Understanding Comminution: Compression versus impact crushing | Agg-Net
Compared with compression crushing, impact crushing will create more fines within the circuit, which will cause greater wear if processing abrasive material. This is why rocks with lower silica content are more suited to reduction by impact crushers. When compared with cone crushers, impact crushers often have a lower capital cost, but can

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.
