A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level toCalculate 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 andOrway Mineral Consultants Canada Ltd. Mississauga, ON,Over the years, it has been determined that Efficiency Factors (EF1 to EF9) should be applied to Equation 1 to drive the corrected power requirement (Rowland, 1982). The equation for Third Theory of Comminution Bond’s was originally developed for use with conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill).

If the rod mill feed is produced by open circuit crushing, use a factor of 1.2 for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less (e.g. from a closed circuit crusher) do not apply a rod mill efficiency factor.
