The polyurethane modular screen is made of specially formulated polyurethane and high-strength steel belts. Combining the flexibility of polyurethane and the rigidity of steel belts, polyurethane modular screen panels have excellent performance in the screening industry.
has the characteristics of high wear resistance and long service life.
High wear resistance, long service life
Maintain accurate dimensions for a long time
Quick and simple installation and removal, reducing downtime
Self-release holes reduce hanging nails and blind holes
A variety of apertures are available, suitable for most applications
Wide panel size range, suitable for any frame or vibrating screen
Application range of polyurethane screen:
Steel plant, mining industry, cement plant, mineral processing plant, power plant coal washing.
Performance characteristics of polyurethane screen:
1. Good abrasion resistance and long service life. Its abrasion resistance is 3 to 5 times that of steel screens and more than 5 times that of ordinary rubber screens.
2, the maintenance workload is small, the polyurethane screen is not easy to be damaged, and the service life is long, so it can greatly reduce the maintenance volume and the loss of maintenance.
3. The total cost is low. Although the polyurethane screen of the same size (area) has a higher one-time investment (about 2 times) than that of the stainless steel screen, the life of the polyurethane screen is 3 to 5 times that of the stainless steel screen, and it is repaired and replaced. The number of times is small, so the total cost is not high, and it is very economical.
4. Good moisture resistance, it can work under the condition of water as the medium, and under the condition of water, oil and other media, the friction coefficient between polyurethane and the material is reduced, which is more conducive to screen penetration, improves screening efficiency, and can avoid wet particles At the same time, due to the reduced friction coefficient, the wear is reduced and the service life is increased.
5. Corrosion resistant, non-flammable, non-toxic and tasteless.
6. Due to the reasonable design of the sieve holes and the unique manufacturing process of the sieve plate, the particles of the extreme size will not block the sieve holes.
7. Good vibration absorption performance, strong noise reduction ability, can reduce noise, and make the screen material not easy to break during the vibration process.
8. Due to the secondary vibration characteristics of polyurethane, the polyurethane screen has a self-cleaning effect, so the screening efficiency is high.
9. Energy saving and consumption reduction, polyurethane has a small specific gravity and is much lighter than steel screens of the same size, thus reducing the load of the screen machine, saving power consumption, and extending the life of the screen machine.
Polyurethane screen is made of polyurethane elastomer. Polyurethane elastomer is a new type of synthetic material between rubber and plastic. It has strong abrasion resistance, wide range of hardness, high elasticity, heavy load, oil and ozone resistance , Radiation resistance, high tear strength, etc., is an indispensable engineering material in modern industry. The development, promotion and application of polyurethane screens is one of the national "Eighth Five-Year Plan" scientific and technological projects. It is suitable for coal, metallurgy, garbage disposal and other industries, and is mainly used for material screening, dehydration, and de-intermediation.
