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).
