Fine Crushing In Ball Mills

  • Cement mill

    Cement mill

    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. Large balls are used at the inlet, to crush clinker ...
