HSA Series. The HSA High Speed Attritor is generally used in a continuous mode. The material is charged into the mill at the top and is discharged out the bottom side, making use of centrifugal force. The HSA is used when smaller particle size (generally 40 mesh) materials are fed into the machine and micron size end product is desired.

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 ...
