Modelling and simulation of particle breakage in impact crushers

The control variables in the developed model are the belt conveyor feed rate, the material feed rate into the VSI crusher rotor, the bi-flow or cascade feed rate and the rotor tip speed of the crusher. These four control variables are optimally coordinated in order to improve the operation energy efficiency of the VSI crushing process.

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.
