As was mentioned above a gearless mill drive constitutes both an important part but also one of the most critical elements of a concentrator or a cement plant Their purpose is to ensure the continuous rotation of specific types of tumbling mills more specifically autogenous grinding AG mills semi-autogenous grinding SAG mills or ball...

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...
