The Working Principle and Outstanding Advantages of the Impact Crusher

The impact crusher is mainly used in metallurgy, chemical industry, building materials, hydropower and other materials that often require relocation operations, especially for the operations of mobile stone such as highways, railways, and hydropower projects. It can be processed according to the raw materials Different types, scales and finished material requirements adopt multiple configuration forms.

The impact crusher is a crushing machine that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at a high speed. When the material enters the impact area of the blower, it hits and breaks with the blower on the rotor, and then it is thrown to the counterattack device and broken again, and then rebounds from the counterattack liner. Return to the hammer action area to re-crush. This process is repeated. The material enters the first, second, and third impact chambers from large to small, and is repeatedly crushed until the material is crushed to the required size and discharged from the discharge port.

The stone falls directly into the high-speed rotating turntable from the upper part of the machine; under the action of high-speed centrifugal force, it collides with another part of the flying rocks around the turntable in an umbrella manner to produce high-speed collision and high-density crushing. After the stones hit each other, they will A vortex motion is formed between the turntable and the casing, causing multiple blows and crushes.

The impact crusher is named according to the working principle, that is, it uses the principle of impact crushing to crush materials. It is a crusher equipment that is finer than the jaw crusher. It is mainly used for fine crushing operations in the stone production line. The crusher cooperates to crush. The impact crusher has the following five advantages in the crushing process.

1. The impact crusher is more effective in processing materials with a large amount of moisture and effectively prevents materials from clogging.

When the water content of the processed material is too large, the feed chute and the impact plate of the impact crusher can be equipped with heating devices to prevent the material from sticking. The impact crusher does not need to be equipped with a bottom screen, which can effectively prevent clogging.

2. The impact crusher is applicable to a wider range of material hardness.

The plate hammer of the impact crusher is firmly fixed on the rotor with a mechanical clamping structure, and has a large moment of inertia when rotating with the rotor. Compared with the hammer crusher (the hammer head is in a suspended state), the rotor of the impact crusher has greater momentum, which is suitable for crushing harder materials, and at the same time, it consumes less energy.

3. It is convenient and flexible to adjust the discharging particle size, and the adjustment range is wide.

The impact crusher can adjust the discharge particle size in many ways, such as adjusting the rotor speed, adjusting the gap between the impact plate and the grinding chamber. The gap adjustment can be adjusted mechanically or hydraulically. The hydraulic adjustment system can be used to conveniently complete the gap adjustment by operating the button or the distance control system on the spot.

4. The wearing parts are small and the metal utilization rate is high.

The wear of the hammer of the counterattack rock breaker only appears on the side facing the material. When the rotor speed is normal, the feed material will fall to the surface of the blow hammer (blow surface), and the back and sides of the blow hammer are not worn. Even the wear on the side facing the material is very small. And the bottom grinding rod is easy to replace. The metal utilization rate of the impact crusher plate hammer can be as high as 45% -48%.

5. The replacement of spare parts of the impact crusher is simple and the maintenance cost is correspondingly reduced

Only 6 blow bars are installed on the rotor of the impact crusher, and the blow bars can be easily replaced with the designed special tools. It only takes one shift to replace a set of blow bars.
