VDMA 28 VDMA MINING SUPPLEMENT • 2017 Last year was a big year for thyssenkrupp Industrial Solutions. They announced several new pieces of equipment and services at bauma and MINExpo. Then the company embarked on a reorganization plan where its business units were restructured and focused more strong- ly on sectors and customer groups. All of these moves were not only made to reduce costs and improve service, but to also consider step changes as to how projects are engineered and managed. "We now have a dedicated organization for project management and engineering and other central services regarding project execution such as commercial project management, logistics and procurement," said Thomas Jabs, executive vice president, mining systems for thyssenkrupp Industrial Solutions. "All of that is now combined into one entity, which is referred to as a Network of Excellence. The idea was to strengthen the focus of the company's core plant engineering business by combining all these project execution disciplines into one entity, making us more competitive and flexible in terms of resource utilization." thyssenkrupp Industrial Solutions has eight business units and one of those is Mining Technologies. Service is another business unit. "Ser- vice will be a cornerstone of the new organization," Jabs said. "The target is to offer our clients technical solutions as well as services for the whole lifecycle of a plant, and at the same time, to expand our local proprietary business. The service business unit will include service centers, spare parts business, upgrade refurbishments and asset management." The Mining Technologies business unit has three different op- erating units: mineral processing (crushing, grinding and pyro pro- cessing), materials handling (stockyards and port handling systems) and mining systems (continuous mining including the large crawler mounted machines and heavy-duty conveying including overland con- veying systems). "Each operating unit has global responsibility for its projects and products," Jabs said. "In the future, our performance will be solely evaluated by the combined global success of the project." This is a new concept within thyssenkrupp Industrial Solutions and they are eager to prove it will work. They recently submitted a proposal for two large conveyor systems for two different customers in Asia, most likely using gearless drive technology. New Approaches to Crushing Last year, thyssenkrupp unveiled the huge 63-130 gyratory crusher, first at bauma and then at MINExpo and the first two machines have been ordered. The crushers will be supplied as part of semimobile crushing plants for a copper ore mine. "The tendency with crushing in- stallation investments is to focus on operating expenses," said Frank Drescher, head of product division crushing technology, thyssenkrupp. "We are currently working on several in-pit crushing and conveying (IPCC) projects, and this new gyratory crusher, which is lower in weight and higher in capacity, represents a new path forward for us." One of those major projects that combines conveying systems and crushing plants is the Cuajone project in Peru. "At this instal- lation, a gearless conveyor serves one of the largest semimobile crushing installations in the world," Drescher said. When thyssenkrupp began development on the 63-130, they were expecting positive feedback because it opens new possibilities for plant design. "We can place in those modular plants a choice of crushers from the 75 to the 130," Drescher said. "That gives us a great deal of flexibility to respond quickly to requests." Many of the competitive mining-class gyratory crushers on the market today are being used for installations with concrete founda- tions. Other manufacturers were not as much concerned with out- of-balance forces, but thyssenkrupp had a keen understanding of them because they were using gyratory crushers to large extending semimobile steel structures. "That's where we have a tremendous advantage," Drescher said. "The extremely efficient operation of the gyratory crusher pro- longs the lives of these semimobile installations. With the 130, we have been focused not just to make the equipment bigger and more powerful, but managed also to reduce the forces substantially," Drescher explained. The semimobile installation avoids the concrete work to a great extent and allows for pre-assembly of large modules, which reduces the initial cost. "Further, these systems provide the option to relo- cate the crushing plant within the mine following the excavation and to reduce the truck fleet and cost involved thereof," Drescher said. "This could be the deciding factor for many projects." In the last 10 years, the majority of thyssenkrupp's underground crushing installations have been designed with gyratory crushers mounted in a stationary system, many of them with thyssenkrupp's split shell design to reduce component dimensions and weight for transportation. Most are complete systems that include conveyors and the company only sees that number growing. Material Handling: Moving Minerals Engineering Modern Crushing and Material Handling Installations Designing crushing and conveying installations, such as this truck dump, which handles two haul trucks, thyssenkrupp's semi-mobile installations avoid the concrete work to a great extent and allow for pre-assembly of large modules, reducing the initial cost.
