A comparative study on the effects of dry and wet

2019-9-1  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.
