PFW Impact Crusher

PFW Impact Crusher

PFW series crusher from specially designed to feed the A&C measurement quite large, even can be used as a specific program of two or three stage crushing machine. They may be very suitable for the element of production and medium hard rock for example exploration and quarrying applications in addition to the construction and destruction of materials.Impact crusher is a new type of high efficiency crushing equipment, the characteristics of small volume, simple structure,low energy consumption, large production capacity, uniform product size, and selective crushing effect.

  1. the optimization design of the crushing chamber and heavy rotor structure, make the equipment production increased 20%, more stable operation.
  2. wedge unique assembly locking plate hammer, hammer board and the rotor contact surface after machining, the plate hammer locking is more safe, reliable.
  3. the material of the contact angle is more reasonable, effectively reduce the wear plate hammer, at the same time reversal use, improve the utilization rate of more than 25%.
  4. integral bearing seat, more large specification bearing, the crusher has larger bearing capacity and longer service life.
  5. hydraulic open top device, hydraulic adjusting the discharge device, so that the replacement of wearing parts and equipment operation more simple, quick.
  6. selection of high-quality alloy wear resistant parts, provide a powerful guarantee for the long-term stability of equipment operation.


  1. Bearing utilizes the actual incorporated cast-steel structure, which usually ensures the best complement crusher frame. In the mean time, that significantly raises the radial concentration of bearing chair.
  2. Special repairing equipment associated with setback bar provides greater dependability.
  3. Reformative modifying machine cheaper enough time associated with equipment quit and also overhaul.
  4. Self-own open-top system can easily quickly complete the actual replacing wearing components.
  5. Bigger bearing standards and greater transporting capability.
  6. Rotor investigation assures steadiness and dependability.

Working Principle

When the machine works, under the driving of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the impact of the rotor plate hammer crusher, and then be thrown to counterattack plate device is broken again, from the counterattack lining board play back plate hammer effect region to break, the materials from large to small, the three into the one or two counterattack cavity repeatedly broken, until the materials are crushed to the required size, discharged from the discharge port. Adjust the clearance between the plate and the rotor back can be achieved by changing the material discharging size and material shape purpose.
