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

Effect of mill type on the size reduction and phase

Effect of mill type on the size reduction and phase transformation of gamma alumina. Shearinduced phase transformation is observed in planetary ball mill. It is more favourable as it promotes grain size refinement and an increase in surface area. A presence of limited shear stresses in the SBM (vibration milling) results in a small
