The difference between polyurethane screen and ordinary metal screen

The replacement product of screen, wire mesh, stainless steel screen plate and rubber screen plate has the advantages of light weight, high screening efficiency, no hole blocking, anti-friction, impact resistance, tear resistance, long life (2-3 times that of stainless steel screen plate), low noise, easy installation, and high comprehensive benefits.
1. It has a long service life and large bearing capacity. Since the polyurethane elastic screen uses steel wire rope as the skeleton material, and the polyurethane itself has a very high elastic modulus, high strength to absorb impact force, and high wear resistance, it has a very high tensile strength, and its bearing capacity is more than 2.5 times that of the rubber screen. Its service life is 8-10 times higher than that of ordinary metal screens, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. It is currently the screen material with the best wear resistance in the world. The production material of polyurethane screens is a high molecular organic elastomer, which has excellent wear resistance, flex resistance, and large bearing capacity. The raw materials for the production of polyurethane screens have been specially treated to ensure that they will never delaminate under long-term alternating loads.
2. High screening efficiency. The screen surface has self-cleaning properties, no clogging, and high screening efficiency. Because polyurethane has strong water permeability and a large cone angle of the screen hole (140°), it can effectively prevent the adhesion of wet fine particles, so it is suitable for screening and grading of wet fine particles. The polyurethane screen uses imported raw materials, and its elastomer and its own good relaxation performance can effectively avoid clogging under dynamic conditions.
3. High screening accuracy. The production process of polyurethane screen adopts mold casting molding process, with accurate aperture, high screening quality, and the particle size of the screened material can meet the user's requirements well.
4. Wide range of applications, stronger professional applicability, suitable for any type of vibrating screen machine and can be made by measuring machine. Polyurethane screen is professionally used in hydropower stations, building materials and other metal beneficiation industries. Screening of various materials in the range of 0.1mm-170mm, whether dry screening or wet screening, does not affect the screening efficiency. For dehydration and de-mediation screening in the range of 0.5m-3mm, the superiority of polyurethane screen surface is more fully demonstrated. The product is water-resistant, corrosion-resistant, and aging-resistant, and is easy to replace and maintain. Polyurethane has a low density (1.32kg/m3) and is lighter than metal screens, which can reduce production unit consumption, so it can adapt to the requirements of large-scale development of screens.
5. Moreover, it is simple to install and easy to replace and repair. This product is suitable for any type of screening machine. It is light in weight and can be installed on site or replaced and repaired, which greatly reduces the workload.
In summary, the high wear-resistant polyurethane grading screen has irreplaceable advantages over metal screens, and is also the best choice for the use of screens in vibrating screening machinery in the mineral processing and coal processing industry.
