When the vibrating screen is in normal operation, various types of screen plugging will occur due to various characteristics and shapes of the material.
The main reasons for the blockage are as follows:
1. The moisture content of the material is high;
2. Spherical particles or materials having multiple contact points to the mesh holes;
3, static phenomenon;
4. The material has a fibrous material;
5. more flaky particles;
6. The woven mesh is thick;
7. The hole shape design of thicker screens such as rubber screens is unreasonable, and the particles are stuck. Because the sieved material particles are mostly irregular, the cause of clogging is also varied.
In order to effectively prevent the screen of the rotary screen from being blocked, measures should be taken for the reasons for the above-mentioned screen plugging:
1. When the material has finer particle size, more shale content, and smaller sieve size, moisture plays a decisive role in the clogging of the screen.
2. 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 selected in a targeted manner.
3. When the moisture is more than 8%, wet screening should be used.
4. For materials with more flake particles, it is necessary to change the particle crushing mode and the particle size matching of different crushing processes.
Reasonable adjustment of the tension of the screen is an effective method to reduce the hole blocking of the screen. Reasonable tensioning force causes the screen to generate a slight secondary vibration with the support beam, thereby effectively reducing the occurrence of the hole blocking phenomenon. The tensioning hook is made into a constant force tensioning mechanism, that is, a spring is attached to the tension bolt.
