High Manganese Steel Ball Mill Liners Customized Wear Resistant Casting Parts for Mining Industry

Our company specializes in manufacturing high-end castings made from multiple materials including high manganese steel, high chromium alloy, alloy steel, and ductile iron. Our core products cover mining machinery parts such as ball mill liners, jaw crusher parts, and autogenous or semi-autogenous mill liners. These castings are designed to withstand high impact and high wear conditions. They offer excellent surface hardness and internal toughness.

The ball mill liner serves as a protective armour installed on the inner wall of the mill cylinder. It directly bears the impact and grinding from grinding media and materials. This protects the expensive mill shell from wear. By optimizing the movement trajectory of the grinding media, it significantly improves grinding efficiency. Our liners are custom manufactured according to specific working conditions in mining, cement, power, chemical, and engineering machinery industries.

The ball mill liners are widely used in the coarse and medium-fine grinding of metallic ores. They are suitable for high-hardness bulk ores such as copper, gold, and iron ore. They are also extensively applied in mineral processing, building materials, cement, power plants, and chemical industries. Whether for autogenous mills, semi-autogenous mills, or ball mills with different discharge methods like overflow type and grate type, our wear-resistant castings provide reliable performance under severe impact and abrasion.

The manufacturing process follows a strict workflow. This includes process preparation, sand mixing, molding and core making, box closing, melting, pouring, shakeout and cleaning, and heat treatment. We utilize advanced production lines including ceramic bonded resin sand and lost foam vacuum casting.

To ensure the highest quality, we implement comprehensive inspections.

•    Heat treatment is conducted to eliminate internal stress and improve mechanical properties.
•    Hardness testing verifies the wear resistance index of the casting surface.
•    3D scanning is used to check dimensional accuracy and complex geometries.
•    MT magnetic particle testing detects surface and subsurface cracks.
•    UT ultrasonic testing identifies deep internal defects such as porosity, slag inclusion, and shrinkage cavity.
•    Chemical composition detection ensures the material meets standard requirements.
•    Metallographic analysis examines the microstructure to confirm the desired matrix structure.
•    Dimensional inspection using calipers, micrometers, and coordinate measuring machines guarantees that critical installation interfaces and bolt hole spacing meet drawing tolerances.
•    Every product undergoes bolt trial assembly to ensure smooth installation.

We provide customized production based on specific working conditions and customer requirements. Our experienced technical team offers professional support for material selection, process design, and product optimization. We maintain a complete quality control system with ISO 9001, ISO 14001, and ISO 45001 certifications. Batch traceability archives are established to continuously track product performance and customer feedback. We also offer third-party inspection coordination and provide Chinese and English versions of test reports to meet export requirements.

Products are carefully packed to prevent damage during transportation. We use sturdy wooden boxes, pallets, and protective wrapping such as waterproof tarps to ensure the castings remain in good condition. Each package is labeled with clear information including purchase order number, destination, description, quantity, weight, and dimensions. We support various shipping methods including sea, land, and air freight. This ensures timely delivery to destinations worldwide. Our professional logistics team handles the entire process from factory loading to final arrival, providing a smooth and efficient shipping experience.
