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 Mills. are special designs of agitator bead mills and are among the slow-running mills with circumferential speeds of approx. 0.5 m/s -2 m/s.

The Dry Grinding Process. The Attritor dry grinding process is achieved in a stationary tank by means of a rotating shaft and arms that agitate the media into a random state of motion of internal porosity called kinematic porosity. In this expanded condition, the media and particles are free to move, collide and impinge upon each other.
