Based on Discrete Element Method(DEM), movements of steel balls in ball mill were simulated by Particle Flow Code in three Dimensions (PFC 3D), the motion states of all steel balls and balls with one diameter were discussed respectively at different ball filling rate. The results indicated that steel balls moved from cascading motion gradually to throwing motion with the increasing of rotary ...

The results of discrete element method simulation were compared with actual grinding experimental results. The grinding rate constant K can be expressed as K=a exp(bn), where n is the rotation speed. To investigate the correlation between K and the simulation results, a new factor, the calculated force, was defined as F cal =average force acting on a ball coordination number.
