High frequency mining machinery supply by Tarzan 

Introduction:

PF series impact crusher is the new developed impact crusher in our company. We work together with advanced domestic/ foreign R&D department after researching the gravel industry and mining conditions in China. It adopts the latest manufacturing techniques and unique structural design. The finished products are cubes, which are nice granular shape and without tension crack. This kind of crusher can be used as the class II crushing plant or fine crushing plant for gravel production line. 
PF impact crusher is mainly made of chassis, rotor, impact rack and motor, etc. The rotor has a greater rotational inertia with low power consumption. It uses high chrome blow bar (Mn13, Cr2) which is shock resistance and wear resistance. By this way it extends the using life of wearing parts effectively.   
PF impact crusher is the ordinary impact crusher. At this moment, our company had manufactured a kind of PFW Euro impact rusher, which is much easier to operate and better performance.

Application:

It is widely used in metallurgy, mining, cement, chemical industry, refractory, ceramics, highway, water conservancy project, building stone, and mechanism of sanding processing and so on.

Features:
1. Designed according to the standard of highway/railway material using, nice shape, the content of flakiness<12%

2. The discharge port of impact crusher is large, the crushing cavity is high, and it is much more widely used for materials. Finished products are cubes without tension crack, nice granular shape, can comply with kinds of gravels’ grade standard.

3. Simple structure, easy maintenance

4.  Equipped with hydraulic opening device, easy to replace the blow bar.

Principles:

The impact crusher 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 material will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed, then discharge from the discharge port. By adjusting the gap between the impact rack and rotor rack, we can change the finished material size and their shape.
