Introduce what are the features of commonly used screens

May. 23, 2023

As a precision screening equipment, the vibrating screen has a wide range of applications, and the screen is the primary component of the entire screening system. The correct selection of the screen is very important. It is in direct contact with the material during the production process. Once the raw material is not selected properly, it is easy to be damaged too quickly. At present, the raw materials of the screen are mainly divided into two types: metal and non-metal. Metal materials include low-carbon, high-carbon, high-manganese steel, stainless steel, etc. Non-metal materials are mostly rubber, nylon, and polyamide. In order to make it easy for us to choose correctly, the following is an introduction to the functions and characteristics of commonly used screens.

High manganese steel mesh High manganese steel has high strength, rigidity and bearing capacity, and the surface hardness value can be increased to above HRC60, so as to obtain high wear resistance, while the interior still maintains high plasticity and toughness. In addition, when the old surface is worn out, the new surface will form a wear-resistant layer, so the service life can reach 4-8 times that of ordinary screens. It is mostly used in large-scale mines, and can also be used as a protective net for mechanical vibrating screens. , drum screen machine, electromagnetic high-frequency screen machine and asphalt mixer, etc.

Among many raw materials, the most reliable one is high manganese steel mesh. It is a screen product made of manganese steel mesh with a wire diameter of 1.6mm-12mm. It adopts an embedded weaving method. The overlapping points of warp and weft are not prominent, the screen surface is flat, and the force is even. Plasticity and toughness can achieve better use effect, and at the same time, the service life is longer.

Polyurethane screen The production material of polyurethane screen is a polymer organic elastomer, which has good wear resistance, flex resistance, and large bearing capacity. After special treatment, it will delaminate under long-term alternating loads. Polyurethane screen is also a kind of better use and better wear resistance. Polyurethane itself has a very high elastic modulus, high strength to absorb impact force, high wear resistance, and high tensile strength.
