Do more with less go gearless. Mine operators are challenged with moving more material on conveyors that may cover distances in the tens of kilometers and ascend steep gradients. To increase overall reliability, mining companies also want fewer transfer stations between conveyors, which may require wider and longer belts.a pilot project with the title “gearless conveyor drive with PM motor,” with Lausitz Energie Berg-bau AG (LEAG) in the Jänschwalde open-pit lignite mine close to Cottbus in Germany.

Gearless Belt Conveyor Drives New Technology for high

When it comes to drive sizes exceeding 3500 kW per individual drive, there are no conventional drives with electric motors and helical bevel gears. Gearless drives, like those implemented for mine hoists in underground mining operations, allow the use of larger drive units and are increasingly being utilized to drive belt conveyors.Powered by Siemens’ new gearless drive technology, thyssenkrupp’s high-capacity overland conveyor will access one of the world’s largest copper reserves in Quellaveco. The Quellaveco mine in Peru contains approximately 7.5 million tons of copper in ore reserves enough to wire 80 million homes or equip 90 million electric vehicles.Siemens’ gearless drive technology powers high-capacity

Efficient TAKRAF belt conveyor technology at one of the largest

In order to achieve this feat, it was necessary to use newly developed components that redefine the performance limits of belt conveyor technology. St 10 000 quality conveyor belts were used for the first time. Operating belt safety ratings of S = 5.0 required belt connections with a reference fatigue strength of over 50 %.are eliminated. Gearless drive systems need less instrumentation and they also fit into a smaller footprint, which is very important when space is restricted.” Designing the motor to match the conveyor Each heavy-duty conveyor system is unique.
