Bond proposes an optimum reduction ratio for rod mills [BON 61b, p. 545]. If the real ratio deviates, then W i must be multiplied by a correction coefficient (equation 26 in [BON 61b, p. 545]). For a ball mill, if the reduction ratio becomes less than 3 (target grinding of concentrates), the energy index W i must be multiplied by a given .

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.
