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 impact breaker can handle materials with side length between 100 to 500 mm. Its highest compressive strength can reach 350 MPa.  As for mineral impact crusher, there are so many manufacturers in the world, so it's difficult to choose the excellent manufacturer. In China, Henan Hongxing Mining Machinery Co., Ltd possesses good fame at home and abroad, and the impact crusher enjoys high popularity among the customers. We believe that Hongxing Machinery will be your nice choice.

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.

Working Principle of Impact Crusher:

The materials fall to the high-speed rotating turn plate. With the effect of high-speed centrifugal force, these materials will impact with other particles distributed around the turn plate. After inter-impacting, these materials will impact, abrade and crush between the turn plate and the enclosure continuously, and then discharged from the bottom. The impacting, abrading and crushing process will form a closed cycle, with the screening equipment controlling the particle sizes for need.

Installation of Impact Crusher:

The components should be installed according to the scope of application of the machine, and at the same time it should be ensured to have enough space for repairing.

1. The rotors have been debugged before being delivered from the factory, which means no experience is needed. When changing the hammerhead and the rotors, operators should make the balance.
2. Adjusting equilibrium should be made when installing the main machine. The aclinic error of main axis should be less than 1mm/m to adjust the belt and fix the electromotor.
3. Check the installing position of all components. Make sure all the bolts are fixed and check the sealing.
4. Check the electrical wares box. Adjust the delay relay and the overload protectors.
5. Check the reliability of the hydraulic system. Make sure there is no phenomenon of seepage.
6. Clear away the foreign matters in the impact stone crusher. Check the abrading and impacting of the rotors.
