Why is the dewatering screen not completely dewatering?

The reasons for the incomplete dewatering of the dewatering screen may be the influence of material properties, operational factors and working parameters. The following is a detailed introduction:

1. The influence of material properties

The vibration dewatering screen material with a particle size less than 3/4 of the mesh size is easy to steal through the sieve hole, which is called easy to screen; the particle is larger than 3/4 of the mesh size, and it is difficult to pass through the sieve hole. The effect of the special slurry dewatering screen used for water-coal slurry is called difficult to glue particles; the particle size is 1-1.5 times the mesh size. The particle is called a particle. Therefore, the screening contains a large amount of finer materials such as J, and the auxiliary screening method can be increased. The auxiliary screen with a larger mesh size is used to pre-screen the products on the screen.

2. The influence of operational factors

The dewatering screen should maintain a high screening efficiency, the feed should be uniform and continuous, and the vibrating screening machine should be fed moderately.

3. The influence of working parameters

    1. Screen surface type: The screen surface usually has steel bars, steel wires, punched steel plates, rubber, polyurethane, etc. Their influence on screening efficiency is mainly related to their area: In addition, the wear resistance of various materials is also different.

    2. Mesh shape: square or rectangular mesh application teaching.
