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

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

1. Company Overview

We specialize in manufacturing high‑end castings made from multiple materials, including high manganese steel, high chromium alloy, alloy steel, and ductile iron. Our core products include: ‑ Ball mill liners ‑ Jaw crusher components ‑ Autogenous (AG) and semi‑autogenous (SAG) mill liners

Our products serve the mining machinery spare parts market and are engineered for heavy‑impact and severe‑wear working conditions.

2. Core Product: Ball Mill Liners

Ball mill liners act as protective armour installed on the inner wall of the mill cylinder. They directly bear the impact and grinding force from grinding media and raw materials, protecting the expensive mill shell from wear damage. By optimizing the movement trajectory of grinding media, the liners significantly improve overall grinding efficiency.

3. Applications

Our ball mill liners are widely used for coarse and medium‑fine grinding of metallic ores, especially high‑hardness bulk ores:

•     Copper ore
•     Gold ore
•     Iron ore

Industries Served:

•    Mineral processing
•    Building materials
•    Cement plants
•    Power plants
•    Chemical industry

Compatible Equipment:

•    Autogenous (AG) mills
•    Semi‑autogenous (SAG) mills
•    Overflow type ball mills
•    Grate type ball mills

Our wear‑resistant castings deliver reliable performance against impact and abrasion across different types of grinding equipment.

4. Production and Quality Inspection

Production Workflow Process preparation → Sand mixing → Moulding and core making → Box closing → Melting → Pouring → Shakeout and cleaning → Heat treatment

Advanced Production Lines

•    Ceramic bonded resin sand casting
•    Lost foam vacuum casting

Full‑Range Quality Inspection Full‑range quality inspections are implemented for each batch:

1.    Heat treatment: Eliminates internal stress and improves mechanical properties
2.    Hardness testing: Verifies surface wear‑resistance performance
3.    3D scanning: Checks dimensional accuracy and complex geometric profiles
4.    MT magnetic particle testing: Detects surface and subsurface cracks
5.    UT ultrasonic testing: Identifies deep internal defects such as porosity, slag inclusion, and shrinkage cavity
6.    Chemical composition testing: Ensures raw material meets standard requirements
7.    Metallographic analysis: Examines microstructure to confirm qualified matrix structure
8.    Dimensional inspection: Calipers, micrometers, and CMMs ensure critical mounting interfaces and bolt hole spacing comply with drawing tolerances
9.    Bolt trial assembly: Every finished product passes this test to guarantee smooth field installation
