Vibrating screen is an indispensable screening equipment in daily industrial production. However, due to the characteristics of materials, various forms of screen hole blockage will be produced. In order to solve this problem, we found that the main reasons for screen hole blockage are listed below
1. The water content of the material is high, and many materials have fibrous materials
2. Contain a large number of meshes close to the separation point;
3. Spherical particles or materials with multiple contact points to the sieve;
4. Static electricity will occur;
5. More flake particles;
6. The wire diameter of the woven screen is too thick.
Since most of the material particles that need to be screened are irregular, the causes of blockage are also different. To effectively prevent the blockage of the vibrating screen, the following measures should be taken:
1. When the material particle size is finer, the mud content is more, and the sieving particle size is smaller, the water will play a decisive role in the blockage of the screen;
2. When the moisture in the material is greater than 5%, if the screen surface of the material is dried unconditionally, the screen surface and the screen hole should be selected in a targeted manner;
3. When the moisture is greater than 8%, wet screening should be used;
4. For materials with more flake particles, you need to change the material and use different crushing methods and particle size crushing processes.
