New QdX4 mill drive systemMining Magazine
explained that in the past grinding mills operating between 18MW and 28MW required a large electrical wrap-around motor known as a gearless mill drive (GMD). The QdX4 mill drive system is an alternative option to the GMD. Until now the gear-driven solution for large SAG and ball mills was limited to 18MW.
