The material on the screen surface is composed of particles of different sizes. When the material starts to enter the vibrating screen surface, the particles of different sizes are mixed together. Among these materials, only the lowermost material is in direct contact with the screen surface, which means that only the lowermost layer is smaller than the mesh size. Organically permeable.
In the process of vibration of materials with different sizes of particles, small particles will settle down through the gap between large particles. Large particles can be drilled due to seamlessness and are more and more settled to the bottom of small particles. It will gradually float upwards, and the final layer of material is arranged from top to bottom. We call this process the material layering process. Through the material layering process, the material smaller than the mesh hole is finally exposed to the sieve. The surface is sifted through the sieve to achieve the purpose of screening.
Therefore, the thinner the layer, the faster the layering of the material and the faster the screening.This is the reason why the equal-thickness screen adopts a large inclination angle in the feeding section, because the large inclination angle can increase the material flow rate, lower the layer height, achieve the purpose of rapid stratification and rapid permeable screening. The domestic probabilistic sieve utilizes a multi-layered screen surface to force the material to be quickly stratified to achieve rapid permeable screening.
When selecting a vibrating screen, consider the specific application. If it is necessary to use dewatering, then it is necessary to consider a dewatering shaker specially equipped with a dewatering function and a dewatering function. If the vibrating screen is to be used for screening, grading and recycling, the vibrating screen should be considered at the beginning of the design, and the corresponding components should be attached.
