     Welded screen is a metal mesh structural element used for screening and filtering. It is widely used in sieving, filtration, dewatering, and mud removal in many industries. It has high strength, rigidity and load-bearing capacity, and can be made into rigid screening and filtering devices of various shapes.

Product specifications: flat sieve plate. Arc sieve. Polyurethane sieve plate. Woven raw coal sieve bar screen. Uses: Manganese steel screens can be used in mining, coal, petroleum, fertilizer, food, environmental protection and other industries. Slot screens, petroleum filters, and salt industry nets. Manganese steel ore screens are made of manganese steel wire mesh. It is a screen product woven from 1.6mm-12mm silk threads. It uses the embedded (Mn65-Q) weaving method. The overlapping points of warp and weft are not prominent. The surface is flat and the force is uniform. The hardness is HB180-230, which has good plasticity and toughness. When subjected to strong impact and friction, the surface undergoes strong work hardening due to plastic deformation, and the surface hardness value can be increased to above HRC60 to obtain higher wear resistance, while the interior still maintains high plasticity and toughness. When the old surface is worn, the new surface will form a wear-resistant layer, so the service life can reach 4-8 times that of ordinary screens. Therefore, it is mostly used in large coal mines, and it can also be used in professional mechanical shaker screens and rollers. Screening machines, electromagnetic high-frequency screening machines, and asphalt mixers are used as protective nets.

Welding screen is a newly developed product recently developed in the family of mine screens, which is characterized by easy leakage, wear resistance and corrosion resistance. The mesh section is trapezoidal. The gap is narrow and wide. Can be widely used in mining, coal, petroleum, fertilizer, food, salt, environmental protection and other industries. Mine sieve product usage and classification method The cross section of the ore screen is trapezoidal, and the gap is narrow and wide. Generally speaking: mainly: filter cartridges, polyurethane sieve plates, flat sieve plates, and woven raw coal sieve bars Series of seam screens, petroleum filters, salt industry nets, centrifuge screen baskets, filters, stainless steel mesh covers, etc.

Product types and raw materials used to buy manganese steel screens. The number of meshes in the ore screen: The number of ore screens does not refer to the number of sieve holes in the entire screen. When choosing a vibrating screen, we must first make clear what material we are sieving, and then we can choose the screen that can meet our screening needs based on the size of the screened material particles. Describe the technical parameters such as mesh number, wire diameter, hole diameter, diameter, material, effective screen surface, etc. The unit of length is usually millimeter (mm).
