Impact crusher is also called stone impact crusher which is widely used in rock mining and quarrying and stone crushing. It is often seen in quarrying plant, ore beneficiation plant and power station and it is an important impact crushing machine. We have the most advanced impact crusher, and thousands of Hongji PF series impact crusher has been sold to all over the world since Hongji Group built in 1960. As a kind of crushing machinery, China impact crusher is an ideal equipment and it is widely used for the coarse, medium, fine crushing of materials with a size less than 500mm and a compressive strength no more than 350MPa such as the granite, limestone, concrete and so on. Stone impact crusher has a good application in the mining, railway, high-way construction, water conservancy, cement, chemical, construction and other industries.

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 Structure Features of Impact Crusher

1. Adoption of advanced manufacturing processes and selection of high-end raw materials.

2. Heavy type rotor design and strict testing method to guarantee high quality rotor.

3. Adoption of the Integral cast steel structure on bearing seat makes it matches well with the crushing frame and increases the radial strength of it, while the divided design does not has this advantage.
