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.
