Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being fi .
The price of a motor depends on the rated torque of the motor (more-so than the motor rated power and diameter), so for large mills a slight increase of the motor rated speed can result in substantial price savings. Operating at higher mill speeds can reduce operating costs by permitting operation at lower ball charges for a given mill power draw.
