TECHNICAL NOTES 8 GRINDING R. P. King

The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines fracture of the media
