Before the introduction of thirdgeneration grinding mills for wet fine and ultrafine grinding, tumbling mills were used. The number of revolutions controls the power consumption for the grinding of media. Hence, it has a moderately smaller power density. However, for ultrafine grinding, the time required for grinding is considerably longer.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...
