Analysis of grinding kinetics in a laboratory ball mill using …

 · In addition to the ball mill, simulation of various milling equipment such as centrifugal mill , stirred mill and planetary mill were also studied. For example, Mori et al. studied the correlation between impact energy and grinding rate for a wet ball mill and reported that the grinding rate can be predicted through the measured impact energy using DEM.
