Mill Liners

WALKSON, as one of the reliable mill liners manufacturers, can provide a wide range of wear resistant products for mineral processing industry, such as rod mill liners, grinding mill liners, ball mill shell liners and rubber mill liners; our main products include:

SAG mill liner
AG mill liner
Chute line
Hammer
Shoe hammer of VSI Crusher

The material of these types of the rod mill liner we can provide are Cr-Mo steel for CrMo mill liner, high chrome white iron, high manganese steel and Metal ceramic composite material.

AS2027 / ASTM A532 Standard High Chrome White Iron Liners

Material Type	Hardness (HBW)	Primary Application	Key Feature
Cr-Mo Steel	350-402	SAG/AG Mill Shells	High impact toughness & crack resistance
High Chrome White Iron	≥621	Fine Grinding Mills	Extreme abrasion resistance
MMC (Metal Matrix Composite)	Up to 2x Life	Extreme Wear Environments	Ceramic-embedded for maximum durability

Typical Cr-Mo steel as below, the final hardness is between 350-402 HBW

C	Si	Mn	S	P	Cr	Ni	Mo	Cu	Al
0.75-0.85	0.3-0.8	0.8-1.1	≤0.03	≤0.03	2.0-2.5	≤0.6	0.26-0.36	≤0.3	≤0.03

Typical High Chrome white iron as below, the final hardness is ≥621 HBW

C	Si	Mn	S	P	Cr	Ni	Mo	Cu
2.45-2.85	0.3-0.8	0.8-1.3	≤0.03	≤0.03	22.0-25.0	≤0.70	0.7-0.86	0.90-1.10

Besides normal mill liner and mill relining, WALKSON can also supply metal ceramic composite product.

High-manganese steel substrate and ceramic for manganese liners, namely, the base material of the cone and mantle is high Mn steel, while the cast ceramic matrix embedded with high wear resistance shaped ribs, increase the wear resistance ability while maintaining the original impact resistance of high manganese steel.

Under the same service conditions, the MMC manganese cone's life is 2 times of the normal one. The MMC manganese hammer's life is up to 3 times than the normal manganese hammer.

Following is the comparation test we have done on the machine GP300 about the MMC manganese cone's performance:

Mineral	Particle size	Moh’s hardness	MCC Mn cone life	Normal Mn Cone
Iron ore	50-300mm	6.5	900 Hours	440 Hours

Following is the comparation test we have done on the machine ZGM95G about the MMC roller performance:

Mineral	Particle size	HIG	MCC roller	Normal roller
4500 Kcal/Kg Coal	30-50mm	60	12000-20000 Hours	6000-8000 Hours

Why Choose WALKSON Mill Liners

WALKSON choose High Cr cast iron(or Martensite steel) base ceramic composite materials, which is the liner basement with High Cr cast iron(or Martensite steel), it has better elongation, thus has completely safety of resistance to fracture and embed high wear resistance of ceramic reinforcement into the basement, to get great improvement wear resistance. The life of the ceramic composite liner, compared with common High Cr liner, the product life can be doubled. WALKSON understands the strict safety and quality protocols of the Australian mining industry. Our quality management system ensures full traceability from raw material to the final AS2027-compliant liner delivered to your site.
