The sizingof ball millsandballmilling 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. It is especially difficult to teachmill...

Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.

Aug 18, 2019· While the quality of steel balls determine the capacity of ball mill grinder. The quality of the steel ball is calculated according to the amount of ore processed per ton (ie 0.8kg per ton of ore). The average steel ball needs to process one ton of ore (1kg-1.2kg). In general, the ratio of ball mill ball is a complicated technical problem.
