Aug 01, 2001 The specific power consumption for these two ball shapes is shown in Fig. 16. For N≤75% there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the non circular balls falls off rapidly.
