High Manganese Steel Ball Mill Grate Liners and Wear Plates for Mining Machinery

High Manganese Steel Ball Mill Grate Liners and Wear Plates for Mining Machinery

Product Description
We are a professional manufacturer of high-end castings for the mining industry. Our core capabilities cover High Manganese Steel, High Chrome, Alloy Steel, and Ductile Iron, supplying critical wear components for Ball Mills, Jaw Crushers, and SAG/AG Mills. This series of grate liners is specifically designed for discharging systems, engineered to withstand severe abrasion and impact to extend equipment uptime.

Applications

•      Ball Mill Grate Liners: Essential components at the discharge end, designed to retain grinding media and regulate material outflow to prevent over-grinding .

•      SAG and AG Mill Wear Parts: Heavy-duty castings suitable for high-impact environments in semi-autogenous grinding processes.

•      Mining and Aggregate Plants: Reliable wear protection for continuous, high-throughput operations .

Production and Quality Inspection
We implement a rigorous quality control system to ensure product integrity under high-impact loads. Below is our inspection process with image placement suggestions:

1.      Chemical Composition Analysis and Heat Treatment: We strictly control alloy content (Mn, Cr, C) with S and P below 0.006% . Castings undergo water toughening at 1050-1100C to eliminate carbides and achieve a uniform austenitic structure .

2.      Hardness Testing and 3D Scanning: After heat treatment, we systematically test initial hardness and utilize 3D scanning to verify the complex slot geometries and dimensional curvature against the original CAD design.

3.      Non-Destructive Testing MT and UT: We perform Magnetic Particle Testing (MT) for surface crack detection and Ultrasonic Testing (UT) to identify internal porosity or shrinkage defects .

4.      Dimensional Inspection and Metallographic Analysis: Precision gauges verify slot widths and installation clearances. Metallographic analysis examines the grain structure to confirm no excessive carbide precipitation, ensuring optimal work-hardening capacity .

Support and Services

•      Custom Drawings: We accept customer drawings and offer OEM/ODM services with custom sizes and slot widths .

•      Technical Consultation: Our engineers assist in selecting the ideal material grade (High Mn, High Cr) based on your specific mill conditions and feed characteristics.

•      Traceability: We maintain casting heat number records for full batch traceability.

Packing and Shipping

•       Packing: Standard export wooden pallets or steel crates, secured with straps to prevent movement during transit .

•       Protection: Anti-rust oil treatment and VCI paper wrapping to protect against corrosion during ocean freight .

•       Shipping: Suitable for heavy sea freight; we support FOB, CIF, and DDP terms, ensuring safe delivery to your port .
