Common polyurethane screens mainly include polyurethane mine screens and polyurethane dehydration screens. Polyurethane screen plates are used in metallurgy (iron ore, limestone, fluorite, cooling blast furnace slag, coke and other raw materials), non-ferrous metals, coal, chemicals, building materials and hydropower engineering, abrasive waste treatment, quarry and other industries. Mining, screening, grading and other industries.
The main performance and characteristics of polyurethane sieve plate are:
1. Good abrasion resistance, its abrasion resistance is 3 to 5 times that of steel sieve plates and more than 5 times that of ordinary rubber sieve plates.
2. The maintenance workload is small, the polyurethane screen is not easy to damage, and the service life is long, so it can greatly reduce the amount of maintenance and the loss of maintenance.
3. The total cost is low. Although the polyurethane screen of the same size (area) is one-time higher than the stainless steel screen (about 2 times), the life of the polyurethane screen is 3 to 5 times that of the stainless steel screen, and the number of maintenance and replacement So the total cost is not high, and it is economically very cost-effective.
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 and non-flammable.
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 be broken 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.
