  • Charge behaviour and power consumption in ball mills

    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.

    Analysis Of Power Draw In Ball Mills By The Discrete

    Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a ...
