8.3.2.2 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.

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.

where w is the specific grinding energy (kwh/t), w i is the bond ball mill work index (kwh/t), f80 is the feed 80 pct passing size (μm), and p80 is the product 80 pct passing size (μm). it can be seen that in the regime in which the bond equation is valid, energy use increases exponentially as product size decreases with constant feed size .
