What Are The Performance Advantages Of The Equipment For Breaking Back The Broken Stone

Last Update:2020-05-07 06:53:03

Impact crusher is a process of breaking stone by using impact crusher. The equipment includes impact crusher, impact sand making machine, etc. These equipment can be used in many stone production lines for ore crushing, etc. What are the performance advantages of impact crusher? How about the principle of breaking gravel? Let's have a brief understanding.

The impact crusher is mainly used to deal with the broken stone. Impact crusher is a kind of crushing machine which uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at high speed. When the material enters into the action area of the plate hammer, it collides with the plate hammer on the rotor and breaks. Then the material is thrown to the counterattack device to be broken again, and then it bounces back from the counterattack lining plate to the plate hammer action area to be broken again. From large to small, the material enters the first, second and third reaction chambers for repeated crushing until it is crushed to the required particle size and discharged from the discharge port. Note: adjusting the gap between the counter frame and the rotor can change the size and shape of the material.

The design structure of the impact crusher is as follows: the feed block is fed from the feed inlet. In order to prevent the feed block from flying out during crushing, a chain curtain is installed in the feed direction of the feed inlet. The feed block falls on the upper part of the grate screen, the small block falls to the lower part of the casing through the grate seam, and the large block of material slides onto the rotor along the screen surface. A plate hammer with a certain height is fixed on the circumference of the rotor, and the rotor rotates at a high speed by the action of the motor through the V-belt.

The material block falling on the rotor is impacted by the high-speed rotating plate hammer. After gaining kinetic energy, it impacts the impact plate at high speed, then rebounds from the impact plate, and collides with the material thrown out by the rotor in the crushing area. The space composed of screen, rotor, reaction plate and chain curtain is called front impact zone; the space composed of reaction plate and rotor is the second impact zone. After the materials are impacted and broken by each other in the front impact zone, they enter the second impact zone and are impacted and crushed again. The crushed material is discharged through the discharge port at the lower part of the casing.
