Attrition mills mechanically reduce solid particles through the intense acceleration of particles against one another in a curved or flat grooved surface called a stator. These mills use a high-speed rotor to create centrifugal forces that facilitate the necessary particle interactions. Rotors' designs can vary, where some include m…

Media sizes for coarse grinding in heavy-duty ball mills range from about 80 mm maximum to 20 mm and for medium to fine grinding mill on down at about a minimum of 8 mm. Below about 16 mm, removal of the ground mixture becomes increasingly difficult and the practical media size limit is around 12 mm.
