Solids | Choose the Right Grinding Mill | Chemical Processing

Attrition mills can operate in either batch or continuous mode and suit harder-to-grind material such as metal powders, metal carbides and glass frits. Their shaft speed runs from 75–500 rpm and media generally range in size from 5–13 mm. Feed material can be as coarse as 1/2 in., while end product size can be as fine as 2–3 microns if the mill operates in a batch mode.

Cryogenic Attrition Mills - Union Process

Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits. Attritors can generally grind to finer size particle size range than impact or hammer mills by combining the advantages of cryogenic temperatures with both impact and shear forces inherent to high energy internally …

Attrition Mills | PDF | Mill (Grinding) | Materials Science

Attrition mills use the hammermill principle to a certain extent; i.e., shattering by/impact. However, they also impart a shearing and cutting action. Grinding is done between two discs equipped with replaceable wearing surfaces. One or both of these discs is rotated; if both, they rotate in opposite directions.
