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.

Influence on mill retention and void filling. There is an optimum powder filling level in the mill, relative to the media volume to ensure maximum grinding efficiency. This occurs when material fills approximately 85% of the media voids. However, mill operation at high circulating loads often results in a void filling somewhat above this amount.
