Electric Drives for Large Ore Grinding Mills

The mill operating speed of a geared drive is usually fixed by a constant speed motor and must be preselected. That speed decreases as the mill diameter increases, thereby increasing the transmission and drive problem. Since speed has such an effect on grinding, production, mill wear, and resultant costs, it must sometimes be changed after ...
