Ball Mill Ball Size Calculation. Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill Coghill and DeVaney 1937 defined the ball size as a function of the top size of the feed i.e. d V 0.40 K F dB ball size cm F feed size. Read More

the ball mills. It was expected a loss on mills performance as predicted by grinding tests showed on Figure 8. Figure 8 - Comparison to standard charge and balls scraps. Thankfully the performance of the vertical mill was still better than the ball mills which reinforces the use of this technology.

Jun 01 2009 The reason regrind ball mill operation has a higher indirect energy than the IsaMill operation is that it carries a penalty for using steel as grinding media. Overall there was almost a 15 decrease in the direct energy consumption when the IsaMill was substituted for the regrind ball mill.
