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 (4001,800 rpm) attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity ...

A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
