***2 New Design Primary Impact Crushers : 1.widely used 2.Large proportion of broken ratio 3.powerful impacting force ***2 New Design Primary Impact Crushers Impact Crusher Impact crusher is a new type of broken equipment with high efficiency. Application The PF series impact crusher is applied for primary, secondary and fine crushing. It is widely used to process all kinds of hard materials(like granite, marble, limestone, basalt, etc.) with comprehensive strenth less than **0 Mpa in the industries of roads, mineral, railways, water conservancy project, electricity power, chemical industry, building materials, etc. Working principle This impact crusher machine crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weigh security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine. Primary Impact Crushers Features 1.Simple structure, small size, light weight, large capacity. Therefore, they have low production costs. 2. Ore is broken along the joint surface, so they have less power consumption and high efficiency. 3. Large proportion of broken ratio that can reach *0, so it can simplify the crushing process. It also can make three section broken change into two or one, which can reduce the cost of beneficiation. 4. It has selective fragmentation function, the broken products have uniform particle size, most of which is cube. It is widely used in the bridge construction, high-speed roads, port, airport constructions. 5. High chrome and abrasion resistant blow ber, powerful impacting force and long service life. 6. Zero key connected, easy maintenance and replacement of wearing parts. 7. Diversity installed way, can be equipped on mobile crusher. 8. The internal air circulation of vortex chamber with little dust pollution. Technical specification Model Rotor Size (mm) Feed Opening Size (mm) Max.
