Polyurethane classificated screen and plate, widely used in screening machine in metallurgy, mining, coal, building materials, water conservancy, etc, are the replacement of the steel plate punching sieve screen, steel wire weave screen, stainless steel sieve plate and rubber sieve screen , with the characteristics of light weight, high screening efficiency and not blocking hole, friction-resistant, impact resistance and tensile, long service life , low noise, easy to installation, comprehensive benefits.
According to the structural forms are divided into :
1) inlaying
2) bolt connection
3) layering connection
4) screen hooked
The advantages of polyurethane screen
1, long service life, big carrying capacity. Due to the use of wire rope as elastic polyurethane screen's 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 higher than rubber sieve screen. Its service life improve 8-10 times compared with ordinary metal screen , is 3 times than the stainless steel screen , 3.9 times than natural rubber , is now the best wear-resisting performance screen material in the world.The production material of polyurethane screen belongs to organic polymer elastomer, has excellent resistance to abrasion resistance, flexible, big carrying capacity. production materials of Polyurethane screen are special processed., to ensure never debonded in the long-term alternating load .
| 2, high screening efficiency. Sieving inside self-cleaning performance, high screening efficiency. Because of the polyurethane permeability is strong, big screen aperture cone Angle (140 °), it can effectively prevent the adhesion of damp granule , suitable for damp granule materials screen classification. Our polyurethane screen using imported raw materials, its elastomer and itself nice expanded performace, in dynamic situation effectively avoid pore blocking phenomenon.
| 3, wide application scope, higer professional applicability, it can apply to any type vibration screen machine and can be produced by measuring the machine. Polyurethane sieve screen professionally apply to in hydropower station, building materials and other metal minerals. 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. Polyurethane density is small (1.32 kg/m 3), lighter than metal screen, reduce the production, consumption, thus can adapt to the development of large-scale screen.
