The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill .Grinding in Ball Mills: Modeling and Process Control52 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.
