Product Overview
Our carbon steel ball mill liners are precision-crafted using investment casting technology to protect grinding mills and optimize performance in mining, cement, and mineral processing operations. Designed from high-grade carbon steel (AISI 1045/1050), these liners withstand relentless impact and wear, ensuring extended equipment lifespan and reduced downtime.

Customer Benefits |
|
Extreme Wear Resistance |
Customized high-carbon steel (0.8-1.2% C) + vanadium-titanium microalloying, achieving a hardness of HRC 55-60 |
lifespan 2-3 times that of ordinary manganese steel liners |
|
Impact-resistant structure |
Silica sol casting achieves one-piece curved reinforcement ribs, eliminating weld weaknesses and delivering an impact toughness of ≥35 J/cm². |
Resists steel ball impact and eliminates breakage. |
|
Precise mounting and matching |
Mold shell accuracy of ±0.3mm/m, with >98% fit between the liner back curvature and the cylinder (supported by a three-dimensional coordinate measurement report). |
Installation time is reduced by 40%; no shim adjustments are required. |
|
Optimized grinding efficiency |
Scientifically designed lifting plate waveforms/lifting bar angles increase material flow rate by 15% (based on DEM simulation). |
Energy consumption per ton is reduced by 8-12%. |
Key Features
- Casting Process: A two-layer silica sol shell ensures liner profile accuracy, with a surface finish of Ra ≤ 3.2μm (reducing material adhesion).
- Material Science: A unique multi-stage heat treatment process (quenching + double tempering) achieves a hardness gradient of less than 3HRC, preventing stress cracking.
- Quality Certification: Conforms to ASTM A532 Class III wear resistance standards, and a full impact, metallographic, and hardness test report is provided for each batch.

Applications
Mining: Grinding copper, gold, iron ore, and other minerals.
Cement Plants: Clinker and raw material grinding mills.
Chemical Processing: Ball mills for ceramics, pigments, and fertilizers.
Power Generation: Coal pulverizing mills in thermal plants.
Our Solutions:
- Gold Ore Wet Grinding System: Hard chrome-plated edge guards + deep carburizing for 14 months of corrosion resistance and wear life.
- Cement Clinker Grinding: Gradient hardness design (HRC60 surface/HRC35 core) for thermal crack resistance.
- Copper Ore Coarse Grinding Mill: Thickened impact zone + buffer grooves reduce breakage by 90%.
Why Choose Our Ball Mill Liners?
- Wear-resistant layer thickness ≥15mm: Vanadium-titanium carbides block wear paths, crushing 80,000 tons more ore than stamped liners.
- Zero bolt hole fracture: Bionic ribs distribute stress, reducing bolt failure rate by 97% (measured data).
- 30-day delivery of custom parts: A library of over 200 molds and a flexible production line ensure industry-leading response times for urgent orders.
