I.Impact CrusherUsage and Application This impact crusher is used for primary, secondary, fine crushing mining and rocks (for example, the granite, marble, and limestone) materials with compressive strength less than 350 MPa. It is widely used for sand and rock producing in the industry of roads, railways, water conservancy projects, electricity power, building materials and so on. II. Impact Crusher Working Principle The materials are crushed by impact energy produced in the crusher. When the materials enter the zone of the blow bar, they are flung into the impact equipments via the high-speed impact of the blow bar. These materials will be re-crushed after rebounding into the impact plate. The process goes on until the materials are crushed to the required size and then will be discharged from outlet of machine. III. Impact Crusher Features 1. Cubic shaped end products; 2. Adjustable end products sizes, simple crushing process; 3. High chrome and abrasion resistant blow bar, powerful impacting force; 4. Non-key connected, easy maintenance, economical and reliable; 5. Compact construction, high efficiency. IV. Impact Crusher Main Specifications ItemModelRotorSize(mm) FeedOpeningSize(mm)Max.
