the two sag mills in the mission south mill each have two 3,000 horsepower electric motors. they can rotate in either direction which helps even out the wear on the steel liners inside the mill. when the rocks are about 38-inch or smaller, they are fed as a slurry into the two ball mills.
sep 01, 2016 this is attributed to the fact that the slurry pool on the opposite side of the rising ball media would counter the torque required to rotate the mill shell and lift the ball media, leading to a decreased mill power draw. therefore, unlike the agsag mill, the power draw data cannot be used as an indicator of overfilling for an overflow ball mill.
