Analysis of Grinding Rate Constant on a Stirred Ball Mill

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.
