### Calculate and Select Ball Mill Ball Size for Optimum

2020-7-22In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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 andor mill liner wear and .

### The operating principle of the ball mill Primo Pizza

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then discharge of ground material performed .
