Maximize availability and productivity. The gearless mill drive eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
Eleven 5MW gearless drives with synchronous motors running at low speeds 50-60rpm drive three conveyors two with four motors each and one with three. Two 20MW conveyors transport the ore from the open pit operation to the surface, overcoming an elevation change of around 1,300m, while the second conveyor feeds into a slightly smaller, 15MW, overland conveyor.
