Wilczek: The mill accepts a maximum particle size of about mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 1020 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.

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 ...

Figure shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.

Some investigations demonstrate that stirred mills (compared to ball mills) have better performance when grinding occurs on a micronscale . This improvement is because the mechanism of supplying energy during stirred milling is different from what happens in ball mills. In ball mills, the abrasive and impact stress lead to particle breakage.
