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 singlechambered), allowing the use of different sizes of grinding media.
This roller press can improve the grinding capacity by 50100% compared to ball mill systems and reduce the power consumption of the grinding system by 3040%, and 2030% that of finished cement. The squeezed materials is easy to grind and fine material accounts for 3030% and material smaller than 20 mm accounts for 6585%.
