fundamentally different from a ball mill. the impact mechanism and long residence times in ball mills cause indiscriminate grinding and poor size distributions. this generates slimes, wastes energy and increases reagent consumption. furthermore, closed circuit cyclones used in ball and tower mill circuits use considerable amounts of energymill 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
