New fluid coupling TurboBelt 780 TPXL from Voith raises the productivity of high powered belt conveyors.
Developed especially for the drives on open-pit mining belt conveyors, the
latest fluid coupling technology from Voith provides a lot of benefits.
Thanks to the innovative XL blade wheel profile, the TurboBelt 780 TPXL
coupling 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 belt conveyors are started reliably. Start-up
times of up to several minutes can be individually set in the control
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
(4,760 feet) long conveyor. The couplings assure smooth operation and avoid
unscheduled downtimes of the belt conveyor. As the conveyor transports around
10,000 tons of iron ore every hour, its reliability has high priority for the mining
company. When combined with reliable mechanics, the hydrodynamic TurboBelt
780 TPXL coupling provides extremely high system availability of up to 99.8 %.
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 only half as much installation space and is also significantly lighter. This has enabled a simple and quick installation and
alignment in the Brazilian sea terminal in May 2012.
Altogether, the new TurboBelt 780 TPXL couplings raise the productivity and
profitability of the belt conveyor. Besides the couplings, the mining company
benefits from a customized package also delivered by Voith.
