Polyurethane mine screen
Polyurethane grading screens and screens are widely used in the screening machines of metallurgy, mining, coal, building materials, water conservancy, road construction and other industries. They are the replacement products of steel plate punching screens, steel wire woven meshes, stainless steel mesh plates, and rubber sieve plates. , With light weight, high screening efficiency, no blocking hole, anti-friction, impact resistance, tear resistance, long life (2-3 times that of stainless steel sieve), low noise, easy installation, high comprehensive benefits.
There are four types of polyurethane screen plate structure:
1) Mosaic
2) Bolt connection
3) Batten connection
4) Screen hook connection
Polyurethane Screen Advantages
1, long service life, large carrying capacity. Because polyurethane elastic mesh uses wire rope as skeleton material, together with polyurethane itself has a very high elastic modulus, high-strength impact force, high wear resistance, and therefore has a high tensile strength, its load carrying capacity is a rubber mesh 2.5 times more. Its service life is 8-10 times that of ordinary metal screens, 3 times that of stainless steel screens, 3.9 times that of natural rubber, and it is the best screen material available in the world for wear resistance. Polyurethane mesh production materials are high-molecular organic elastomers, with excellent wear resistance, flex resistance, and large bearing capacity. Polyurethane screens have been specially treated to ensure that they will never delaminate under long-term alternating loads.
2, high screening efficiency. Self-cleaning performance within the screen surface, no plugging holes, high screening efficiency. Due to the strong permeability of polyurethane and the large screen angle (140°), it can effectively prevent the adhesion of wet fine particles, so it is suitable for sieving and classification of moist fine materials. Our factory polyurethane screen adopts imported raw materials, its elastomer and its own good relaxation performance, in the dynamic situation to effectively avoid plugging phenomenon.
3, a wide range of applications, professional applicability is stronger, for any type of shaker and machine production. Polyurethane screens are used in hydropower, building materials and other metal mining industries. The screening of various materials within the range of 0.1mm-170mm, regardless of dry sieve, wet sieve does not affect the screening efficiency. Dehydration and desorption screens in the range of 0.5m-3mm more fully show the superiority of the polyurethane screen surface. The product is water-resistant, corrosion-resistant, aging-resistant and easy to replace and maintain. Polyurethane density is small (1.32kg/m3), lighter weight than metal screen surface, can reduce production unit consumption, so it can meet the requirements of large-scale development of the screening machine.
4, the screening accuracy is high. Polyurethane mesh production process using mold casting process, accurate pore size, high screening quality, the size of the material under the sieve can meet the user's requirements. Easy to install, easy to replace and overhaul, the product is suitable for any type of screening machine, light weight, for on-site installation or replacement maintenance, greatly reducing the workload.
5. It has low noise and meets the national environmental noise standards. According to the actual measurement, the same screen using polyurethane screen can reduce the noise by 5-20dB compared with metal screen, and greatly reduce the dust flying, so that the production site has a quiet and clean working environment.
6, significant economic benefits. Although the price of polyurethane rubber screen surface is higher than that of metal screen mesh, if the factors such as screening efficiency, maintenance cost, and service life are comprehensively considered, it will be found that the overall effectiveness of polyurethane screen surface is much better than that of ordinary metal screen surface. According to the survey, 45 tons of steel can be saved per ton of urethane rubber screen. Saving maintenance costs more than 40,000 yuan. Therefore, replacing the steel screen surface with polyurethane screen surface will be the inevitable choice for most enterprises in the future.
