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.
