Dry goods sharing: Factors affecting the service life of polyurethane sieve plate

2025-06-06

Polyurethane sieve plates are widely used in the sieving industry for their excellent physical properties and chemical stability. However, their service life is affected by various, and here are several key factors summarized based on the search results:

Use environment and conditions The use environment and conditions of the polyurethane sieve plate directly affect its service life. For example, the working of the sieve plate in water, oil and other media, the reduction of friction coefficient helps to penetrate the sieve and improve the screening efficiency, while reducing the adhesion of particles, thereby improving the service life. In addition, the design and installation method of the sieve plate are also crucial. For example, for large-aperture sieve (it is recommended that the aperture is more than 60mm), it is more appropriate to use the bolt-type fixed structure, because other forms of sieve net forms are easy to loosen, resulting in a shortened service life of the sieve net.
Materials and Processing Techniques The materials and processing techniques used in the production of polyurethane sieve plates significantly affect their performance and lifespan.-quality polyurethane materials and reasonable processing techniques can significantly enhance the abrasion resistance and service life of the sieve plates. For instance, under the same raw materials polyurethane sieve meshes, the main factor affecting their quality is the processing technique, including the treatment of molds and frames, as well as the control of temperature and stains. Additionally, the production materials of polyurethane sieve meshes belong to high-molecular organic elastic bodies, which have good abrasion resistance, flexural resistance and large bearing capacity, all of which are key factors determining their service life.
Maintenance and operation Proper maintenance and operation can maximize the performance of the polyurethane screen and extend its service life. For example, regular and tightening of the screen net's fastening bolts, ensuring that the material is discharged not perpendicular to the screen surface, the feed direction should be inclined along the direction of material, and the feed height should not exceed 400mm to prevent excessive impact from damaging the screen net. In addition, the self-cleaning performance of the polyureth screen also helps to improve the screening efficiency and extend the service life.

In summary, the service life of polyurethane screen decks is affected by a variety of factors such as the use environment and conditions, materials and processing technology, and operation, and design and structure. Understanding these factors and taking corresponding
