The granulated material particles are irregular. 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. When the moisture is greater than 8%, wet screening should be used. For materials with more flake particles, it is necessary to change the material crushing mode and the particle size matching of different crushing processes. When the material has a fine particle size, a large amount of shale, and a small sieve size, moisture clogging of the screen occurs.

Cause of blockage:

a more flake particles;
b spherical particles or materials having multiple points of contact to the mesh;
c material has a high water content;
d Thicker screens such as rubber screens, the hole shape design is unreasonable, does not reach the upper and lower, and the particles are stuck.
eThe screen mesh you selected is thick;
f contains a large number of particles close to the separation point;
g material has a fibrous material;
h will generate static electricity;

Suggestion: Adjust the tension of the screen, the reasonable tension of the dust-removing frame will cause the screen to produce a slight secondary vibration with the support beam, thus effectively reducing the phenomenon of screen plugging. The specific method is to make the tension hook The constant force tensioning mechanism, that is, the spring is attached to the tension bolt.

Daily maintenance should be done:

1. The outer surface of the filter bag has been treated with anti-corrosion treatment and electroplated according to customer needs. Spray or paint and silicone treatment, such as for high temperatures.
2. The circular dust-removing skeleton needs to be evenly distributed in the longitudinal and longitudinal ribs, and the material with the required strength and rigidity is selected, and the gas pressure of the filter bag during the filtration and cleaning process can be withstood, and also in the process of normal transportation and installation. The damage caused by the bumps and impacts of the seizures.
3. For the solder joints of the dust-removing skeleton, it should be welded and sturdy after inspection, and no desoldering is allowed. In the local area of ​​the virtual welding and the missing welding, repair the unqualified local time.

4. The appearance of the filter bag skeleton and the filter bag should be smooth and flat, and no soldering is allowed. Uneven areas such as unevenness and burrs.
5. The tension spring type skeleton should have the number of turns and elasticity, and the spacing should be even after the opening.
