Description
The rotor of the impact crusher is the "heart" of the crusher, and it is also a strict part of the impact crusher acceptance, which plays a vital role in the work. Therefore, the company has developed and produced a strong structure of the heavy rotor to obtain a higher moment of inertia. High wear-resistant materials and crushing cavity, making the performance of the crusher outstanding. The bearing seat adopts integral cast steel structure and unique plate hammer fixing device, which makes the plate hammer more reliable. The improved adjustment device reduces the time of shutdown and maintenance. The self-contained top opening device can quickly complete the replacement of vulnerable parts such as hammers. Selection of bearing specifications, higher carrying capacity. The rotor is analyzed to ensure stability and reliability.
Working principle
Impact crusher is a kind of crushing machinery that uses impact energy to crush materials. When the material enters the action area of the plate hammer, it is broken by the high-speed impact of the plate hammer, and is thrown to the counterattack device installed above the rotor to be broken again, and then bounces back to the action area of the plate hammer from the counterattack liner to be broken again. This process is repeated until the material is crushed to the required particle size and discharged from the lower part of the machine. Adjusting the gap between the counterattack frame and the rotor frame can achieve the purpose of changing the particle size and shape of the material. The machine adopts spring safety device behind the counterattack plate. When the non-broken materials enter the crushing chamber, the front and rear counterattack frames retreat and the non-broken materials are discharged from the machine.

It is a kind of crushing machinery that 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 the action area of the plate hammer, it collides with the plate hammer on the rotor and is then thrown to the counterattack device to be broken again, and then bounces back to the action area of the plate hammer from the counterattack liner to be broken again. This process is repeated. The material enters the three counterattack cavities of the 1. 2. from large to small to be broken until the required size, discharge from the discharge port. Adjusting the gap between the counter-attack frame and the rotor can achieve the purpose of changing the material discharge particle size and material shape. The stone directly falls into the high-speed rotating turntable from the upper part of the machine. Under the action of high-speed centrifugal force, high-speed collision and high-density crushing will occur with the flying stones distributed around the turntable in an umbrella-shaped manner. After hitting each other, the stone will form eddy current motion between the turntable and the casing, causing multiple mutual blows, friction and crushing, and will be discharged through the lower part. Form a closed circuit for many times, controlled by the screening equipment to achieve the required particle size.

Then it is thrown to the counterattack device to be crushed again, and then it bounces back to the hammer action area from the counterattack liner to be crushed again. This process is repeated. The material enters the counterattack cavity of the 1. 2. from large to small and is repeatedly crushed until the required size, discharge from the discharge port. Adjusting the gap between the counter-attack frame and the rotor can achieve the purpose of changing the material discharge particle size and material shape.
Impact crusher is a crushing equipment widely used in the market at present. The equipment is mainly used for intermediate crushing operation of crushed materials. It is very targeted for crushing materials. It is widely used in building materials, mining, metallurgy, chemical industry, water conservancy, hydropower, highway, railway and other fields, and is favored by the majority of users.
Working principle of impact crusher
First, the impact crusher motor drives the rotor to rotate through the triangular belt. At this time, the plate hammer on the rotor is in a radioactive state under the action of centrifugal force. When the material enters the rotation range of the plate hammer from the material inlet, it is impacted by the high-speed operation plate hammer and thrown to the impact plate along the tangential direction of the plate hammer rotation. Then, it returns from the counter plate to the rotation space of the plate hammer and enters the impact zone of the second counter plate. The material is subjected to the repeated impact of the plate hammer, the counterattack plate and the impact in the crushing cavity, which continuously produces cracks along the joint surface of the joint itself, and the internal organization is damaged, loosened and fragmented. Particles smaller than the crushing requirements are discharged out of the machine along the gap between the hammer and the counterattack plate, which becomes the crushed product.
