• ### Grinding in Ball Mills Modeling and Process Control

The speed of rotation of the mill determines three basic types of operation modes slow rotation (cascading) fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the charge in the mill and a different impact of the milling bodies on the ground material.
