants which cause significant

Issue 04 | 2012

inefficiencies in the steel production process” explains Dr Arabinda Bandyopadhay, President – Technology and Business Development at CDE Asia. “Our Kolkata base is our Global Ore Processing Knowledge Centre and will allow us to bring these systems to a wider global audience in the future.” Another recent success has been the introduction of a construction and demolition waste recycling plant for the Delhi Municipal Corporation. This is the first project in this sector for CDE outside the UK where the modular washing systems for construction, demolition and excavation waste were first introduced ten years ago. According to CDE Asia Managing Director, Mr Manish Bhartia the increased production capacity offered by the new factory in Kolkata will allow the company to contribute towards the delivery of the $1 trillion infrastructure investment recently announced as part of the 12th Five Year Plan which runs from 2012 to 2017. “With the opportunities that will present themselves in the coming years we are now ideally positioned to help build a better future for everyone in India by focusing on faster, sustainable and more inclusive growth.” CDE Global Ltd Peter Craven Tel.: +44 (0)28 8676 7900 eMail: pcraven@cdeglobal.com

Bohr- und Sprengtechnik 21. und 22. Januar 2011 in Clausthal- Zellerfeld

rs e ap p r o f l l a c Profil Die erstmaligen Sprengarbeiten im Bergbau des Oberharzes im Jahre 1632 und die schnelle Ausbreitung der neuen Gewinnungs- und Vortriebstechnik in den Bergwerken um die damals selbstständigen Städte Zellerfeld und Clausthal können als einer der epochalsten Meilensteine in der Entwicklung der Bergbautechnik angesehen werden. Die ständige Weiterentwicklung über die Einführung der brisanten Sprengstoffe im Harz sowie die Erfindung des Dynamits im Jahre 1866 bis bin zu den hochmodernen Anwendungen im über- und untertägigen Betrieb der Rohstoffgewinnung zur heutigen Zeit waren und sind ein Garant zur Leistungsfähigkeit moderner Betriebe. Dabei war auch schon in den vergangenen Jahrhunderten stets von großer Bedeutung, sich über den Stand der Technik auszutauschen, um Innovationen oder Weiterentwicklungen zu verbreiten und abermals voranzubringen. Der langen Tradition der Clausthaler Kolloquien folgend, veranstaltet das Institut für Bergbau im Januar 2013 das dann bereits 18. Bohr- und Sprengtechnische Kolloquium in der Aula der Technischen Universität Clausthal. Seit dem Jahre 1976 werden zweijährlich etwa 300 Fachbesucher aus

Issue 04 | 2012

den Bereichen der Bohr- und Sprengtechnik im Oberharz erwartet, um sich über die neuesten Entwicklungen auszutauschen, Fachgespräche in der angeschlossenen Ausstellung zu führen und den Abend gemeinsam in geselliger Runde auf dem traditionellen Bergmännischen Abend ausklingen zu lassen.
