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".
Scope : The Media Charge_Optimal Ball Size spreadsheet was designed to estimate the ideal make-up ball size to any given grinding application, on the basis of the empirical correlations independently proposed by Ettore Azzaroni and Allis Chalmers.
For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding.
Optimum choice of the make-up ball sizes for maximum throughput in tumbling ball mills, For the same amount of ball charge, the number of balls in the mill decreases as the ball size increas Thus, the S values are lower for, For a single size of make-up balls, the ball size distributions exhibit a mono-modal size distribution with a .

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
