thyssenkrupp: efficient equipment for entire coal handling process
Coal represents a major portion of dry bulk which is transported around the globe today. Alongside other fossil fuels such as natural gas and oil, it remains an important source of energy in many parts of the world. The production of steel still depends on coke, which is one of the most important products derived from hard coal. Coal tar, a by-product of the coking process, is an important raw material for the chemical industry. The aromatics and carbolic acid which are derived from it, are used for the manufacture of a variety of plastics and dyes. Both ammonia and methanol can be synthesized from brown or hard coal, while fuels are produced with coal-to-liquid processes. These industrial processes rely on a reliable logistics network that links the mine with the plant. The need for long-distance transport has led to the development of specialized rail and port infrastructure for import/export terminals. Coal deposits are often located in more remote areas and transport by train or ship becomes necessary to feed the plants and power stations. Countries which do not have their own coal deposits, or where the coal demand exceeds national supply, need to import the coal they require by sea. The vessels bringing the coal are loaded at export terminals which are equipped to receive the bulk material from open pit mines and transfer it onto ships. Import terminals have to be developed to unload the coal and direct it onwards to the industrial user. thyssenkrupp Mining Technologies is one of only a few companies in the world

able to supply the plant and handling equipment covering the entire logistical network from mining, to the transportation and handling of coal. In the mine this encompasses bucketwheel excavator systems, in-pit crushing systems and belt conveyors. Further down the line there are train loading and unloading stations, stockyard equipment, blending beds, shiploaders and ship-unloaders as well as conveyor systems within power plants, steel mills and other industrial plants.
At various nodes, stockyards function as a temporary storage facility for the material and also act as a buffer between different modes of transport and plant processes. Specialized machines perform the task of stacking the material onto stockpiles, and Shiploader at an export terminal.

reclaiming it again when required.
The design of the stockyard and the machine types which are selected depend upon the process and function of each particular facility and its unique local requirements, climatic conditions and restrictions. Stockyard layouts at harbours, for example, are generally subject to tight spatial constraints and are required, from an operational perspective, to minimize the time required for loading a ship. For this reason, they tend to use high-capacity bucketwheel stacker-reclaimer combinat ion machines. By contrast, a power station requiring lower throughputs and subject to strict environmental constraints due to its proximity to urban areas, may opt for a circular stockyard which is completely covered with a roof to minimize noise and dust emissions. Strict regulations may also motivate the selection of pipe-conveyors inside such a power plant because the material is not exposed to the environment. At mines or chemical plants, where the composition of the material must be controlled according to the requirements of the end user, stockyards are used for homogenization or blending different grades of material. In such cases machines such as bridge or drum reclaimers are employed because their mode of operation yields the best results. In each case, the stockpile design and stacking method must be selected to suit the particular application.
The rail network functions as an efficient link between mine, harbour and

plant. Rail loading stations transfer the material onto trains for outward transport, while ensuring the optimal filling of individual wagons. At the destination, the unloading of the train is done by tippler systems which tip and discharge the material from the wagons. The design of the installation and choice of a suitable tippler depends on the specifics of the application. Tipplers are constructed in a number of different geometries, with implications in terms of cycle time, plant infrastructure and compatibility with rolling stock. Side-tipplers are generally less costly to install, while rotary tipplers are selected for high-performance applications requiring higher throughputs. At terminals for transshipment, the latest rotary tippler installations can unload four wagons simultaneously without the units being uncoupled from the train. With such machines, the whole unloading process can be automated to a high degree if the appropriate logistical arrangements are made.
At the export terminal, the material supplied by the mine is temporarily stored

in the stockyard. The stockpiles are generally segregated on the basis of origin and grade of material, a procedure which allows the product of a particular supplier to be dispatched to the correct customer, or for the mixing and homogenization of different qualities according to customer requirements. When a ship arrives at the harbour, the material earmarked for that shipment is transferred from the stockyard and loaded onto the waiting vessel by means of a shiploader. thyssenkrupp offers the full range of shiploader configurations to cater for most customer requirements; this includes radial, slewing, co-ordinate, linear and stationary type machines. Port handling equipment must be designed to perform a range of motions and adjustable reach to ensure sufficient flexibility for each particular application. This is important because the machine must cope with the full range of shipping that can be expected, both in terms of size and configuration. For coal, the ship size tends to vary from 35,000dwt to 250,000dwt. High capacity machines are required for coal export to minimize the time vessels spend in the harbour and the resulting costs.
The function of the import terminal is to unload the incoming cargo vessels and dispatch the product to the next destination, whether by road, rail or ship. Various types of specialized machines can be used for the unloading of ships, with the choice of suitable equipment depending on factors such as material properties, product variety and throughput that must be handled. Continuous unloaders, equipped with bucket elevators, are excellent for handling coal and operate at a high level of efficiency. The time lost in the manual cleaning of the hold is kept to a minimum through careful optimization of the unloading procedure. Where a greater variety of materials must be handled, grab unloaders offer greater flexibility; in some cases, the machines may even be used for loading vessels. The unloading process of grab unloaders is more time consuming, however, due to its cyclical nature.
In conclusion, it must be restated that coal remains an important raw material for a large number of industries globally. This generates a continued demand for logistical infrastructure to transport coal from the mine and deliver it to the end user. thyssenkrupp offers its customers a complete service, relying both on its vast experience in this field whilst also remaining committed to innovation and the optimization of its products; a partner that forms a vital link in the path from pit to plant.

