Crushing in an impact crusher takes place when the stone is struck by the spinning impact bars, and by that stone being flung against an apron stone. When impact crushing is used, the striking of the aggregate by the spinning rotor’s blow bars knocks off or breaks the elongated fractures. This process is repeated by an impactor in the secondary stage high end calcium carbonate jaw crusher.

Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV, than Irregular or rounded aggregates.If we cut a core out of the same agg (Say in the quarry) and test for compressive strength, will give a higher MPa value. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate
