22-06-2015 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). Dynamic impact

MoreImpact. Impact crushing reduces material by utilizing the theory of mass versus velocity in two ways. In one method, material can be broken by its collision with hammers that are fixed to a spinning rotor. The material is broken mainly by its initial impact with the hammer and then further reduced by its impact against the breaker plates.

MoreThe theory in can be significantly simplified for impact of a semi-brittle ice crystal. In this case the plastic region, characterized by intensive particle deformation, is rather thin. This thin plastic layer separates the rear part of the particle, where the deformation is small, from the thin region near the rigid wall of a compressed crushed crystal material.
