STEPPING FORWARD: USING VARIABLE SPEED DRIVES

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
