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

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

Product Description

We are a professional manufacturer of high-end castings for the mining and cement industries. 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 grate liner is engineered for severe abrasion and impact in grinding and discharging operations, ensuring extended service life and increased equipment uptime .

Applications

• Ball Mill Grate Liners: Designed to protect the mill shell while controlling the discharge of ground material and retaining grinding media .

• SAG and AG Mill Components: Suitable for high-impact energy environments in semi-autogenous grinding processes .

• Aggregate and Cement Plants: Provides reliable wear protection in heavy-duty continuous operation .

Production and Quality Inspection

We implement a rigorous quality control system to guarantee reliable performance. Please refer to the following inspection images:

1. Chemical Composition Analysis and Heat Treatment: We precisely control the content of Cr, Mn, Mo, and Ni to ensure material consistency. The castings then undergo precise water toughening or quenching heat treatment to achieve an ideal austenitic structure and optimize hardness and toughness 

2. Hardness Testing and 3D Scanning: We systematically perform Rockwell or Brinell hardness tests to guarantee uniform wear resistance. Additionally, 3D scanning is utilized to verify the complex geometric profiles and installation dimensions against the original CAD design 

3. Non-Destructive Testing MT and UT: To ensure internal and external structural integrity, we perform Magnetic Particle Testing (MT) to detect surface cracks and Ultrasonic Testing (UT) to identify internal porosity or shrinkage defects 

4. Dimensional Inspection and Metallographic Analysis: Precision gauges and check fixtures verify slot widths and installation clearances for perfect fit. Metallographic analysis examines the carbide distribution and grain size to confirm an optimal material structure for maximum wear life .

Support and Services

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

• Material Optimization: Our engineers assist in selecting the ideal material (Mn13Cr2, Mn18Cr2, Cr26, etc.) based on your specific working conditions 

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

Packing and Shipping

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

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

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