1. Components of impact crusher

An impact crusher generally consists of a feed port, a crushing chamber, an impact plate, a rotor, a discharge port, a screen plate, an adjustment device, a motor and a belt drive device. Among them, the impact plate is the core component of the crusher, which is installed on the rotor and directly contacts the material for crushing.

2. Working principle of impact crusher

When working, the material enters the crushing chamber from the feed port, collides with the high-speed rotating rotor, and is repeatedly hit and crushed by the impact plate, finally achieving the crushing effect. In this process, the impact plate repeatedly flips, discharges the crushed material through the discharge port, and removes impurities through the screen plate, thereby achieving the crushing and screening of the material.

3. Advantages and disadvantages of impact crusher

1. Advantages:

(1) The impact crusher has a simple structure, small size, light weight, and is easy to install and maintain.

(2) It has a wide range of applications and can be used to crush materials of various hardness.

(3) It has high crushing efficiency, relatively fine crushing, and less dust pollution.

(4) It can be well automated and has obvious advantages in production efficiency and energy utilization.

2. Disadvantages:

(1) The crushing ratio is not uniform enough, and the crushing fineness is not high enough, especially for large pieces of material.

(2) Since the rotor generates a certain centrifugal force when it rotates, it is necessary to consider the balance when feeding, otherwise it is easy to cause material blockage.

(3) For materials with certain toughness or high toughness, it is easy to cause damage or serious wear of the impact plate.

IV. Conclusion

The impact crusher is a widely used crushing equipment. It adopts advanced working principles and technologies, and can efficiently crush materials and screen out debris. Although the impact crusher has some disadvantages, its advantages are still widely recognized and it is a device worthy of promotion and application.
