Nov 11, 2013 In this research, a planetary ball mill was chosen as a grinding tool due to its simplicity. The sieved powder was first mixed with Pluronic F127 and milled at different mass concentrations (0.4%, 1.2%, 2.0%, and 2.8% ( w / v )) at a constant milling time (4 h) and fixed bead amount (25 g).

Calculate and Select Ball Mill Ball Size for Optimum Grinding

Aug 02, 2013 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.
