1. Long service life and large load-bearing capacity. Since the polyurethane elastic screen plate uses steel wire rope as the skeleton material, and 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 load-bearing capacity is more than 2.5 times that of the rubber screen plate. Its service life is 8-10 times longer than that of ordinary metal screen plates, 3 times that of stainless steel screen surfaces, and 3.9 times that of natural rubber. It is the screen surface material with the best wear resistance in the world. The production material of the polyurethane screen plate is a high-molecular organic elastomer, which is wear-resistant, flex-resistant, and has a large load-bearing capacity. The raw materials for the production of polyurethane screen plates 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, does not block holes, and has high screening efficiency. Our polyurethane screen plates use imported raw materials, and their elastomers and their own good relaxation properties can effectively avoid blockage under dynamic conditions.
3. Wide application range, stronger professional applicability, suitable for any type of vibrating screen machine and can be made by measuring machine. Polyurethane sieve plate is professionally used in hydropower stations, building materials and other metal beneficiation industries. Screening of various materials within the range of 0.1mm-170mm, whether dry screening or wet screening, does not affect the screening efficiency. For dehydration and de-mediation screening within the range of 0.5m-3mm, the superiority of polyurethane screen surface is more fully demonstrated. The product is water-resistant, corrosion-resistant, aging-resistant, and easy to replace and maintain. Polyurethane has a low density (1.32kg/m3) and is lighter than metal screen surface, which can reduce production unit consumption, so it can adapt to the development requirements of large-scale screening machines.
4. High screening accuracy. The production process of polyurethane sieve plate adopts mold casting molding process, with accurate aperture, high screening quality, and the particle size of the material under the screen can well meet the user’s requirements. Simple installation, convenient replacement and maintenance, this product is suitable for any type of screening machine, light weight, and greatly reduces the workload for on-site installation or replacement and maintenance.
5. Low working noise, in line with national environmental noise standards. According to actual measurements, the same sieve machine using polyurethane sieve plates can reduce noise by 5-20 decibels compared to metal sieve plates, and greatly reduce dust flying, thus providing a quiet and clean working environment at the production site.
6. Significant economic benefits. Taking into account factors such as screening efficiency, maintenance costs, and service life, it can be found that the overall benefits of polyurethane screening surfaces are significantly better than those of ordinary metal screening surfaces. According to the survey, using one ton of polyurethane rubber sieve plate can save 45 tons of steel. Save over 40000 yuan in maintenance costs. Therefore, replacing steel screen with polyurethane screen will be the inevitable choice for the vast majority of enterprises in the future.
