ball mills on the other hand, as far as process requirements are concerned, did not require variable speed. however, frequency converter based drive systems provide benefits that improve the ball mill operation. fixed speed configurations the key issue to operate a mill mill speed influences the power draw in two ways: on the one hand, mill power is the lineal product of the mill rotational speed and the torque applied, so there is a lineal dependence; on the other hand, the centreof gravity of the charge is shifted withspeed, creating a non-lineal dependence. the
