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 .
Apr 01, 1999 the calculated power draft is maximum at about 50% ball load.1, mill power is a function of ball mass (m b) and the distance between mill center and the center of gravity of ball mass (r g).So, as the mill filling increases m b goes up, but r g decreases.Therefore, the power draft passes through a maximum.
