Impact Crusher an overview ScienceDirect Topics

A jaw crusher crushes only a small proportion of the original aggregate particles but an impact crusher crushes mortar and aggregate particles alike, and thus may generate twice the amount of fines for the same maximum size of particle (O'Mahony, 1990).

Modelling and simulation of particle breakage in impact

Dec 10, 2004· As in the case of horizontal shaft crushers, particle–particle and particle–wall collisions are accounted for through the parameters s and β in Eq. (6) . It is interesting to note that for the same rotor radius, the impact energy per unit mass for horizontal shaft crushers (9) is lower than that for vertical shaft crushers (12) .
