Cement mill - WikipediaBall 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. |
