bauma 2013 continued ThyssenKrupp Resource Technologies ThyssenKrupp used bauma 2013 as a platform to discuss the merging of two engineering subsidiaries that work closely with the mines: ThyssenKrupp Fördertechnik and ThyssenKrupp Polysius. The new group will now be known as ThyssenKrupp Resource Technologies. With around 5,500 employees and annual sales of about €2 billion, the new company will be one of the world's largest suppliers for mining, mineral processing and bulk materials handling systems. It will offer single-source expertise ranging from design and consulting to engineering and project management to construction and installation, after-sales service, research and development, and plant financing. Dr. Hans Christoph Atzpodien, CEO of the Industrial Solutions business area of ThyssenKrupp AG, discussed the strengths of the new company. "Our comprehensive engineering know-how covers solutions from single machines to complete plant," Atzpodien said. "With growing environmental awareness and rising raw material and energy prices, this engineering expertise provides our customers with a significant competitive edge." The management board of ThyssenKrupp Resource Technologies now consists of Ramsis Shehata (CEO), Christof Brewka (service business), Heike Franke (CFO), Martin Hilbig (CHRO) and Lothar Jungemann (cement business). The group's product range includes bucketwheel excavators; conveyor systems; crushing, grinding and processing plants; stockyard and port handling systems for bulk materials; as well as cement plants. Lifecycle support can be provided for all products, as well as 24/7 service for individual machines or plants. MTU Showcases Engines & Gensets The Tognum Group presented its MTU diesel engines and MTU Onsite Energy gensets that deliver outputs from 100 to 3,000 kW and are able to meet the EU Stage IV and the U.S. Environmental Protection Agency Tier 4 final emissions regulations that will be coming into force in the future. In the open-air area of the show (45A, section 106), MTU Onsite Energy demonstrated its diesel gensets for power generation. For power outputs under 560 kW (underground vehicles), MTU presented its 4- and 6-cylinder Series 1000 inline engines and 6-cylinder Series 1100, 1300 and 1500 inline engines. Equipped with SCR, these engines comply with the EU Stage IV and EPA Tier 4 final requirements to apply from 2014. From 2014, 10 and 12-cylinder Series 1600 units will be extending the engine range available up to 730 kW. These offhighway engines are suitable for use in haul trucks, wheel loaders, pump drives and mining vehicles. They meet EPA Tier 4 final requirements through the use of high-pressure common rail injection, two-stage turbocharging, and exhaust gas return with cooling system. To keep fuel consumption as low as possible, MTU has focused strongly on optimizing combustion processes. MTU's 12V4000 diesel engine. Overall, customers benefit from the low operating and conversion costs of the integrated system. MTU's product portfolio also includes 12- and 16-cylinder Series 2000 engines covering outputs from 567 to 1,000 kW for use in mining vehicles. EPA Tier 4 engines using in-engine technology are only available in the 783 to 970 kW power range. MTU supplies Series 4000 engines with 8, 12, 16 and 20 cylinders for outputs up to 3,000 kW and these meet the EPA Tier 4 legislation that applies in the U.S. without the need for exhaust after-treatment. A new addition to the line is the 12-cylinder Series 4000 version that is compliant with EPA Tier 4 interim rules. These engines are built for long-term service in wheel loaders, excavators, haul trucks, construction machinery for underground mining applications, and in heavy-duty mining vehicles for operation in surface mines and stone quarries. MTU's renowned Series 2000 and 4000 units continue to be available for countries with higher emissions thresholds. Fluid Coupling for High Powered Belt Conveyors It's a large spindle for a crusher, but it's not the largest spindle ThyssenKrupp Resource Technologies makes. June 2013 Voith displayed the TurboBelt 780 TPXL, a fluid coupling developed for large conveyor drives. An innovative XL blade wheel profile transmits twice the power previous couplings of similar size could achieve. It is designed for 6- and 8-pole induction motors operating at speeds of 900 to 1,200 rpm. The start-up with precisely controlled introduction of torque not only protects the belt, but also the entire driveline. Even overloaded conveyors can be started reliably. Start-up times of up to several minutes can be individually set in the control system. This new fluid coupling was first put to the test in May 2012 at one of the largest iron ore terminals in northern Brazil. The operator decided to install three TurboBelt 780 TPXL couplings in the drives of a 1,451m (4,760-ft) long conveyor. The couplings and conveyor system operated smoothly. As 35
