Based on his work this formula can be derived for ball diameter sizing and selection Dm 6 log dk d05 where D m the diameter of the singlesized balls in mmd the diameter of the largest chunks of ore in the mill feed in mm

Early in the twentieth century ball mill manufacturers and other research laboratories developed proprietary batchgrinding tests to measure the resistance of metallic mineral ores industrial mineral ores cement raw materials cement clinkers and related materials being ground to fine sizes in rod and ball mills

B Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the Total Charge Filling Level to be higher than the Ball Filling Level Grate Discharge mills will not face this issue C This value represents the Volumetric Fractional Filling of the Voids in between the balls by the retained slurry in the mill charge As defined this value should never

and with the decreased grain size the necessary ball size also decreases Olejnik 2010 2011 For each grain size there is an optimal ball size Trumic et al 2007 The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding In both

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent

A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semiself locking taper One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill
