The PF Impact Crusher

The Introduction to Impact Crusher: The china impact crusher is a new type of highly efficient crushing machine, with the characteristics of small size, simple structure, high crushing ratio (reaching 40), low energy consumption, strong production ability and well distribution of particles, and a more significant function of crushing selectively makes it a very promising crushing machine. It has been applied in some ore dressing plants owing to the appearance of highly-abrasive materials.

The PF Impact Crusher involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.It Usually acting in the secondary or three-stage crushing equipment, Impact crusher is the ideal crusher for aggregates processing in high-type high-type highway building, water conservancy and power construction. For crushing materials whose compressive strength is under 360Mpa, and particle size is under 500mm, impact crusher with end products in cubic shape is better than cone crusher and hammer crusher.

Structure of Impact Crusher: The impact crusher is mainly made up of rotor rack, impact rack, ratchet wheel cover-open device, rotating parts as well as other components. There are two parallel rotors in the mobile impact crusher, with some altitude differences. The position of the first rotor is relatively high, with an angle of 12° from the ligature of the first and the second rotor. The first rotor is a heavy type, used for coarse crushing; the second rotor rotates fast, which can meet the need of the final products. The rotors are both fixed with bolts. The 12 blow bars distributed to 6 rows are made of high manganese steel. The rotors are fixed on the main shaft, separately connected with the coupling of two engines. All impact boards are made of high manganese steel.
