3 Principles of Choosing the Crushing and Grinding Process ...

The main purpose of crushing and grinding operation is not to reduce mineral particle size, but to dissociate useful minerals from gangue minerals. Therefore, the ultimate goal of grinding operation is to obtain the highest degree of monomer dissociation with the minimum energy input. Selective grinding has been widely used in the production of ...

Primary Crushing SpringerLink

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below “Dry” crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called “grinding”.

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
