Why is Polyurethane Screen Mesh Popular in the Coal Preparation Industry?

1. Polyurethane screen mesh has long service life and large bearing capacity


Because the polyurethane elastic screen uses steel wire rope as the skeleton material, and the polyurethane itself has a very high elastic modulus, high strength to absorb impact force, high wear resistance, so it has high tensile strength, and the bearing capacity is the same as that of the rubber screen. 2.5 times or more.


Its service life is 8 to 10 times longer than that of ordinary metal mesh, 3 times that of stainless steel weave mesh, and 3.9 times that of natural rubber. It is the screen surface material with the best wear resistance in the world.


The production material of polyurethane mesh is a macromolecule organic elastomer, which has excellent abrasion 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 be delaminated under long-term alternating loads.


2. Polyurethane screen mesh has high screening efficiency


Self-cleaning performance in the screen surface, no hole blocking, 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-grained materials, so it is suitable for the screening and classification of wet and fine-grained materials.


3. Polyurethane screen mesh has a wide range of applications and strong professional applicability


Polyurethane screen mesh is suitable for any type of vibrating screen mesh machine and can be produced by mass production. Polyurethane screen mesh is professionally used in hydropower stations, building materials and other metal processing industries.


Screening of various materials in the range of 0.1mm~170mm, no matter whether it is dry or wet, it will not affect the screening efficiency. For the dehydration and de-intermediation screens in the range of 0.5m~3mm, the superiority of the polyurethane screen mesh is more fully demonstrated.


The product is water-resistant, corrosion-resistant, aging-resistant, and easy to replace and maintain. Polyurethane has a low density (1.32kg/m³) and is lighter than the metal screen surface, which can reduce the unit consumption of production, so it can meet the requirements of large-scale development of screen machines.


4. Polyurethane screen mesh has high screening accuracy


The production process of the polyurethane screen adopts the mold casting process, the aperture is accurate, the screening quality is high, and the particle size of the material under the screen can well meet the user's requirements.


The installation is simple, the replacement and maintenance are convenient, and the polyurethane screen mesh made by industrial screen manufacturer is suitable for any type of screening machine.


5. Low working noise of polyurethane screen mesh


According to the actual measurement, the same screen machine using polyurethane screen can reduce noise by 5~20 decibels than metal screen, and greatly reduce dust flying, so that the production site has a quiet and clean working environment.


6. Significant economic benefits of polyurethane screen mesh


Although the price of polyurethane rubber screen surface is higher than that of metal screen mesh, if factors such as screening efficiency, maintenance cost and service life are comprehensively considered, it will be found that the overall benefit 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 for every ton of polyurethane screen mesh used. Save more than 40,000 yuan in maintenance costs. Therefore, the replacement of steel screen surface by polyurethane screen surface will be the inevitable choice for most enterprises in the future.
