Product use: metallurgy (iron ore, limestone, fluorite, cooling blast furnace slag, coke, etc.) Screening, grading and other industries. The new structure pattern sieve plate with various format specifications and sieve hole sizes. It is especially commonly used in occasions with strong impact, high hardness and high wear resistance requirements. Sieve plates are used for fine crushing and screening of iron ore, raw coal classification, gold, building materials, and sand and gravel screening for hydropower and nuclear power projects.
Classification grade: 0.08, 0.1, 0.2, 0.3, 0.5, 0.75, 0.8, 1, 2, 2.5, 3, 4, 5, 6, 7, 8, 10, 12, 15, 18, 20, 25, 30 , 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 120, 150mm, etc. The above sieve holes are conventional sizes. Other specifications can be customized according to customer requirements.
Characteristics of Polyurethane Screen
1. Good abrasion resistance, long service life, with abrasion resistance of 3-5 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 amount of maintenance and the loss of maintenance.
3. The total cost is low. Although the polyurethane screen of the same specification (area) has a higher one-time investment (about 2 times) than the stainless steel screen, because the life of the polyurethane screen is 3-5 times that of the stainless steel screen, and maintenance And the number of replacements is small, 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 in the case of water, oil and other media, the friction between the polyurethane and the material is reduced, which is more conducive to screen penetration, improves screening efficiency, and can avoid moisture At the same time, due to the adhesion of particles, the friction coefficient is reduced, 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 limit size will not block the sieve holes.
7. Good vibration absorbing 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 characteristics of the secondary vibration 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, thereby reducing the load of the screen machine, saving power consumption and extending the life of the screen machine.
