PFY impact crusher is the newest generation of impact crushers developed by our factory by absorbing advanced technology at home and abroad and according to actual working conditions in domestic sand industry. Such equipment enjoy advantages such as big crushing ratio, the shape of cubic particles of materials after crushing, and long service life of wear-resistant parts. Users of it gain considerable economic benefits. 
After the materials enter the machine, they bump against the rapidly rotating hammer. As a result, bulk materials are broken into pieces immediately. Then the broken materials fly to the striking plate for the second collision and crushing. The rebounded materials collide with the later-coming materials to realize utter crushing.
