There are three ways for grinding media to pulverize materials: 1. Rolling: the grinding media rolls in the grinding chamber and pulverizes the material by selfweight. 2. Impact: with the rotation of the ball mill cylinder, grinding media falls from the high place in the grinding chamber and strikes the material. 3.

Also, each ball mill can process only one order at a given time. Ball mills are either continuous or discontinuous. In this study, only continuous ball mills are considered. In a continuous ball mill as opposed to a discontinuous one, loading and unloading occur during the slurry processing with no need of switching it off (Tang et al., 2018).
