Polyurethane sieve belongs to mining equipment for mines and quarries. Combined shaker and other mining equipment.
Chemical composition: polyurethane;
Chinese name: Polyurethane;
Polyurethane structure English name: polyurethane
Category: Polyurethane and Polyurethane crack sieve sieve dehydration
Preparation of sources: from binary or polyisocyanate and di- or polyvalent hydroxyl compound from the polymer.
Press polyurethane form sieve structure is divided into four categories:
1) Mosaic
2) bolt connection
3) layering connection
4) sieve coupling hook
Polyurethane wire mesh (wrapped wire twisted wire welded care network)
The material has a beautiful shape, bright color, light weight, high mechanical strength, heat insulation, sound insulation, corrosion resistance, weather resistance, do not re-decoration, various colors.
1, tensile strength, high tear strength, excellent wear resistance, resilience, and compression set, long service life.
2, with the metal substrate with strong, not easy to play and shedding layers.
3, surface finish, dimensional stability.
High-strength composite mesh, belongs to the field of screening technology equipment, used to solve ordinary screen intensity low, short life problems. It is composed by the Internet and the carrier network, the improvement that the Internet is a metal mesh, polyurethane care network care network, the polyurethane care network located below a wire mesh, it is vertical and horizontal grid intersects, its latitude and longitude article by constituting the steel cord and polyurethane skin. These improvements give the utility model is different from ordinary metal mesh excellent performance. It has high strength, rigidity and load carrying capacity, can effectively reduce vibration and noise, improve screen life. The utility model can be made into various shapes screening device, particularly suitable for high-frequency electromagnetic excitation vibrating mesh sieve. It can be widely used in many industries in the screening, filtration, dehydration, mud and other operations.

8mmX20mm hole two meters X5 meters
Hao coal, iron
Suitable shaker metallurgy, coal, chemical, construction and many other sectors, as the bulk material in the fine fraction sieve, sieve can dry. It can be used for certain corrosive materials classification.

Advantages of polyurethane sieve editor
1, long life, large carrying capacity. Due to the use of polyurethane elastic rope sieve skeleton material, coupled with the polyurethane itself has a very high elastic modulus, high strength to absorb impact, high abrasion resistance, which has high tensile strength, its carrying capacity is rubber sieve 2.5 times more. Its life compared with ordinary metal sieve increase 8-10 times, it is three times the screen surface of stainless steel, is 3.9 times of natural rubber, is the best material in the world on the screen surface wear. Polyurethane sieve production material is a high molecular organic elastomer, has excellent abrasion resistance, flex resistance, carrying capacity. Polyurethane sieve production of raw materials after the 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. Due to water seepage and strong polyurethane, mesh large cone angle (140 °), it is possible to effectively prevent the adhesion of moist fine grain composition, and therefore suitable for screening classification moist fine materials. I plant polyurethane sieve using imported raw materials, the elastic body and the relaxation of its good performance in the dynamic case effectively avoid clogging phenomenon.
3, for a wide range of professional suitability 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 selected from the mining industry. Screening within 0.1mm-170mm range of various materials, regardless of dry sieving, wet sieving have no affect screening efficiency. Dehydration within a 0.5m-3mm range sculping sieve, more fully show the superiority of polyurethane screen surface. Product water resistant, corrosion-resistant, anti-aging, replacement and easy maintenance. Polyurethane density (1.32kg / m 3), lighter in weight than metal mesh surface, can reduce production consumption, so they can 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 screening quality, size sieve materials can well meet the user's requirements. Installation is simple, 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 greatly reduce dust emissions, so that the production site has a quiet working environment clean.
6, significant economic benefits. Although the price of urethane rubber screen surface than the metal sieve high, but if considering the screening efficiency, maintenance costs, life and other factors, you will find the overall effectiveness of the polyurethane screen surface to be much better than ordinary metal sieve. According to the survey, with each one ton of polyurethane rubber sieve can save 45 tons of steel. Save maintenance costs 40,000 yuan. Therefore polyurethane screen surface replacement steel screen surface will be the inevitable choice for most enterprises in the future.
