Crushing Theory • The amount of power required for crushing is a major consideration in selecting crushing equipment. • The greatest problems lies is the fact that most of the energy input to a crushing and grinding is absorbed by the machine itself, and only a small fraction of the total energy is available for breaking the material.

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".

process occurs in two steps: breaking the hard structure of the cane and grinding the cane. Breaking the cane uses revolving knives, shredders, crushers, or a combination of these processes. For the grinding, or milling, of the crushed cane, multiple sets of three-roller mills are most commonly used although some mills consist of
Grinding raw materials needs lots of energy. Tube mills had been used for grinding, but the energy efficiency level was lower. Therefore, the introduction of highly efficient grinding equipment was anticipated. Descriptions The vertical roller mill has high energy efficiency and the installation space is smaller compared with tube mills.
hammers and screen bars, it is practical for crushing the less abrasive materials such as pure limestone and coal. Attrition crushing is most useful in the following circumstances: • when material is friable or not too abrasive • when a closed-circuit system is not desirable to control top size Shear Shear consists of a trimming or cleaving
