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. Often, the ball used in ball mills is oversize “just in case”.

How Coarse can Ball Mill Feed be Grinding

A quick check of the Rowland optimum feed size for this ball mill is between 3 and 4 mm; operating either circuit you describe will be at least 15% inefficient compared a more conventional ball mill feed size. The screen doesn't matter in terms of energy efficiency; only more crushing (or a small rod mill) that will improve the energy efficiency.
