polyurethane screen

Polyurethane screen mesh perforated classification, widely used in metallurgy, mining, coal, building materials, water conservancy, etc, are the steel plate punching sieve screen , weave net, stainless steel sieve and rubber products, with the sieve weight, high efficiency and hole, friction, impact resistance and tensile, long service life (stainless steel sieve is 2-3 times), low noise, easy installation, comprehensive benefits.
According to the structural forms are divided into four types:
1) inlaying
2) bolt connection
3) layering connection
4) screen hooked
The advantages of polyurethane screen
| 1, long service life, carrying capacity. Due to the use of wire rope for elastic polyurethane screen skeleton material, plus polyurethane itself has very high elastic modulus, high strength, high wear-resisting, absorbing shocks and high tensile strength, its carrying capacity is 2.5 times of rubber sieve. Its service life compared with ordinary metal net increase of 8-10 times, the stainless steel screen is 3 times, is a natural rubber 3.9 times, is now the world's best wear-resisting performance easy.the materials. The production material of polyurethane screen organic polymer elastomer, has excellent resistance to abrasion resistance, flexible, carrying capacity. Polyurethane screen production materials with special processing, to ensure the long-term alternating load never debonded.
| 2, high screening efficiency. Sieving inside consecrated, performance, high screening efficiency. Because of the polyurethane permeability is strong, Vertebral Angle of screen hole(140 °), it can effectively prevent the damp granule of adhesion, suitable for damp granule materials screen classification. Our polyurethane screen using imported raw materials, its elastomer and their good dynamic performance, expansion situations effectively avoid pore blocking phenomenon.
| 3, and wide application scope, professional suitability of any type, stronger and sieve can be mechanism. Pu shaiwang professional application in hydropower station, building materials and other metal minerals. 0.1 mm - 170mm range of all kinds of materials, screening, do not affect all wet-screened sieve efficiency. To 0.5 m - 3mm within the scope of the dehydration, demedium sieve, more fully show the superiority of polyurethane screen. Product water resistance, corrosion resistance, ageing, replace the maintenance convenience. Pu density is small (1.32 kg/m 3), light weight on the metal surface to reduce the production, consumption, thus can adapt to the development of large-scale screen.
| 4, screening high precision. Polyurethane screen production technology adopted mould casting process, aperture accurate, screening high quality, under the granularity material screening is able to conform to the requirements of the customers. Easy installation, maintenance is convenient, the product replacement for any type of extension, light weight, screening for installation and maintenance, replacement greatly reduced workload.
| 5, low noise, accord with national standard specifications of environmental noise. According to the actual measurement, the same machine using polyurethane screen can reduce the noise than metal net, and 5-20 db greatly reduce dust, which have a quiet and clean production environment.
| 6, significant economic benefits. Although the price is screening polyurethane rubber metal screen, but if the comprehensive consideration of the high screening efficiency and maintenance cost, service life, will discover factors, such as polyurethane screen surface to better overall metal surface. According to the survey, each using a ton of polyurethane rubber sieve can save steel 45 tons. Save maintenance cost more than RMB40,000. Therefore polyurethane sieving alternative steel sieve surface will be in the majority of enterprises.
