Understanding Comminution: Compression versus impact crushing

The term ‘gentle crushing’ may sound somewhat contradictory, but compared with the raw power of impact crushing, compression crushing could be considered a much gentler method which makes it more favourable for harder, abrasive rocks. If impact crushing is opening a walnut with a hammer, compression crushing is the nutcracker method.

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.
