The Attritor is a grinding mill containing internally agitated media. It has been generically referred to as a "stirred ball mill." A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2"

The attritor mill contains a built-in data acquisition unit by Baldor. It was used to measure the torque and rotation speed as a function of milling time (Santhanam and Dreizin, 2012, Santhanam and Dreizin, 2013). The mechanical power required to turn the impeller was calculated from the product of torque and the rotation speed.
