Calculate and Select Ball Mill Ball Size for Optimum Grinding

2013-8-2  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

Correlating common breakage modes with impact

2020-11-1  Narrow size fractions of a Portland cement clinker and a chromite sample were used as the experimental materials. The size fractions of both samples coarser than 3.35 mm were used in the single-particle impact loading tests. Ball mill grinding tests were performed with the narrow size fractions of the clinker sample finer than 2.36 mm. 2.2.
