Calculate and Select Ball Mill Ball Size for Optimum Grinding. Based on his work this formula can be derived for ball diameter sizing and selection Dm <= 6 (log dk) d 0.5 where D m = the diameter of the singlesized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm. The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1". Horizontal mills require much smaller media as small as 0.05 mm to 2 mm. To read detailed specs and submit a quote click here for our metallic media or here for our non-metallic media.

### Ball Millan overview ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. 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
