Advantages of Polyurethane Screens

Advantages of Polyurethane Screens:

1. Long service life and large carrying capacity. Since the polyurethane elastic screen uses steel wire rope as the skeleton material, and polyurethane itself has a very high elastic modulus, high strength to absorb impact force and high wear resistance, it has high tensile strength, and its carrying capacity is that of rubber screen. 2.5 times or more. Its service life is 8-10 times higher than that of ordinary metal screens, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. Polyurethane screens are currently the best screen material in the world for wear resistance. The production material of polyurethane screen is a polymer organic elastomer, which has excellent wear resistance, flex resistance and large bearing capacity. The raw materials for the production of polyurethane screens have been specially treated to ensure that they will never delaminate under long-term alternating loads.

2. High screening efficiency. The screen surface has self-cleaning performance, no hole blocking, and high screening efficiency. Due to the strong water permeability of polyurethane and the large sieve cone angle (140°), it can effectively prevent the adhesion of wet fine particles, so it is suitable for the screening and classification of wet fine particles. The polyurethane screen of our factory adopts imported raw materials, and its elastic body and its own good relaxation performance can effectively avoid hole plugging under dynamic conditions.

3. It has a wide range of applications and stronger professional applicability. It is suitable for any type of vibrating screen machine and can be made by measuring machine. Polyurethane screens are professionally used in hydropower stations, building materials and other metal beneficiation industries. Screening of various materials within the range of 0.1mm-170mm, regardless of dry sieving or wet sieving, will not affect the screening efficiency. The superiority of the polyurethane screen surface is more fully demonstrated for the dehydration and mediation sieve within the range of 0.5m-3mm. Polyurethane screen products are water-resistant, corrosion-resistant, aging-resistant, and easy to replace and maintain. The density of polyurethane is small (1.32kg/m 3 ), and the weight is lighter than the metal screen surface, which can reduce the unit consumption of production. Therefore, the screen mesh can meet the requirements of large-scale development of the screen machine.

4. Significant economic benefits. Although the price of polyurethane rubber screen surface is higher than that of metal screen plate, if the factors such as screening efficiency, maintenance cost and service life are considered comprehensively, it will be found that the overall benefit of polyurethane screen surface is much better than that of ordinary metal screen surface.
