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 ...

Many parameters may influence the outcomes of dry grinding in stirred media mills. It is possible to classify such parameters as the mill's design properties (, impeller types, the features of impeller arms, the length/diameter ratio of the mill, the orientation of the shaft), vertical [68] or horizontal [912]
