A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.

Alamprese et al.  investigated the optimization of working conditions of a ball mill used for chocolate refining process in order to reduce refining time and energy consumption without loss of quality characteristics of the final product.

2012710&ensp·&enspthe milling process takes place during rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product. The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product.
