  • Grinding Mills - an overview ScienceDirect Topics

    According to the ways by which motion is imparted to the charge, grinding mills are generally classified into two types: tumbling mills and stirred mills. In tumbling mills, the mill shell is rotated and motion is imparted to the charge via the mill shell. The grinding medium may be steel rods, balls, or rock itself. Media ball sizes, for ...
