68 VDMA | 2014 VDMA MINING SUPPLEMENT VDMA to a fineness of 20% R DIN 0.09 mm. The mill motor for both ver- tical mills, type LM 26.3 D, will have a capacity of 780 kW. Loesche's scope of supply for both coal mills LM 26.3 will also include two gearboxes and two hot gas generators (HGG), type LF 20. Each will be equipped with a multiple lance burner (MLB) and a start burner. Paul Wurth S.A. will be handle the Dniprodz- erzhynsk coal project and anticipates delivery of the Loesche mills for July 2014. Mobile Conveying Equipment Uzbekcoal has launched a comprehensive program to modernize and improve the output of Uzbekistan's most important open-cast mine at Angren. According to the company, coal production, which in 2010 amounted to 3.2 million metric tons per year (mt/y), should increase to 6.4 million mt/y by 2015. The Magdeburg-based FAM, a manufacturer of mining and convey- ing systems and equipment, is largely involved in this process by sup- plying mobile equipment for overburden and coal handling and conveying. The total weight of the FAM equipment to be delivered for this project amounts to approximately 5,000 mt. FAM will provide three units designed for conveying overburden with a throughput capacity of 4,000 mt/h each. Furthermore , each system consists of a crawler-mounted crusher and a mobile conveyor bridge. The relevant spreader with tripper car is designed for 12,100 mt/h and capable of managing the material from three faces. The entire system is completed by four 800-mt/h belt wagons with hopper and cable-reel cars for transporting the coal to the bench belt conveyor. The mobile crushing plants are designed for a throughp ut of 5,250 mt/h each. They consist of an undercarriage with two steer- able twin crawlers. The machine's frame is supported on the under- carriage in a statically determined manner. Furthermore, a feed hopper, an apron feeder, a heavy-duty double roller crusher and a discharge belt conveyor complete the system. Shovel excavators feed the systems and ensure conversion of the discontinuous flow of ma- ter ials into a continuous flow. Moreover, they also crush the material to grain sizes facilitating conveying on belt conveyors. The crushers are designed for high compressive strengths (up to 200 MPa) and can process rock up to 1.1 m in diameter. The height-adjustable discharge belt conveyor of the mobile crushing plants transfers the material onto the mobile conveyor bridges. The latter are 90-m long an d designed so that the mate- rial can be transferred onto the bench belt conveyor in a large range of angles and from three different crusher working levels, which can be positioned between -15 m and +15 m relative to the level of the bench belt conveyor. This way a total working range of 45 m is available. The conveyor bridge, which can be hydraulically leveled, is sup- ported at both ends on a twin c rawler mounted undercarriage. At the discharge head of the conveyor bridge, the crawlers are arranged on both sides of the bench and the material conveyed is transferred to the bench conveyor between the crawlers. The electric power re- quired for the conveyor bridge and the crusher is supplied via a cable drum, which is connected to this undercarriage. Neither a change of the working level nor turning around at the tail station of the bench belt conveyor require decoupling of the system, i.e., the mobile The Loesche LM 26.3 D mill grinds coal to a very fine consistency.
