PFW Series Impact Crusher (hydraulic)

PFW Series Impact Crusher PFW series impact crusher has three cavity and two cavity two categories devices. It uses integral bearing steel structure, a unique hammer fixing means, adjusting means improved, and comes with an open top devices, making the performance of the device is greatly improved, downtime is short, and can quickly complete replace the hammer and other wearing parts, it has a vital role in the crushing work.

Features

  • Key components of the equipment are made of advanced machining and hot treatment processes. Counterstrike baord is casted by high wear resistant material and the impact face is provided with a lining structure, largely improving the wear resistant property of the impact plate. Board hammer is poured by the process integrating with highchrome material and wear-resistance and thermal impact resistance properties. It makes fullest use of the Hammer bars with symmetric design, which can extend the woring life about two times than the old design.
  • The European Style impact crusher adopts a rigid heavy rotor to gain more rotary inertia and counterforce to increase the crushing capacity; and is tested by the tight test method on the defect on the surface, near surface and inner surface to ensure its high quality and improve the rotor performance.
  • The overall cast steel bearing base is fully matched with the crusher, and largely increase the radial strength of the bearing base and improves anti load resistance capacity; while the split type bearing base is out of these advantages.
  • The flat hammer of PFW impact crusher is fixed on the rotor by a group of wedge blocks. The wedge block tightly locks the flat hammer from horizontal and vertical directions and needs more fastening torque to enable the flat hammer installed in a simple and convenient way and eliminate abrasions from the flat hammer fixed by bolts.
  • When iron or other hard material that cann't be crushed, be fed in the crushing chamber, the front and rear impact shelves will be pushed back, so the hard material will be discharge ,the impact crusher resume production and eliminate the blocking risk.
  • PFW series impact crusher is installed with hydraulic system at both side. This system can be used for opening the cavity and adjusting the discharge port. It makes changing spare part more easy, reduce time and human labour.

Working Principle

PFW Series Impact CrusherThis machine crushers materials with impact force.When the materials enter the blow bar area, they are crushed by the high-speed rotor, then are thrown to the impact plates on the rotor for secondary crushing.Next material reboound to the rotor be crushed again. Thus process continues till the material be discharged. The size and shape of final product can be changed by adjusting the gap between the impact plate shelves and rotor.
