Mn13 Mn13Cr2 High Manganese Steel Ball Mill Liners

Product Overview

Qirun manufactures Mn13 and Mn13Cr2 high manganese steel ball mill liners for mining, cement production, and mineral processing applications. These wear-resistant castings protect the internal surfaces of ball mills from grinding media impact and abrasive material contact.

High manganese steel offers a combination of impact toughness and work-hardening capability. Under suitable operating conditions, repeated impacts harden the liner surface while the underlying material retains its toughness.

Our ball mill liners can be manufactured according to customer drawings, mill dimensions, and operating requirements. We provide casting and machining support for replacement liners, custom wear parts, and grinding mill maintenance projects.

Technical Specifications

Final specifications, component availability, dimensions, and inspection requirements are confirmed according to the customer's technical drawings and purchase requirements.

Key Features of Mn13 and Mn13Cr2 Ball Mill Liners

1. High Impact Toughness

High manganese steel is suitable for grinding environments where mill liners experience repeated impact from grinding balls and ore.

Its tough austenitic structure helps absorb impact energy and reduce the risk of brittle fracture under appropriate operating conditions.

2. Work-Hardening Wear Resistance

Mn13 and Mn13Cr2 manganese steels can develop increased surface hardness when subjected to sufficient repeated impact.

This work-hardening behavior helps the liners resist impact-related wear while maintaining a relatively tough core.

Actual wear performance depends on impact intensity, ore abrasiveness, liner profile, and mill operating conditions.

3. Protection for Ball Mill Shells

Ball mill liners form a protective barrier between the mill shell and the grinding media.

They help reduce direct impact and abrasive contact with the mill body, protecting structural components during continuous grinding operations.

4. Custom Liner Profiles

Different grinding applications require different liner geometries.

Qirun supports custom casting based on mill design, replacement part drawings, and operating requirements.

Liner profiles, mounting arrangements, and component dimensions can be reviewed to match existing equipment.

5. Casting and Machining Support

Our manufacturing capabilities include sand casting and lost foam casting for industrial wear-resistant components.

Casting dimensions, mounting surfaces, and machining requirements can be specified according to customer drawings to support replacement and installation.

Mn13 vs. Mn13Cr2 Ball Mill Liners

Both Mn13 and Mn13Cr2 belong to the high manganese steel family and are commonly considered for impact-resistant wear components.

The appropriate liner material should be selected according to the grinding process rather than material grade alone. Qirun can review customer operating conditions and drawings before production.

Custom Ball Mill Liner Manufacturing

Qirun provides OEM and custom casting services for manganese steel ball mill liners.

Customers can submit technical drawings, existing part dimensions, or replacement liner specifications for manufacturing assessment.

Our customization service can cover:

• Mn13 and Mn13Cr2 material selection

• Custom liner dimensions and thicknesses

• Liner surface profiles and mounting configurations

• Replacement castings based on technical drawings

• Machining of specified installation surfaces

• Casting inspection and export packaging
