Modeling and Optimization of a Vertical Shaft Impactor for

Vertical Shaft Impact crushers have been used for a long time to reduce the size of particles and to give particles a cubical shape profile. Very few investigations have been performed on the inner workings of the VSI crusher and even fewer attempts have been made to model the particle breakage and collisions that occur inside it.

Impact Crusher Working Principle

Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).
