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 could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller.

Impact Crushersproduce the most uniform cubical shape for finished products,due to its consistent ability to uniformly break apart aggregates through striking. Striking can be done with rapid moving hammers as seen on the Horizontal Shaft Impactor or being thrown against an anvil or rock wall as seen on the Vertical Shaft Impactor.

Impact. Impact crushingreduces 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.
