Crushed aggregate may be combined with other materials to produce concrete. After being processed in the impact crusher, the aggregate is screened for sizing. This process might be handled in a screen shaker or during the washing process in an aggregate washer. If the aggregate is sufficiently crushed, it is transported to the storage area.
