Product Introduction of Impact Crusher:
Impact crusher, which can also known as impact breaker or impact crushing machine, is mainly used for crushing of large, medium and small materials with side length less than 500mm and compression resistance less than 350Mpa. Zhongde stone impact crusher machine is an optimized crushing machine after adopting advanced techniques at home and abroad. The advantages of the products are big reduction ratio and cubic shape of the crushed materials .

Working principles of impact crusher:
When the hard rock counter-attacking crusher works, the electric motor drives the rotor where installed hammers to rotate with high speed . When the materials get into the area which the hammers can be effictive, under the impact function of the hammers at a high speed , the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers can be effective to be crushed in the impact chamber reqeatedly . The process won't stop till the material are crushed to the required size and then will be discharged from outlet.
The impact crusher has the advantages of the following five aspects in the process of crushing,
1. The impact crusher to deal with large amounts of wet materials more effective, effectively prevent material blockage. When the water content of the material is too large, the feed chute and the impact plate of the impact crusher can be equipped with heating device to prevent the bonding of the material.
The counterattack crusher should not be equipped with a bottom sieve plate to effectively prevent blockage.
2. The counter-type crusher suitable for the material hardness is more extensive. The plate hammer of the counterattack crusher is firmly fixed on the rotor by means of a mechanical clamping structure, which has a great moment of inertia when rotating with the rotor.
Compared to the Hammer crusher (the hammer head is overhanging), the rotor of the counterattack Crusher has greater momentum, adapts to the crushing of harder materials, and the energy consumption is lower at the same time.
3. It can be convenient and flexible adjustment of the granularity of the material, a wide range of adjustment The counterattack crusher can adjust the particle size of the material in a variety of ways, such as adjusting the rotor speed, adjusting the gap between the counterattack plate and the grinding cavity.
Gap adjustment can be adjusted by mechanical or hydraulic type, the use of hydraulic regulation system can be easily achieved through the in-place Operation button or transport control system to complete the adjustment of clearance.
4. wear of wearing parts is small, high metal utilization rate The wear of the hammer of the counterattack stone-breaking machine appears only on one side of the welcome material. When the rotor speed is normal, the feed will fall to the surface of the plate hammer (hit surface), the back and side of the plate hammer is not worn. Even the wear and tear on this side of the material is rarely worn. And the bottom grinding rod is easy to replace.
The metal utilization rate of the counterattack crusher plate hammer can be as high as 45%-48%.
5. The replacement of spare parts for counterattack crusher is simple and the maintenance cost is reduced accordingly
