Polyurethane screen panels is widely used in mining, coal and other engineering fields. When mining and extraction, using polyurethane sieve plates has many advantages. Because mine PU screen panels make full use of polyurethane's superior performance, it has both toughness and rigidity, meanwhile they are also acid,alkali and heat resistant, can ensure the screen gap stability during its use, and the greatest extent ensure the stability of the particle size after screening, and not easy to block holes. Coupled with its reasonable sieve structure and installation structure design, the polyurethane sieve plate has the following characteristics:

1. Better wear resistance and longer service life. Its wear resistance is 3~5 times that of steel sieve plate and more than 5 times than ordinary rubber sieve plate.
2.Less in maintenance and longer service life, it can greatly reduce the maintenance times and the loss for production shutdown and maintenance.
3. Lower total cost. Although the one-time investment (about 2 times) of the polyurethane screen panels is higher than that of the stainless steel trim panel under the same specification (area) , but polyurethane panels’ service life is 3~5 times that of the stainless steel panel, and the times of maintenance and replacement is less, the total cost is not high. It's also economical.
4. Good moisture resistance, can work under the condition of water as the medium, and also in the case of water, oil and other media, the friction coefficient between the polyurethane sieve plate and the screened material is reduced, which is more conducive to permeation, improve the screening efficiency, and can avoid moisture adhesion of particles. At the same time, due to the reduced friction coefficient, the wear is reduced and the service life increased.
5 Corrosion-resistant, non-flammable, non-toxic and tasteless.
6 Due to the reasonable hole design and the unique manufacturing process of the screen panels,the limit size particles will not block the panel’s holes.
7. Better vibration absorption performance. Strong muffling ability. PU vibration screen panels can reduce the noise and make the sieve material not easily broken during the vibration process.
8. Due to the characteristics of polyurethane secondary vibration, the polyurethane screen plate has a self-cleaning effect. Therefore, the screening efficiency is high.
9. Energy saving and consumption reduction, the proportion of polyurethane is small, and its weight is much lighter than that of the same size steel screen, thus reducing the load of the screening machine. Save power consumption. and prolong the life of the screen machine.
