How to choose the correct screen mesh according to the screening materials, I hope it will be helpful to everyone.
First of all, the screen mesh should be selected according to the materials to be screened and its purpose, whether it is used for classification or dehydration. The screen materials used for screening relatively wet materials and screening dry materials are different. For screening relatively humid materials with water, polyether type polyurethane screens should be selected, which can effectively prevent the impact of water and Hydrolysis causes the screen life to be shortened.
For screening dry materials and materials with relatively large particles, polyester-type polyurethane screens should be selected. The strength, wear resistance and load-bearing capacity of the screen are better, which effectively improves the use of the screen. life.
Then choose the structural form when installing the screen according to the aperture size of the screen. If the aperture is relatively large (aperture size above 60mm is recommended), it is recommended to use bolt-type fixing methods when installing the screen. Since the material particles processed by the large-aperture screen are relatively large, they have a greater impact on the screen. Choosing other structural fixing methods can easily cause loosening, which will shorten the life of the screen and damage the screen.
