Impact Crusher Working Principle

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. 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.

Impact Crusher | Description | Advantages | Types of

Aug 15, 2012· The word impact makes sense that in this particular type of crusher some impaction is being used for crushing of rocks.
