1. Long service life and large carrying capacity. Since the polyurethane elastic sieve plate uses the steel wire rope as the skeleton material, and the polyurethane itself has a very high elastic modulus, high strength absorbs impact force and high wear resistance, and thus has high tensile strength, and its load carrying capacity is a rubber sieve plate. More than 2.5 times. Its service life is 8-10 times higher than that of ordinary metal sieve plates, 3 times that of stainless steel sieve surface and 3.9 times that of natural rubber. It is the best screen surface material in the world. The production material of the polyurethane sieve plate is a polymer organic elastomer, and has abrasion resistance, flex resistance and load 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 self-cleaning performance of the sieve surface is not blocked and the screening efficiency is high. Due to the strong water permeability of the polyurethane and the large taper angle of the mesh (140°), the adhesion of the wet fine particles can be effectively prevented, and thus it is suitable for the screening and classification of the wet fine material. The polyurethane sieve plate of our factory adopts imported raw materials, its elastomer and its own good relaxation performance, effectively avoiding the phenomenon of plugging under dynamic conditions.
3, a wide range of applications, professional applicability is stronger, applicable to any type of vibrating screen machine and can be made by measuring machine. Polyurethane sieve plates are used in hydropower stations, building materials and other metal mining industries. Screening of various materials in the range of 0.1mm-170mm, regardless of dry sieve or wet sieve, does not affect the screening efficiency. The dewatering and de-screening in the range of 0.5m-3mm more fully demonstrates the superiority of the polyurethane screen surface. The product is water resistant, corrosion resistant, aging resistant and easy to replace and maintain. The polyurethane has a low density (1.32kg/m 3 ) and is lighter than the metal mesh surface, which can reduce the production unit consumption, so it can adapt to the large-scale development requirements of the screen machine.
4. High screening accuracy. The production process of the polyurethane sieve plate adopts the mold casting molding process, the aperture is accurate, the screening quality is high, and the particle size of the material under the sieve can well meet the requirements of the user. Easy to install, easy to replace and repair, this product is suitable for any type of screening machine, light weight, on-site installation or replacement inspection, greatly reducing the workload.
5, low noise, in line with national environmental noise standards. According to the actual measurement, the same sieve machine uses a polyurethane sieve plate to reduce the noise by 5-20 decibels than the metal sieve plate, and greatly reduces the dust flying, so that the production site has a quiet and clean working environment.
6. Significant economic benefits. Although the price of the urethane rubber screen is higher than that of the metal sieve, if the screening efficiency, maintenance cost, service life and other factors are comprehensively considered, the overall benefit of the polyurethane screen surface is much better than that of the ordinary metal screen surface. According to the survey, each ton of urethane rubber screen can save 45 tons of steel. Saving maintenance costs of more than 40,000 yuan. Therefore, the replacement of steel screen surface with polyurethane screen surface will be an inevitable choice for most enterprises in the future.
