Why Does The Drum Screen Get Clogged?

Date: 2025-02-07     From: Longding     Author: admin

The processing capacity of the drum screen is positively correlated with the effective opening rate of the screen. The larger the effective opening rate, the better the material is screened and the larger the processing capacity of the vibrating screen. When the vibrating screen is screening materials, the problem of screen blockage is often encountered.

In actual production applications, there are two factors that cause the effective opening rate of the vibrating screen to decrease (i.e., screen clogging). One is the proximity effect, which refers to the blockage caused by particles with a similar aperture to the screen mesh being embedded in the mesh. Another is the accumulation effect, which is mostly caused by the stickiness of the material or the accumulation and agglomeration caused by static adsorption. Therefore, to ensure the processing volume, the cleanliness of the screen mesh must be maintained.

Causes of Drum Screen Blockage

1. It 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 on the screen holes;

4. Static electricity occurs.

5. The material is fibrous.

6. There are many flake particles.

7. The wire diameter of the woven screen is too coarse.

8. The hole shape design of thicker screens such as rubber screens is unreasonable, and the top is small and the bottom is large, which causes the particles to get stuck.Screening materials with very fine.

9. Articles or high moisture content.
