Charge behaviour and power consumption in ball mills ...

Aug 01, 2001  For a typical 7-m-long mill, the power required is therefore predicted to be 2.1 MW. This is consistent with a peak motor power rating of 3.3 MW that would commonly be used for a mill of this size. Field data is very difficult to obtain for comparison with the DEM results so we instead compare with some of laboratory observations.
