Jaw Crusher - an overview | ScienceDirect Topics

Hammer (impact) crusher: The feed is fragmented by kinetic energy introduced by a rotating mass (the rotor) which projects the material against a fixed surface causing it to shatter causing further particle size reduction. This crusher produces more rounded shape.

Buyer's Guide: Crushers - Equipment & Contracting

An impact crusher can have a horizontal shaft or a vertical axis. This type of crusher may not be as effective for producing smaller pieces. The force needed to break down the material depends, in part, on the energy generated by the broken pieces. The smaller the piece the less energy its impact against the hammer produces.

Impact generates stress waves that propagate strain energy away from the region of impact. If the energy transformed into elas-tic vibrations amounts to a large fraction of the total energy, the rigid-body dynamics model is not applicable any more, and the approach based on wave propagation (or the transient model) is more suitable.

Impact Crusher Working Principle

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 could be described as material dropping
