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

A comparative study on the effects of dry and wet grinding ...

Dry grinding has significantly lower media and liner wear than wet grinding; thus, the Fe concentration in the pulp of downstream process for the same mineral is relatively lower after dry grinding. Dry grinding produces rougher surfaces (mechanically activated centers) and more agglomerated particles than wet grinding.
