    20191018&ensp·&enspBall 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.

  • Efficiency and grinding media filling level IEEE

    Since delivery time for parts to repair the damaged drive was lengthy, a decision was made to reduce the charge in the ball mill from approximate 32% filling level to a point low enough to allow the mill to be operated with the single remaining drive. Surprisingly the result was a minimal loss in production, with a significant gain in efficiency.
