(Ball mill) To improve the ball mill grinding efficiency, you must first understand the factors that,Cement mill - Wikipedia,Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.
