Performance
1.PFW Impact Crusher applies top-level technologies and materials. The heavy-duty rotor design and strict inspection guarantees high quality. Meanwhile, the unique fixed device makes the hammer more reliable.
2.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.
3.The unique fixing device for hammers,make it more reliable.
4.PFW Impact Crusher can equip the hydraulic control system, through which the discharging granularity can be adjusted quickly. Besides, it's helpful for quick replacement of spare parts.
5.Self-equipped open-top device can quickly complete the replacement of wearing parts such as the hammer.
6.Selection of the bearing with larger size and higher load.
7.Finite element analysis on the rotor to ensure its performance more stable and reliable.
Working Principle
PFW Impact Crusher is a kind of crusher which crush the raw material by using impact energy. When enter the zone of the board hammer, the raw material is crushed by the high-speed impact of it. And then the raw material is threw up to the impact device installed on the rotor and is crushed again. Then the raw material is crushed for another time when it is rebounded from impact liner to the zone of board hammer. The process repeats until the raw material is crushed into the desired size and discharges from the bottom of the machine. The final product size and shape can be changed by adjusting the gap between impact frame and rotor frame. PFW Impact Crusher adopts spring safety device behind the impact liner. When the non-crushed items enter the crusher chamber, the impact frame front and back will be draw back and the non-crushed items will be discharged from machine.
