mill. However, recent SAG mill designs now include a single pinion drive that is used to transmit MPa (7500 hp) to a mill. Consequently, it is now possible, with a twin pinion drive, to have power transmission delivering I MPa (15,000 hp) to a mill. This power level is now approaching that available through the gearless drive system.

ABB's GMD is the most powerful mill drive system in the market to power semiautogenous (SAG), ball and autogenous (AG) mills, This 'workhorse' for grinding operations combines a robust, servicefriendly and fit for purpose design to provide highest throughput, reliability and availability for your processing plant. eBook: Grinding ...
The SAG mill drive package is rated at 21 MW; the ball mill drives at MW. • An order in May 2008 valued at more than €20 million from Aurox Resources Ltd. to supply gearless drives for a 34ftdiameter, 14MW SAG mill and a 26ftdiameter, 17MW ball mill for an iron ore project in Western Australia.
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. To meet these increasing demands, ABB developed low ...
