High Manganese Steel Mill Lifter Bars Custom Wear Resistant Casting Spare Parts for Ball Mill SAG Mill Mining

High Manganese Steel Mill Lifter Bars Custom Wear Resistant Casting Spare Parts for Ball Mill SAG Mill Mining

Product Description

Our company specializes in manufacturing high end castings of multiple materials including high manganese steel, high chromium alloy, alloy steel and ductile iron. Our core products cover mining machinery spare parts such as ball mill liners, jaw crusher components, autogenous and semi autogenous mill liners.

Mill lifter bars are key wear resistant components mounted on the inner shell of ball mills and semi autogenous mills. The raised lifter structure lifts and releases grinding media and raw ores as the mill rotates, effectively improving grinding performance. These castings are designed to withstand heavy impact and severe abrasion. We can custom manufacture lifter bars according to practical working conditions and customer drawings for mining, cement, power, chemical and engineering machinery industries.

Applications

Our mill lifter bars are widely used in coarse and medium fine grinding of metallic ores. They fit for high hardness bulk ores such as copper ore, gold ore and iron ore. These products are extensively applied in mineral processing, building materials, cement plants, power plants and chemical industries.

Our wear resistant mill castings provide stable and reliable performance under heavy impact and abrasion scenarios. They are compatible with autogenous mills, semi autogenous mills, overflow type ball mills and grate type ball mills.

Production and Quality Inspection

The complete manufacturing procedure includes process preparation, sand mixing, moulding and core making, box closing, melting, pouring, shakeout and cleaning, and heat treatment. We operate advanced production lines for ceramic bonded resin sand casting and lost foam vacuum casting.

Comprehensive inspection is carried out for every production batch. Heat treatment is performed to eliminate internal stress and enhance mechanical properties. Hardness testing verifies surface wear resistance of castings. 3D scanning is adopted to check dimensional accuracy and complex geometric profiles. MT magnetic particle testing detects surface and subsurface cracks. UT ultrasonic testing identifies deep internal defects including porosity, slag inclusion and shrinkage cavity. Chemical composition testing guarantees the material conforms to standard requirements. Metallographic analysis examines microstructure to confirm qualified matrix structure. Dimensional inspection with calipers, micrometers and coordinate measuring machines ensures critical mounting interfaces and bolt hole spacing meet drawing tolerances. Each finished product will go through bolt trial assembly to ensure smooth site installation.

Support and Services

We offer customized production according to specific working conditions and customer requirements. Our experienced technical team provides professional support covering material selection, process design and product optimization. We maintain a complete quality control system certified by ISO 9001, ISO 14001 and ISO 45001. Batch traceability files are kept to track product performance and customer feedback continuously. We can arrange third party inspection service and supply test reports in both Chinese and English versions to satisfy export demands.

Packing and Shipping

Goods are carefully packed to prevent damage during transportation. We use solid wooden cases, pallets and waterproof protective wrapping to keep castings intact. Each package is marked with clear information including purchase order number, destination, item description, quantity, weight and dimensions. Multiple shipping modes including sea freight, land freight and air freight are supported to realize on time delivery to destinations all over the world. Our professional logistics team takes charge of the whole process from factory loading to goods arrival to deliver stable and efficient shipping service.
