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

Ball Mill The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form he fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 05 to 35
