    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 sizemills including a roller press are mostly single-chambered) allowing the use of different sizes of grinding media.

  • Charge behaviour and power consumption in ball mills

    The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.
