Aug 01 2001 the specific power consumption for these two ball shapes is shown in fig 16 for n75 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 noncircular balls falls off rapidly
The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level this demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in dem modelling
