Grinding in Ball Mills Modeling and Process Control
The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material (feeders) and the system for discharging the output product. The size of a mill is usually characterized by the • speed of rotation of the mill • slurry density in case of wet grinding operation.

More InfoATTRITOR GRINDING MILLS AND NEW DEVELOPMENTS
Attritors wet grind Attritors regular speed Attritors and high speed Attritors. 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" or larger and run at a low (10-50) rpm.
