Impact crusher structure, working principle and features
1.1 Impact crushers can be divided into two types according to the number of rotors: single-rotor and double-rotor impact crushers. 1.2 The structure of the single rotor impact crusher (Figure 1) is relatively simple and consists mainly of the rotor 5 (strike plate 4), the impact plate 7 and the machine body. The rotor is fixed to the main shaft.

Impact Crusher Working Principle
Impact crushing crushing grinding method. Shear crushing is accomplished by breaking along or across lines of cleavage. It is possible, when required, for a crusher to use a combination of two or three of these principles. The selection or sizing of a crusher is much helped by measuring the rock's hardness during engineering.

Crushing plants
A jaw crusher is great for breaking down very large pieces of rock into smaller more manageable sizes. These smaller chunks can then be fed into an impact crusher. These work by metal rotors smashing the material against the inside an impact chamber. Creating a much smaller material that is a similar shape and size.
