Grinding in Ball Mills: Modeling and Process Control

the 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.
