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.

A whole range of grinding/milling techniques and equipment are available for application with different types of food. Grinding/milling can be carried out dry or wet. In wet grinding/milling smaller particle sizes can be attained. Often dry grinding (milling) is combined with sieving or air classification, this results in particle size fractions.

CRUSHING: Crushing is accomplished by compression of the ore against rigid surfaces or by impact against surfaces in a rigidly constrained motion path. Crushing is the first mechanical stage in the process of comminution. Stages of crushing: Primary crushing → Run-of-mine ore (ROM) reduced to 10-20 cm (4"-8"), ( " = inch = 2.54 cm)

In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to maximum separation.
