The uses and characteristics of polyurethane screen plates

polyurethane screen plates are suitable for screening materials of various properties, as well as wet and easy-to-clog materials such as coal, gangue, coke, and slaked lime. It overcomes the problem of screen sticking when various vibrating screens screen wet materials, and improves the output and reliability of the screening system.

1. Adopting the rolling conveying principle, the friction coefficient is small, the wear is light, and the mesh is not easy to be blocked.
2. The bracket adopts an integral shaft design, which ensures smooth operation, no vibration and low noise.
3. Internal roller shutter accessories are described separately, making planning simple and easy to replace and repair.
4. The roller body should be designed with a practical full sealing solution and be free of dust pollution.
5. Reliable operation, low-speed transmission, high transmission efficiency, low belt power, low energy consumption, and obvious energy-saving effect.
6. Different screen materials can be selected according to customer requirements, with standard screen holes, high screening efficiency, long service life and low maintenance costs.

Main performance and characteristics of polyurethane screen plate

1. Good wear resistance and long service life. Its wear resistance is 3 to 5 times that of steel screen plates and more than 5 times that of ordinary rubber screen plates.
2. The maintenance workload is small, the polyurethane screen plate is not easily damaged, and has a long service life, which can greatly reduce the maintenance workload and downtime maintenance losses.
3. Low total cost. Although the one-time investment of the polyurethane screen plate of the same specification (area) is higher than that of the stainless steel screen plate (about 2 times), the total cost is not high, and the service life of the polyurethane screen plate is 3 to 5 times that of the stainless steel screen plate, and the number of maintenance and replacement times is Less, economical.

4. It has good moisture resistance and can work under conditions using water as the medium. In the presence of water, oil and other media, the friction coefficient between polyurethane and materials is reduced, which is more conducive to screening, improves screening efficiency and avoids the adhesion of wet particles. At the same time, the friction coefficient is reduced, wear is reduced, and service life is extended.
5. Corrosion-resistant, non-flammable, non-toxic and odorless.
6. Due to the reasonable screen hole design and the manufacturing process of the sieve plate, particles of extreme size will not block the screen holes.
7. It has good vibration damping performance and strong silencing ability, which can reduce noise and make the screen less likely to break during vibration.
8. Due to the secondary vibration characteristics of polyurethane, the polyurethane screen plate has a self-cleaning function, so the screening efficiency is high.
9. Save energy and reduce consumption. Polyurethane has a small specific gravity and is much lighter than a steel screen of the same size, thereby reducing the load on the screening machine, saving power consumption, and extending the service life of the screening machine.
