## Charge behaviour and power consumption in ball mills

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.

## Charge behaviour and power consumption in ball mills

Some changes increase the shear strength leading to higher dynamic angles of repose of the charge, higher shoulder positions and higher power consumption for sub-critical speeds. For super-critical speeds, they lead to lower power consumption, due to lower particle mobility as the particles lock together better.