COAL IS TRANSPORTED BY TRAIN FOR PROCESSING AND TRANSFER TO STOCKYARDS IN BULK PORT TERMINALS. Coal is transported in rail wagons that are moved by ‘wagon pushers’ moving the wagons under hoppers to load material or to wagon dumpers for unloading. So far, those pushers were diesel powered, but in this area, too, a reconsideration of solution approaches is taking place.
Conductix-Wampfler is strengthening partnership with OEMs and end-users

SPECIALIZED IN COAL HANDLING Coal represents a significant volume of the bulk product handled in ports; historically, it’s been one of the star materials more usually handled by grabs and therefore, grab solutions have suffered a continuous evolution and specialization to improve this material’s loading cycles.
Based on a 0.8–0.9 T/m3 average density, the Blug range for coal handling offers a wide variety of options depending on the crane and capacity requirements. The key factor to obtain a fast return of investment for this kind of applications is to optimize grab’s capacity/self weight ratio and offer the highest lifetime versus purchase, start-up and maintenance costs.
The C4, CV2 and CM4 grabs are the most representative models of Blug clamshell grabs for coal and bulk handling applications.
RECENT COAL HANDLING PROJECTS In terms of coal handling deliveries during 2021, BLUG supplied a 13m3-capacity rope-operated clamshell grab for a Romanian port and two 20m3-capacity rope-operated clamshell grabs for the Spanish market.
Currently, ten more four rope grabs are being tendered for different international ports.
STORMAJOR® application prevents spontaneous combustion in coal stockyards
In cooperation with AUMUND Asia (H.K.) Ltd (China), responsible for the Asian Sales Area, SAMSON Materials Handling (AUMUND Group) has recently supplied a STORMAJOR® 2.0 to a Japanese company for the handling of coal at its chemical plant in Indonesia. The site, located in Banten province, is a specialist manufacturing facility producing various chemicals for the global supply chain. Coal is delivered by seagoing vessel, then it is offloaded and stored in the facility directly. During storage, the coal can spontaneously combust due to its quality. The STORMAJOR® designed and delivered by SAMSON manages the continuous in- and out-loading of the coal, whereby the coal is cooling down and hot spots will be avoided.
The situation before: in 2018, a coal fired power plant was opened to support the chemical manufacturing operations. This 2 x 151 MW facility is located on the periphery of the production plant with its own covered coal stockyard. The environmental conditions, if not ideal, can cause hot spots of burning fuel. These hot spots, if left untreated, can spread, resulting in a potentially dangerous situation and a loss of usable product. To combat this, the operating company has been using a combination of excavators and dump trucks to move the coal out from the covered storage area to an external uncovered stockpile. Once the coal has cooled down, the reverse process occurs and the excavator loads a dump truck to take the material back into the covered area before another excavator manoeuvres the material back onto the covered stockpile. This movement, along with manipulation from an excavator on the external pile allows any hot spots to be dealt with.
Prior to the purchase of the SAMSON STORMAJOR® 2.0, a number of excavators and dump trucks were being used to move the material, this double handling was time consuming and tied up a lot of resources. They identified a need to simplify this process and worked with AUMUND Asia and SAMSON on providing a simple, cost effective and reliable solution, a STORMAJOR® 2.0.
The situation today: after detailed review by SAMSON product specialists, a track-mounted, self-powered, 450 series STORMAJOR® with a 27m boom was selected. The STORMAJOR® could be positioned with the reception feeder inside the facility and the boom outside allowing the excavator to load the material transported outside directly onto the coal pile. Keeping the STORMAJOR® in place and turning the machine around, it could subsequently feed cooled coal back inside onto the covered stockpile. The versatility of this machine allows the company to reduce the number of truck movements and the number of personnel needed in the coal facility, thus reducing operating costs, increasing material yield and improving operator safety.
The STORMAJOR® is the Samson® Material Feeder combined with an outloading boom conveyor, which can slew and luff. The feeder and boom are combined into a single mobile machine. Mobility is achieved via self-powered tracks for uneven terrain or wheeled units designed to be towed. Three different types are available on the feeder section to enable the handling of light to heavy bulk materials. The modular outloading boom can be up to 27m long and achieves stockpile heights of over 11m.
Dust control can be achieved by fully enclosing the material feeder and belt conveyors then employing integral filter units mounted on the feeder and boom. In addition, for certain applications a telescopic discharge chute can also be fitted to the boom to allow dust free loading.
The feeder is able to accept material delivered by numerous methods such as a front end loader, tipping truck, mining dump truck, grab and excavator. This makes the STORMAJOR® a truly versatile machine with various applications including stockpiling, barge or ship loading, rail wagon loading, transfer or emergency material feeding.

