Detailed explanation of the working principle of the impact crusher
Principle description
The utility model utilizes a plate hammer on a rotor rotating at a high speed to generate a high-speed impact on the material fed into the crushing chamber of the impact crusher, causing the material to be broken, and the broken material is thrown at a high speed toward the counterattack plate at the other end of the crushing chamber along the tangential direction. Perform the above process again by breaking again and then rebounding from the counterplate to the hammer.
Then, the material is repeatedly broken into the first, second and third counter-attack chambers from large to small. During the operation of the crushing process, the material is hit by the hammer, the impact with the counter-attack and the collision between the materials, and the material is obtained. The higher crushing force and impact force are finally broken up to the required particle size and discharged from the discharge port.
Principle flow
First, according to the performance of the material to determine the way to choose when crushing, if small pieces of material, it is free to break. The material enters the crushing chamber, and on the one hand, it is subjected to the impact of the hammer. On the other hand, the materials also collide with each other. The friction between the hammer and the material, the material and the material is the external force that the material in the crushing chamber is broken. This principle of operation is only for relatively small pieces of material, because of the effect of gravity, so small pieces of material will be broken.
Second, the rebound process. It means that the material is concentrated in the box frame of the equipment, and the hammer is hit by the high-speed rotating impact crusher rotor, so that the material obtains a high moving speed and then hits the frame body, so that the material is further broken. A crushing process is called "bounce breakage."
Third, the shearing process. A kind of crushing for a larger material, that is, a material that is not broken by two kinds of crushing effects and larger than the size of the discharge port, is crushed by a hammer head that is rotated at a high speed at the discharge port. The particle size of the ultimate material can be adjusted according to the needs.
Folding wagons with canopies are a versatile and convenient type of outdoor utility cart that offer a range of benefits for users. They are designed to be lightweight, portable, and easy to store, making them an ideal choice for people who enjoy spending time outdoors.
