Answer to Question #226946 in Chemical Engineering for Lokika

Question

What is the difference between dry grinding & wet grinding?

Answer 1

Dry grinding generally involves dispersing the material in a liquid and using solid grinding media to decrease the size. In contrast, wet grinding involves dispersing the material in a liquid and using solid grinding media to reduce size.

When opposed to wet grinding, dry grinding uses more energy. It generates a broader range of particle sizes. Dry grinding causes more surface roughness, particle agglomeration, and surface oxidation than wet grinding, all of which impact the flotation process.
