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.

Optimization Of Mill Performance By Using. As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. the risk of underloading or overloading the mill is an additional factor. a direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is.
220.127.116.11 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
