A ball mill can grind and homogenize small sample volumes down to the nano range. The Emax is an entirely new type of ball mill for high energy input. Ball mills are among the most variable and effective tools when it comes to size
2017/03/17 · 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. It is especially difficult to teach mill
