Manganese steel woven mesh is a type of screening mesh made from manganese steel (a wear-resistant alloy steel with high manganese content, such as Mn13) through a weaving process. It is widely used in high-load screening scenarios due to its excellent wear resistance and impact resistance. Core Characteristics High Wear Resistance: Manganese steel undergoes work hardening on its surface under impact loading, significantly increasing its hardness and enhancing wear resistance. It is suitable for processing high-hardness materials such as quartz sand and iron ore. Impact Resistance: The material features good toughness, capable of withstanding frequent impacts from materials like ores and aggregates, with low susceptibility to fracture or deformation. Corrosion Resistance: It demonstrates better stability than ordinary steel in wet or acid-base environments, though its chemical corrosion resistance is weaker than non-metallic materials like polyurethane.
Mining and Metallurgy: Used for coarse crushing screening of ores, blast furnace slag treatment, etc., to cope with impact and wear from large-particle and high-hardness materials.
Sand and Aggregates: Primary screening in manufactured sand production lines, such as grading after crushing granite and basalt, reducing screen mesh replacement frequency.
Building Materials and Power: Screening of concrete aggregates, impurity removal screening in coal conveying systems of thermal power plants.
Selection Recommendations
Suitable Scenarios: Where materials have high hardness and large impact loads (e.g., mine coarse crushing), or where temperature resistance is required (polyurethane screening meshes have poor temperature resistance).
Precautions: Anti-rust treatment should be done in humid environments. For fine-grain screening, low open area ratio easily causes hole blockage, so vibration devices need to be paired to improve screen penetration rate.
