Calculate and Select Ball Mill Ball Size for …

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 liner wear and ...

Design Method of Ball Mill by Sumitomo Chemical Co., Ltd ...

To predict ball mill grinding behavior using the dis-crete element method, we must first be able to repro-duce the balls' motion in the ball mill using simula-tions. Kano et al.8) have made it clear that it is possible to reproduce the ball motion when the solid material is also present in a tumbling ball mill without fins by pro- viding a suitable coefficient of friction for the balls and ...

The cement mill

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with ...
