Voith release new fluid coupling TurboBelt 780 TPXL for high powered belt

first_imgVoith have developed a fluid coupling technology, specifically designed for drives on open-pit mining belt conveyors named TurboBelt 780 TPXL. The development of an XL blade wheel profile is said to deliver twice the power compared to previous couplings of similar size. It has been designed for 6- and 8- pole induction motors operating at speeds of 900 to 1,200 rpm. On start-up, there is a precisely controlled introduction torque to protect the belt and the driveline. Start-up times of up to several minutes can be individually set in the control system.In May 2012, the initial start-up of this new fluid coupling was in one of the biggest sea terminals in northern Brazil, where iron ore is shipped worldwide. In order to handle the increasing amount of iron ore, the operating mining company decided to install three TurboBelt 780 TPXL couplings in the drives of a 1,451 m  long conveyor. As the conveyor transports around 10,000 tons of iron ore every hour, its reliability has high priority for the mining company. The maintenance efforts can be reduced to a minimum as the hydrodynamic power transmission is completely wear-free. Compared with traditional couplings, the TurboBelt 780 TPXL requires reduced installation space and is also lighter. This has enabled a simple and quick installation and alignment in the Brazilian sea terminal in May 2012.last_img
