Material

• High-carbon steel: It is favored for its remarkable strength and hardness. In the harsh environment of quarries and mines, high-carbon steel wire crimp screens can endure the substantial impact and friction from ores and rocks during the screening operation.
• Stainless steel: Grades like 304 and 316 are commonly used. Stainless steel offers excellent corrosion resistance, making it ideal for mining environments where exposure to moisture, chemicals, and various minerals is common.
• Alloy steel: With the addition of alloying elements such as manganese, chromium, and vanadium, alloy steel enhances the screen mesh's strength, toughness, and wear resistance. This makes it suitable for applications involving high-impact and high-abrasion conditions.

Feature

• Outstanding wear resistance: The crimping process and the use of wear-resistant materials result in a screen mesh that can withstand the abrasive action of sharp-edged ores and rocks over an extended period.
• High strength and stability: The interlocked crimped structure provides enhanced strength and stability, enabling the screen to bear heavy loads and high-pressure impacts during operation without significant deformation or breakage.
• Optimal permeability: The precisely designed crimped pattern ensures uniform and appropriate mesh openings, allowing for efficient passage of materials while effectively separating particles of different sizes.
• Good corrosion resistance: When made from stainless steel or alloy steel with anti-corrosion properties, the screen mesh can resist rust and corrosion, even in harsh and humid mining environments, thereby prolonging its service life.

Production Process

• Wire drawing: The raw metal material, in the form of rods or coils, is drawn through a series of dies to reduce its diameter and achieve the desired wire thickness with high precision and surface smoothness.
• Crimping: The drawn wires are fed into a crimping machine, which forms regular crimps or waves at specific intervals along the length of the wire. This crimping process is crucial as it determines the shape and structure of the mesh.
• Woven: The crimped wires are then woven together using specialized weaving machines. The weaving process can be either plain weave, twill weave, or other more complex patterns, depending on the specific requirements of the screen mesh.
• Finishing: After weaving, the screen mesh may undergo additional finishing processes such as cutting to the required size and shape, edge treatment to remove sharp edges and burrs, and surface coating or treatment to enhance its corrosion resistance and durability.

Specification

• Mesh size: It typically ranges from a few millimeters to tens of millimeters, with common specifications including 3mm×3mm, 6mm×6mm, 12mm×12mm, and 25mm×25mm. The choice of mesh size depends on the particle size distribution of the materials to be screened.
• Wire diameter: Usually falls within the range of 1.5mm to 25.4mm. Thicker wire diameters are employed for applications involving large and heavy materials to ensure sufficient strength and durability, while thinner wires are used for finer screening operations.
• Panel size: The width of the woven wire crimp screen mesh is generally between 0.6 meters and 2.5 meters, and the length can be customized according to user requirements, typically ranging from 2 meters to 10 meters or more.

Application

• Ore classification: In mines, it is extensively used for primary, secondary, and fine screening of ores. It separates ores into different particle size fractions, facilitating subsequent beneficiation processes such as flotation, magnetic separation, and gravity separation.
• Gravel and aggregate production: In quarries, the mesh is vital for screening gravel and aggregates. It ensures that the produced materials meet the specific size requirements for use in construction projects, such as in concrete production, road building, and landscaping.
• Coal processing: In coal mines, woven wire crimp screens are used to separate coal into different grades based on particle size. This is essential for meeting the diverse needs of different industries, such as power generation, metallurgy, and chemical production.
