It has been established that a reduction in primary crystal size leads to an increase in crystal lattice deformation. In particular, uniform lattice distortion (for example elongation over axis a) in αAl 2 O 3 is observed in the attrition process. In addition some of the most economic and widespread grinding units are drum ball mills.

The Attritor is a grinding mill containing internally agitated media. It has been generically referred to as a "stirred ball mill." There are quite a few types of Attritors; we can categorize them as dry grind Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors.

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 ...
