Size Reduction of Solids Crushing and Grinding

The unit operation of the size reduction or comminution of solids by crushers and mills is a very important industrial operation involving many aspects of powder technology. It is estimated that mechanical size reduction of rocks, ores, coals, cement, plastics, grains, etc. involves at least a billion tons of material per year in the United States alone.Get price

Why Do We Need Comminution In Mineral Processing?

Crushing is the first operation of size reduction, while grinding comes after. Some processes, such as froth flotation and leaching processes, require a maximum particle area because maximizing the surface of solid in contact with the liquid or gas phase around enhances reaction, dissolution, catalytic effects, etc.Get price
