The attritor ball mill, also known as stirred ball mill, is a kind of vertical ball mill. It can be divided into dry type and wet type, suitable for grinding a variety of materials, such as industrial ceramics, fireproof materials, silicate materials, metal powder, ores, etc. It is equipped with an agitation system inside the grinding cylinder.

The Attritor is filled with media and the grids restrain the media while the slurry is allowed to pass through. The principle of circulation series is the high circulation pumping rate which forces the entire contents to pass through the Attritor several times per hour. This results in a faster grind and a narrower particle size distribution.

The attritor, or stirred ball mill, is a grinding mill containing internally agitated media. There are quite a few types of attritors; they can be categorized as dry grind, wet grind, regular speed (to 400 rpm) and high speed (400–1,800 rpm) attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity ...

Attritor fits into the family of mills. For example, ball mills use large media, normally ½" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead and horizontal, use smaller media (from 1/64" to 1/8"), but run at a very high rpm (roughly 800-1200).

Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.
