operation of dry grinding minerals

Dry Grinding VS Wet Grinding Mineral Processing &

The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the

A comparative study on the effects of dry and wet grinding

01/09/2019· Dry grinding produces rougher surfaces (mechanically activated centers) and more agglomerated particles than wet grinding. On the other hand, the greater energy in dry grinding can deform the structure of minerals and mechanically activate their surfaces. These activated centers adsorb passivated ions and generate passive layers on the surfaces or enhance collector adsorption and flotation kinetics, reduce energy consumption during flotation and as results improve flotation separation
