Introduction to the PFW Impact Crusher
China mining equipment Co.,Ltd. is the world leading manufacturer in the ore and mineral processing equipment .And now you can find thousands of crushing equipment like the PFW Impact Crusher all over the world since its founding day,which also have become the most popular crusher in the world .As we all know,rotor is the central heart of compact crusher and also the most strict inspection spare parts,which has played a key point in the work process.So our company have devoted plenties of labour and resources to the research and invention. And the heavy rotors with robust structure has received more bigger rolling inertia.With adoption of the high abrasion-resistance materials and the best quality crushing cavity ,the performance has been fully showed out.
Working Principle of PFW Impact Crusher
This machine uses the impact energy to crush the materials and it can change the granularity and size by adjusting the spare between the impact and rotor frame .and this machine adopts the spring secure equipment installed behind the impact plate. And when the non-crushing materials enter the crushing cavity ,the front and back impact plate will retreat and then be discharged .As it enters the hammer areas ,the materials will be crushed as the high-speed impact from the hammer.And at the same time,they will be thrown into the impact equipment installed on the rotors,and then the secondary crush will begin.After the secondary crushing,the materials will rebound to the hammer areas from the Impact Plate to be recrushed .This process will be circled ,until the materials reanch the specific sized .The final products will be discharged from the discharging opening .
Highlight:some non-crushed materials should not enter the machine to avoid the huge damage to the equipment.
Application of PFW Impact Crusher
PFW Impact Crusher is suitable for the soft ,mid and hardness rocks and widely applied to the field of mining,metallurgy,fireproof materials ,and chemistry .And it can also be used in the highway ,construction stone crushing, water conservancy project and other areas.
technical features of PFW Impact Crusher
1) World advanced manufacture crafts and most top manufacture materials.
2) Heavy rotors design, strict inspection manners and high quality rotors .
3) Bear seat adopts the whole style cast steel structure，which can ensure the perfect coordination between the bearing seat and crusher and meantime have greatly improved the diameter tensile strength . However ,the split bearing seat should not have such these features.
4) Unique hammer fixed equipment ensure the better reliability.
5) Improved set adjustment reduce the inspection and halt time.
6) The uncap equipment can quickly complete the change of the hammer .
7) Larger bear specification ensures the high bear capability.
8) The analysis of the rotor ensures the stablility and reliability.
main structures of PFW Impact Crusher
PFW Impact Crusher are mainly including rotors ,compact rack,frame,hydraulic uncap equipment ,counter and other spare components.
Structural characteristics of PFW Impact Crusher
1) Advanced manufacturing materials ;world-class crafts.
2) The rotor adopts the heavy dsign and the serious testing way.
3) Unique fixed way of the hammer.
4) The size of the bearing is bigger and so it is the bearing capacity.
5) The bearing seat adopts the integrative cast steel structure ,which can greatly strengthen its radial strength.
