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”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

of the ball - the smallest theoretically possible - can be referred to as critical. For example, on fig 1, for the dotted curve relating to the original feeding of 10-0 mm, the size of the ball D = 9 mm evidently will be critical; having O loaded a mill, which has balls of the critical diameter of 9 mm, from batches

Rod mills, how they function

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
