Ball Mill - an overview | ScienceDirect Topics

For ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity. This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy. In practice, the ball mill is run at just below this speed (70–80%).

Calculate and Select Ball Mill Ball Size for Optimum Grinding

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.
