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.
Effect of ball size and powder loading on the milling
The particle size reduction results from the complicated dynamic interaction of the balls with turbulent slurry during the ball mill process, imposing a difficulty in quantitative interpretation of the observed phenomena of: (1) the existence of the optimized ball size at a given rotation speed; and (2) the decreased optimum ball size with increased rotation speed (rpm).
