Voith's 1,000th TPKL Fluid Coupling Goes to a Chinese Belt Conveyor Drive
December 29, 2014
Voith recently manufactured their 1,000th fluid coupling type TPKL. The coupling will go to the DaTong Coal Mining Group in China. The fill-controlled fluid couplings will be used in a 6.4 MW belt conveyor drive. The 3.160 meter long underground belt conveyor is driven by four 1.600 kW motors, with a planned capacity of 4,000 tons per hour. The belt conveyor will transport coal uphill at a 14 degree angle.
“We are very happy to use fill-controlled couplings from Voith running in our belt conveyors," said DaTong's Manager of the Mechanical and Electrical Department.
Voith started the production of the TPKL coupling series in 1997. This fluid coupling type was especially developed for demanding belt conveyor applications in mining. The coupling type provides t torque limit-tion for a smooth start-up of the belt conveyor. It allows active load sharing with multi-motor drives.
DaTong Coal Mining Group Co., Ltd. is located in DaTong City, a province Shanxi, China. It is one of the top three coal groups in China, with a coal production capacity of 152 million tons per year. The coal group operates a large number of coal mines across the country. Many of them use Voith
fluid couplings in diverse underground applications like AFCs, belt con-veyors, stage loaders and crushers.
