_ Advantages of polyurethane sieve price wholesale high quality polyurethane sieve polyurethane sieve editing a long life, large carrying capacity. Since the polyurethane elastic sieve skeleton material used for the wire rope, together with the polyurethane itself has a very high elastic modulus, high strength to absorb impact, high wear resistance, which has high tensile strength, its carrying capacity is rubber sieve 2.5 times more. Its life improved as compared with ordinary metal screen 8-10 times, three times the screen surface is stainless steel, and is 3.9 times the natural rubber, is the best material in the world on the screen surface wear resistance. Polyurethane sieve material is a polymer organic production of elastomers, with excellent abrasion resistance, flex resistance, carrying capacity. Polyurethane sieve production of raw materials through a special treatment to ensure the long-term under alternating loads never delamination. 2, high screening efficiency. Its self-cleaning properties within the screen surface, no clogging, high screening efficiency. Polyurethane water permeability due to strong, large mesh cone angle (140 °), it is possible to effectively prevent moist fine particles were adhered, and therefore suitable for screening classification moist fine materials. 3, for a wide range of professional applicability stronger, applicable to any type of shaker machine and the amount of machine production. Polyurethane sieve used in professional hydropower, building materials and other metal mining election. Screening within 0.1mm-170mm range of various materials, whether dry sieving, wet sieving have no affect screening efficiency. Dehydration within a range of 0.5m-3mm, sculping sieve, more fully show the superiority of polyurethane screen surface. Product water resistant, corrosion-resistant, anti-aging, replacement and maintenance. Density polyurethane (1.32kg / m 3), lightweight metal screen surface, can reduce production consumption, and therefore able to adapt to the requirements of large-scale development of the screening machine. 4, high screening accuracy. Polyurethane sieve production process using die-casting process, the aperture accurate, high-quality screening, size sieve materials can well meet the user's requirements. Simple to install, easy to replace maintenance, the product is suitable for any type of screening machine, light weight, for on-site installation or replacement of maintenance, greatly reducing the workload. 5, low noise, in line with national standards of environmental noise specifications. The actual measured according to the same machine using polyurethane sieve sieve sieve than a metal can reduce the noise 5-20 dB, and significantly reduce dust emissions, so that the production site has a quiet working environment clean. 6, significant economic benefits. Although the price of polyurethane rubber, metal sieve screen surface than high, but if considering the screening efficiency, maintenance costs, life and other factors, you will find that the overall effectiveness of polyurethane screen surface to be much better than ordinary metal screen surface. According to the survey, with each one ton of polyurethane rubber sieve can save 45 tons of steel. Saving maintenance costs 40,000 yuan. Therefore, the screen surface to replace steel polyurethane screen surface will be the inevitable choice for most enterprises in the future. Polyurethane is a high strength, high wear-resistant materials, ranging from general rubber and plastic polymers between, he has a high elasticity of rubber can be, there are high-strength plastic, is a unique high wear elastic material polyurethane sieve belong mining equipment for mining and quarries. Combined shaker and other mining equipment
