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.
It is assumed that the ore is continuously discharged from the feeding port to the discharge port. The ball milling time calculated under this ideal state is the minimum grinding time. The filling rate of the ball mill is 40%. If the slurry level reaches 50% filling rate, the slurry will flow out automatically.
