Polyurethane screens and the difference between ordinary met

Polyurethane screens and the difference between ordinary metal mesh : mesh, woven wire mesh , stainless steel and rubber sieve sieve replacement products , light weight, high efficiency, non- clogging , anti-friction , impact resistance, tear crack , long life ( 2-3 times a stainless steel sieve ) , low noise , easy installation, comprehensive benefit advantages.
     Polyurethane mesh metal mesh compared with the ordinary :
     1 its long life , large carrying capacity . Since the polyurethane elastic wire mesh used as matrix material, plus the polyurethane itself has a very high elastic modulus, high strength to absorb impact , high wear resistance , which has a high tensile strength , its carrying capacity is a rubber mesh more than 2.5 times . Its life increased compared with the ordinary metal mesh 8-10 times the surface of the stainless steel sieve three times 3.9 times the natural rubber , is the world's best sieve material wear . Polyurethane mesh production materials are organic polymer elastomer with excellent abrasion resistance, flex resistance , large carrying capacity . Polyurethane mesh production of raw materials through a special treatment to ensure the long-term alternating loads never delamination .
     2 high screening efficiency . The inner screen surface self-cleaning properties , not plugging holes , high screening efficiency . Strong due to seepage of polyurethane , mesh cone angle is large (140 °), it is possible to effectively prevent adhesion of tablets to moist fine , so the material is suitable for wet fine sieve classification . Polyurethane screen using imported raw materials , elastomers and their own good Chi Chang performance in dynamic situations effectively avoid clogging phenomenon .
     3 screening high accuracy. Polyurethane mesh production process using die casting molding process , the aperture is accurate, high-quality screening , sieve particle size of the material can well meet the requirements of users .
     4 for a wide range professional suitability stronger, for any type of shaker machine and the amount of machine production. Polyurethane mesh used in professional hydropower , building materials and other metal selected mining . 0.1mm-170mm range screening of various materials , whether dry sieving , wet sieving have no impact on screening efficiency . On the 0.5m-3mm wide dehydration, medium sieve, more fully show the superiority of polyurethane screen surface . Product water resistance, corrosion resistance, aging , replacement and easy maintenance. Polyurethane density (1.32kg / m 3), the metal mesh surface and light weight , can reduce the production consumption , it can adapt to the development of large-scale screening machine requirements.
     5 and simple installation , replacement , easy maintenance, the product is suitable for any type of screening machine , light weight, for on-site installation or replacement maintenance, greatly reducing the workload.
     In summary, high abrasion polyurethane with metal mesh sieve grading irreplaceable advantages, but also coal beneficiation industry screening machinery using vibration sieve the best choice.
