Get PriceThe sizing ofball millsandballmilling circuits from laboratorygrindingtests 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...
