Impact Crusher Working Principle
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
