China Granite Crusher Machine Pfw1214 Impact Crusher for Sale

Brief introduction of PFW impact crusher
The PFW series Euro-style impact crushers are new high-efficiency hydraulic control impact crushers developed on the basis of international advanced technology for impact crushers, mainly to ease maintenance operation of impact crushers, improve the service life of wearing parts and the equipment performance, also reduce the processing cost for crushing materials. And it has innovatively designed the rotors and impact frames, introduced a hydraulic system for adjustment control and top opening operation, and simultaneously developed coarse and intermediate crushing models according to users' demands to satisfy different job requirements.
Working principle of PFW series impact crusher
When the pfw impact crusher for sale works, the motor drives the rotor rotate with high speed,on the rotor where installed the hammers. When the materials are feeded in to the machine,they are crushed due to the high speed impact of the hammer and then are thrown to the impact plates on the secondary rotor for secondary crush. Then the materials will be shot back to the hammers again for the third crush. This process repeats until the materials are crushed into the required size and discharged from ourlet.
Applications of PFW series impact crusher
PFW impact crusher, construction impact crusher machine is mostly used as secondary crusher and it well fits for crushing numerous medium and soft mineral &rock materials, such as limestone, feldspar, calcite, talc, barite, clay, tombar thite, kaolin, gypsum, and graphite, construction waste etc...

Features of PFW series impact crusher
1. Adoption of the world-class manufacturing processes and selection of the most high-end raw materials.
2. Design of heavy type rotor and strict testing method to guarantee high quality rotor.
3. Adoption of the integral cast steel structure on bearing seat makes it match well with the crushing frame and increase the radial strength of if, while divided design does not have this advantage.
4. The unique fixing device for hammers makes it more reliable.
5. The improvement of the adjusting device makes the maintenance easier.
6. Self-equipped open-top device can quickly complete replacement of wearing parts, such as hammer.
7. Selection of the bearing with larger size and higher load.
8. Finite element analysis on the rotor ensures its performance more stable and reliable.
