The two installed mills include a semi-autogenous (SAG) mill measuring 10.4 x 6.1 m with a drive output of 15 MW; and a ball mill rated at 18 MW. The SAG mill reduces ore fragments with a maximum size of 250 mm (P80 = 152 mm) down to 2 mm, and the ball mill reduces the SAG mill product to about 74 µm. Grinding is followed by flotation. read more

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically 120 percent of the normal drive torque.
