Choose right speed to improve ball mill grinding ...
1. If the rotating speed is low, the ball in the ball mill will be lifted to a small height. The ball will slide down from the top of the ball load by the gravity of the ball itself. At this time, the impact force of the ball is very small, but the grinding effect is strong. The ore is mainly peeled and crushed, and the grinding effect is not high.
Calculate and Select Ball Mill Ball Size for Optimum Grinding
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.
