PF Series Impact Crusher






Wear-resistant Plate Hammer

The plate hammer of PF impact crusher is made from high chrome material and wear-resistant material through composite process, and undergoes strict heat treatment, so that the impact crusher possesses good mechanical shock resistance and thermal shock resistance.

Semi-automatic Safety Design

PF impact crusher is equipped with self-weight safety device on the rear upper rack. After the non-crushing material (e.g. iron block) enters into the crushing cavity, the front and rear impact racks will move back, and the non-crushing material will be discharged from the crushing machine. When the impact crusher resumes working, the impact racks will return to their normal working positions with the help of self-weight safety device, thus avoiding the risks generated due to equipment overload and the losses caused by shutdown and maintenance.

Size of Discharged Material is Adjustable

For different market requirements at different stages, SBM set a mechanical adjustment device on the top of PF impact crusher, and the user can adjust the spacing between the impact rack and rotor through twisting the bolt of this device, so as to realize the adjustment of size of the discharged material.

Ratchet Wheel Flapping Device

PF impact crusher is equipped with two identical sets of ratchet wheel flapping devices on both sides of the rack, which is composed of high-strength left and right spiral trapezoidal screw and ratchet wheel reversing mechanism. When the impact crusher needs be stopped for parts replacement and other maintenance and service operations, the user can easily and stably open and close the rear upper cover of the impact crusher through this device for service operations.
