Crushed Aggregate | LaPrairie Group
Crusher chip is a crushed aggregate, also known as rock aggregate, produced by crushing larger stones in an impact crusher. This type of crushed aggregate has a finer texture than that produced by other types of crushers. The stone aggregate is first broken up in a hammer mill or quarry crusher. Next, the stones are reduced to smaller pieces

Impact Of Silica In Aggregate Crushing
Impact Of Silica In Aggregate Crushing. Stone Crushing Machine: Impact of silica in aggregate crushing
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.
