JCH-TIKTOP focuses on the R&D and production of wear-resistant parts for mining grinding equipment. In view to the working condition characteristics of semi-autogenous mills such as high impact, strong abrasion and continuous heavy load, it specializes in the R&D and manufacturing of composite parts for semi-autogenous mills. The products integrate the advantages of multiple materials and adopt an integrated composite molding process, which combines the high strength of metal with the high elasticity and high wear resistance of non-metallic materials. They effectively solve the problems of traditional single-material parts such as easy fracture, fast wear and high noise. Widely applicable to the matching of semi-autogenous mills in fields such as metal mines, concentrators, building materials and chemical industries, the products can greatly extend the service life of parts and reduce the operation and maintenance costs of equipment.
1. Core Composite Accessory Series for Semi-Autogenous Mills
The composite accessories adopt composite structures of different materials to achieve multiple effects of wear resistance, impact resistance, shock absorption and noise reduction. They are upgraded supporting accessories for large-scale semi-autogenous mills, and our main products include:
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
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.
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.
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.
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.
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.
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.
