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"
