Crush for Cubical Aggregate
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. 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.

Production and Uses of Crushed Rock Aggregates: An …
In general, aggregates should be hard and tough enough to resist crushing, degradation and disintegration from any associated activities. About 52% of all construction aggregate is crushed stone, while 48% of the remaining is sand and gravel (AASHTO, 2001). A mineral aggregate is used to denote a rock product as aggregate.
