A numerical tool known as the discrete element method DEM is used to study the motion of the ball charge in ball mills. In particular the motion of individual balls in the ball charge is simulated. An interesting aspect of this simulation is that it yields the frequency distribution of ball collisions as a function of collision energy.

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 18 2001 These two works did not explore the tumbling mill problem in any great detail. Rather they solved the 3D DEM problem for a limited number of bodies in a tumbling mill. Acharya simulated the motion of balls in a 25 28 cm mill and Kano et al. too dealt with a laboratory mill of 15 15 cm size. 2. Modeling of charge motion 2.1. The DEM
