Polyurethane screen, as a kind of screening equipment accessories with high wear resistance, corrosion resistance a

Polyurethane screen, as a kind of screening equipment accessories with high wear resistance, corrosion resistance and water immersion resistance, is widely used in mining, metallurgy, building materials and other industries. However, in actual production, the replacement cycle of the screen is often affected by many factors, among which the installation method of the polyurethane screen cannot be ignored. This article will explore the impact of polyurethane screen installation methods on the replacement cycle and propose some effective solutions.

First, we need to understand the installation method of polyurethane screen. There are usually three installation methods: fixed installation, movable installation and hybrid installation.

Fixed installation is to fix the screen on the screen surface. This method is suitable for screening materials with finer particle size; movable installation is to install the screen on a movable frame and is suitable for screening materials with larger particle size. ;Hybrid installation combines fixed and movable installations to adapt to screening materials of different particle sizes.

Different installation methods have a significant impact on the screen replacement cycle. Due to the tight combination of the screen and the screen surface, the fixed installation has less wear on the screen during the screening process, so the replacement cycle is longer. However, when the screen is partially worn, replacing the entire screen will cause greater waste. Although it is more convenient to replace the screen in the movable installation, due to the certain gap between the screen and the screen surface, the material wears the screen more during the screening process, resulting in a shorter replacement cycle. Hybrid installation combines the advantages of fixed and movable installation, which not only facilitates screen replacement, but also reduces screen wear, thereby extending the replacement cycle.

In order to further improve the service life of the polyurethane screen, we need to pay attention to the way the screen is fixed.

There are usually three fixing methods: bolt fixing, buckle fixing and adhesive fixing. Although bolt fixation is firm, disassembly is cumbersome and affects the replacement cycle; buckle fixation and adhesive fixation are easy to disassemble and help shorten the replacement cycle. However, the firmness of snap fixation and adhesive fixation is relatively low, which may affect the screening effect. Therefore, in practical applications, the appropriate fixing method should be selected according to the specific situation to take into account the replacement cycle and screening effect.

To sum up, the installation method and fixation method of polyurethane screen have an important impact on its replacement cycle. In actual production, the appropriate installation method and fixation method should be selected according to the particle size, screening effect and production needs of the material, in order to achieve the effect of extending the service life of the screen, reducing production costs and improving production efficiency. At the same time, we should also pay attention to the daily maintenance and maintenance of the screen, and promptly replace seriously worn screens to ensure the normal operation of the screening equipment.
