# power consumption in ball mill

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.

## Ball Mill Design/Power Calculation

Jun 19, 2015 · If P is less than 80% passing 70 microns, power consumption will be; Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns).

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.
