Moreover, optimizing ball filling ratio and mill speed appropriately by the AR method, the residence time of feed in the grinding chamber could be reduced and the mass fraction of the desired size was improved during the grinding process [14,15]. More recently, Chimwani et al. [16] investigated the influence of feed size on ball grinding.
