Impact crusher is a new type of high-efficiency crushing machinery and equipment for medium and fine crushing operations below medium hardness, so it is called impact crusher. The equipment can process materials with a side length of 100-500mm, and its compressive strength does not exceed 350 megapascals of various ores and rocks, with large crushing ratio, high work efficiency, good crushing effect and other characteristics, so it is widely used in construction, transportation, chemical industry and other fields.
Impact crusher
Feed size: ≤300-≤700 mm
Capacity: 30-800 t/h
Application: Widely used in various ores, such as granite, marble, limestone, feldspar, swallow stone, etc.
The working principle of the impact crusher
The main working part of the
impact crusher is a rotor with a plate hammer that rotates at high speed. The material block in the feeding machine is impacted by the plate hammer in the rotor rotation range (i.e., the hammering zone), and is thrown to the impact plate at high speed, and is impacted again, and then rebounds from the impact plate to the plate hammer, and continues to repeat the above process. On the way back and forth, the materials also collide with each other. Due to the blow of the material by the plate hammer, the impact with the impact plate and the collision between the materials, the material continues to produce cracks, loose and crushed, when the particle size of the material is less than the gap between the impact plate and the plate hammer, it is discharged.
Advantages of impact crusher
1. Simple structure, compact size, full energy utilization, simplified production process, small power consumption per unit product, strong production capacity.
2. The crushing ratio of trans crusher is large, the particle size of the product is uniform, and the large material is easier to be crushed, while the small material is not too small.
3. Under the condition of the same feeding particle size and production capacity, its mass coefficient is much greater than that of other crushers.
4. It is convenient to manufacture and maintain, there is no obvious unstable vibration during work, reducing a large amount of infrastructure work, and the production cost is low.
5. Strong automatic detection, stable operation, high safety factor, and has a sealing device system, low pollution and low noise.
The model of impact crusher is generally distinguished by the size of the feed port, the larger the size, the larger the size of the material that can enter, and the stronger the processing capacity. The more common ones are 1315mm feed port and 1520mm feed port, also called 1315 counterattack breaker, 1520 counterattack breaker.
