1. Core Composite Accessory Series for Semi-Autogenous Mills

1. Composite Liners for Semi-Autogenous Mills

• Bimetallic composite liner: The matrix is made of tough materials such as high manganese steel, and the working surface is compounded with a high chromium alloy wear-resistant layer, which improves impact resistance and greatly extends the wear life.

• Rubber-metal composite liner: It is formed by compounding a metal skeleton with a high-wear-resistant rubber layer. It has outstanding shock absorption, noise reduction and impact resistance, and is suitable for impact working conditions of large ore blocks.

• Polyurethane composite liner: The metal base is compounded with a wear-resistant polyurethane layer, which is corrosion-resistant and erosion-resistant, and is suitable for wet grinding and slurry environments.

2. Composite Pressing and Positioning Parts

• Composite pressing strip / pressure plate: The metal main body is combined with a wear-resistant rubber buffer layer, which fixes the lining plate more firmly and reduces impact loosening

• Composite wedge block: Adopts a composite material structure, featuring precise positioning, wear resistance and deformation resistance, ensuring the installation stability of the lining plate.

3. Composite Accessories for Inlet and Outlet Systems

• Composite inlet and outlet bushing: Metal matrix composite with wear-resistant rubber/polyurethane layer, resistant to slurry erosion and corrosion, with a service life better than that of pure metal parts

• Composite Liner for Feeding Hopper: The composite structure is impact-resistant, protecting the base of the feeding hopper and reducing damage caused by material impact.

4. Composite Sealing and Buffering Accessories

• Composite sealing ring / retaining ring: Composite structure of rubber and metal, with good sealing effect to prevent slurry leakage and dust from entering the transmission parts

• Buffer composite part: used at the end of the mill and the hollow shaft to absorb shock and buffer, protecting the main machine structure

II. Core Features of the Product

1. Break the limitation of single material. Metal provides strength and support, while rubber/polyurethane/high-chromium alloy offers wear resistance and buffering, integrating multiple performances such as impact resistance, high wear resistance and corrosion resistance.
2. The composite structure can effectively absorb the impact energy of materials and steel balls, reduce the problems of liner cracking, corner breaking and fracture, and is suitable for the heavy-load impact working conditions of semi-autogenous mills.
3. Flexible composite layers such as rubber and polyurethane can significantly reduce the operating noise of the mill, minimize vibration and impact, and protect the mill cylinder and transmission system.
4. Compared with traditional high-manganese steel accessories, the composite structure improves wear resistance by 30%-100%, extends the replacement cycle, and reduces the frequency of shutdowns and overhauls.
5. Manufactured in accordance with the original factory size standards, it perfectly matches the installation interface of the SAG mill, and can directly replace the original metal accessories without modifying the equipment.
6. For working conditions involving ore pulp and water-containing materials, the composite layer has excellent water resistance and corrosion resistance to acid and alkali, and has a wider scope of application.

III. Scope of Application

• Suitable equipment: Various large and medium-sized semi-autogenous mills, autogenous mills, and overflow mills

• Applicable industries: Non-ferrous metal mines, ferrous metal mines, sand and gravel mineral processing, metallurgy, building materials, chemical industry, etc.

• Applicable working conditions: High-impact grinding of large ore blocks, wet grinding slurry conditions, strong abrasion continuous operation, and mining scenarios requiring shock absorption and noise reduction
