Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy. I think at
Ball mills Ball mills are used for dry and wet grinding of different materials such as cement materials, cement, lime, and ceramic materials. PSP Engineering has continuously reﬁ ned the design of its ball mills. Horizontal ball mills have become a reliable part of grinding plants Main characteristics of ball mills seated on shoetype bearings
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1. 4

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.
