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
ball mill for aggregate grinding process Exodus Heavy. ball mill for aggregate grinding process,When the speed of the ball mill is certain the filling rate is large the steel ball hits the material more times the grinding area is large the grinding effect is strong but the power consumption is also large and the filling rate is too high it is easy to change the movement state of the steel ball
