Ball Mill Power Calculation Example#1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of80% passing ¼ inch(6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).
Get a QuoteThe sizing ofball 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...
