Generally, a maximum allowed ball size is situated in the range from D /18 to D /24. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume.
If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and milling by avoiding local impact between the balls. There should be atleast 25% empty place in the ...

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 …