Its high-quality braking equipment offers customized stop-action solutions for a wide variety of industries from sea to sky, and everything in between. For decades DELLNER BUBENZER products have been recognized worldwide as innovative braking solutions that are precision engineered to meet the highest quality standards.
As a multinational global company, DELLNER BUBENZER is also a local partner with manufacturing facilities located in Sweden, Germany, Poland, Italy, Denmark, Czech Republic, India, USA and China, as well as sales and service divisions in Holland, Singapore, Malaysia, Dubai, Brazil and Argentina.
DELLNER BUBENZER manufactures a range of industrial brakes and brake-related products like storm brakes (rail clamps and rail brakes, wheel brakes), monitoring systems, couplings, brake discs, hydraulic power units and safety systems to protect the steel structure of the machine against overload and snags.
DELLNER BUBENZER’s multinational manufacturing capabilities across the world, paired with local impact under one united front, strengthens DB’s loyal customer base. Furthermore, due to the continuous development of the product line and the service network, the customer base is continuously growing.
QUALITY PRODUCTS Most of the parts are made in-house on new CNC machines, with production in the company’s different facilities. Furthermore DB runs one of the biggest dyno stands for industrial brakes in Europe. All brakes are put through their paces before they are released to the market. When it comes to quality standards DB runs a final check with every brake leaving the factory. In addition, the company works with its quality assurance and development team to constantly optimize its products. In its own development centre, DB has one of the largest test benches in Europe, where it puts the existing product range and all new developments through their paces. Compliance with its own quality requirements has the highest priority, which is reflected in the longevity of the products.
DB’s Torque scales are exactly calibrated. DB is one of the very few companies that is able to provide both brakes and thrusters. This means that the set-up of the brake matches the thruster’s capabilities exactly and vice versa. Since DB has the ‘strongest thruster’ in the market, brake performance is far better than with conventional technology.
DB is not only a brake manufacturer, but also a system supplier, for example safety systems to protect huge steel structures against overload, monitoring systems and more.
The company’s internal global service team also receives regular training. In addition, DB also offers external training at its customers’ sites, so that employees learn how to use its products in the best possible way. Throughout the new DB has continued to maintain sales and service in the challenging environment of the Covid-19 pandemic. To help support customers remotely, DB has been making use of VR glasses. These are connected

glasses that link personnel to DELLNER BUBENZER experts over the internet. The DB service team can look at the application, its monitoring system and the brakes directly and guide staff through the necessary maintenance and repair steps.
CUSTOMERS DB’s customers include all well-known OEM for huge equipment like conveyors, ship- (un-) loaders, stacker, stackerreclaimer, bucket wheel excavators, ball-, SAG and AG mills, process equipment etc., but also end-users like huge mines and bulk terminals worldwide. Coal is just one of the many commodities kept in control by systems from DB.
DELLNER BUBENZER CASE STUDY
In this case study, DELLNER BUBENZER recently supplied brakes for three gearless conveyor systems with an installed capacity of 2 x 5,500kW each for 7,100 tonnes per hour for a copper mine in Mongolia.
The scope of supply was including floating calliper brakes SFR50, brake discs, hydraulic power units, UPS, BCC3000 closed loop control systems as well as the complete encoder technology. The main parameters of the brake like pad wear, stroke (air gap) and brake pad temperature are continuously monitored.
The brakes stop the conveyor within 10s in loaded or unloaded condition. Depending on the parameters, like load, speed etc., the HPU and control unit provide different braking levels and scenarios. The controlled braking process minimizes the conveyor belt tension and reduces stresses in the connected equipment. The system is also able to perform the pre-programmed ramps and stopping curves after a power outage.
Redundant controls and HPUs guarantee highest system availability. The environmental conditions need a compact set-up of the brake units. The spring applied, hydraulically released, fail-safe brakes are able to equalize axial movement of the connected shafts.
VISUALIZING AND MONITORING OPTIONS Communication between main PLC and BCC3000 goes via PROFIsafe protocol integrating the relevant safety features while also monitoring the subfunctions.
In summary, DELLNER BUBENZER’s products offer a safe and durable braking solution.
NEW PRODUCTS In January DB launched its new disc brake SB28.5. This brake is one of DB’s first brakes, which it has been building since 1980, and which is constantly technically developed.
With this model, DB has also set new market standards in combination with its own thruster, the BUEL. Sustainability is a driving force in development for DB, with the combination of the SB 28.5 with the BUEL® thruster.
This is an important development for braking systems that consumes less energy with a fast-closing time. Beyond sustainability and energy saving, the SB 28.5 brake presents the significant advantage of less maintenance.
This new braking system underscores DELLNER BUBENZER’s commitment to uphold our pioneering reputation and deploy the latest in technology to mirror what market needs, and its clients deserve. And DB’s customers can look forward to great new developments this year.
