What Are the Advantages of Polyurethane Screen Compared with Metal Screen

Compared with polyurethane screen and metal screen:

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

Since 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 and high wear resistance, it has high tensile strength, and its bearing capacity is the same as that of the rubber screen. 2.5 times or more. Its service life is 8-10 times longer than that of ordinary metal screens, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. It is the screen material with the best wear resistance in the world. The production material of PU 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. It is a high-strength composite polyurethane wire mesh, which belongs to the technical field of screening equipment, and is used to solve the problems of low strength and short service life of ordinary wire meshes. It is composed of a net and a supporting net. It is a grid that intersects vertically and horizontally, and its warp and weft bars are all composed of a steel cord core and a polyurethane surface. It has high strength, rigidity and bearing capacity, and can effectively reduce vibration noise and improve the service life of the screen. It can be made into various shapes of screening devices, especially suitable for electromagnetic excitation of high-frequency vibrating screen. It can be widely used in screening, filtration, dehydration, desliming and other operations in many industries.

2. Polyurethane screen has high screening efficiency

The screen surface has self-cleaning performance due to the self cleaning screen mesh, 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 moist fine particles, so it is suitable for the screening and classification of moist fine particles. The polyurethane screen adopts imported raw materials, and its elastomer and its own good relaxation properties can effectively avoid the phenomenon of hole blocking under dynamic conditions.

3. High screening accuracy

The production process of the pu 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.

4. Wide range of application, stronger professional applicability, suitable for any type of vibrating screen machine and can be produced in quantity

Polyurethane screens are professionally used in hydropower stations, building materials and other metal beneficiation 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 dehydration and de-intermediation sieves in the range of 0.5m-3mm, the superiority of the polyurethane sieve surface is more fully demonstrated. The product provided by industrial screens manufacturers 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 a metal screen surface, which can reduce the unit consumption of production, so it can meet the requirements of large-scale development of screen machines.

Moreover, the installation is simple and the replacement and maintenance are convenient. The product is suitable for any type of screening machine. It is light in weight and can be installed or replaced on site, which greatly reduces the workload.
