How To Solve The Problem of Screen Plugging

When sieving with a vibrating screen, according to the nature of the material, various forms of screen holes will be blocked. The reasons for the sieve blockage are as follows:

1. Contains a large number of particles close to the separation point;
2. The material has a high water content;
3. Spherical particles or materials with multiple contact points to the sieve openings;
4. Static electricity will occur;
5. Materials with fibrous materials;
6. There are many flaky particles;
7. the woven screen wire is thick;
8. Thicker screens, such as rubber screens, have irrational hole designs that do not reach the upper, lower, and larger sizes, and cause particles to become stuck.

Because most of the material particles to be sieved are irregular, there are various reasons for clogging. In order to effectively prevent the screen from being blocked, measures should be taken against the reasons for the above-mentioned screen holes. When the particle size of the material is fine, the mud content is large, and the sieving particle size is small, the blockage of the screen by moisture will play a decisive role. When the moisture in the material is more than 5%, if the material is dried unconditionally, the sieve surface and the sieve hole should be targeted. When the moisture is greater than 8%, wet screening should be used. For materials with more flaky particles, it is necessary to change the crushing method of the materials and the particle size matching of different crushing methods. Reasonably adjusting the tension of the screen is an effective method to reduce the blocking of the screen. The reasonable tension makes the screen and the supporting beam generate a slight secondary vibration, thereby effectively reducing the occurrence of hole blocking. The specific method is, The tension hook is made into a constant force tension mechanism, that is, a spring is installed on the tension bolt.
