• 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 The Milling ProcessDefinitions Cutting speed v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters
