Dewatering screen is also called tailing dry discharge screen. In addition to the excellent performance and function of ordinary dewatering screen, the tailing dry discharge screen is often combined with thickener for tailings dry discharge, which is a very good dewatering screen and tailings dry discharge equipment at present.
The following factors affect the uncleanness of dewatering screen:
The first is the influence of material properties
The vibrating dewatering screen material with the particle size less than 3 / 4 of the mesh size is easy to steal through the mesh, so it is called easy screening; when the particle size is larger than 3 / 4 of the mesh, it is difficult to pass through the mesh, so the effect of the special slurry dewatering screen used for coal water slurry is called the particle difficult to sizing; the particle whose particle size is 1-1.5 times of the mesh size is called the particle. Therefore, screening contains a large number of finer grades of finer materials, and auxiliary screening methods can be added. An auxiliary sieve with a larger mesh size is used to pre screen the grade of the product on the screen.
Second, the impact of operational factors
Dewatering screen should keep high screening efficiency, feed should be uniform and continuous, vibrating screen should be appropriate feeding.
3、 Influence of working parameters
1. Screen surface type: the screen surface usually has steel bar, steel wire, punching steel plate, 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.
At present, the concept of energy conservation and environmental protection has penetrated into all walks of life, so only the production of energy-saving and environmental protection equipment can meet the needs of most industries. Therefore, the manufacturer followed the domestic energy conservation and environmental protection policy and launched a series of dehydration screen products, which were well received by new and old users.
