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.

Crush vs Impact - What's the difference? WikiDiff

In lang=en terms the difference between crush and impact is that crush is to be or become broken down or in, or pressed into a smaller compass, by external weight or force while impact is to collide or strike.

Jan 01, 2012  2.2. Quasi-static compression and low velocity impact tests. We carried out uniaxial compression testing using a screw-driven machine (INSTRON 5569) following ASTM C365/C 364 M-05.The compression tests were carried out in the quasi-static displacement-controlled regime with a nominal displacement rate of 0.5 mm/min. Samples with 3 × 3 = 9 unit cells were used as shown

DESIGN AND ANALYSIS OF A HORIZONTAL SHAFT IMPACT

In an impact crusher the breakage takes place in a lesser time span as compared to the conical or jaw crushers. So here the nature and magnitude of forces as well as the energy dissipated due to impact breakage is different from that of the relative slow breaking that occurs due to compression or shear in other type of crushers.
