Low Carbon Cr-Mo Alloy Steel Castings Application For Mine Mill / Ball Mill
1. Hardness difference from surface to center is less than HRC2.
2. The steel liners have higher reliability in AG mills and SAG mills.
3. The Pearlitic Cr-Mo Alloy Steel mill liners are widely used for AG mills, SAG mills, large ball mills.
4. Impact value:AK≥100J.
The additional advantages in cement mills are as follows:
No leakage of slurry |
No repairs during service periods |
Better reliability and stability |
Production Improvement |
Noise reduction |
The general advantages in ball mills are as follows:
Output Increased | 5~20% |
Power Consumption Reduced | 5~20% |
Maintenance Decreased | Above 98% |
The liners are easily installed and existing mills need no modification. | |
Materials 1: Double-Media Quenching Cr-Mo Alloy Steel Series
We specially design the material for ball mill liners in mines, coalfired power plants and cement plants, etc.. With our
special double-media quenching process, the material can not only achieve ideal hardness (HRC48~55) but also
ideal toughness value (AK30~100J). It can completely meet the requirement of liners of large and middle-size ball
mills at home and abroad. The match of Middle Chrome Liners and High Chrome Cast Balls has been the typical model
in coal mills and cement mills. Meanwhile,the material is applicable to the teeth plates, armored plates and hammers of
crushers and excavator bucket teeth.
Materials 2: Pearlitic Cr-Mo Alloy Steel Series
The Pearlitic Chromium-Molybdenum Alloy Steel Liners are widely used in AG Mill,SAG Mill and Ball Mills.
Hardness: HB310-375 (equivalent to HRC33-42)
Impact resistant Value: Ak≥60J (60×10×10mm) in normal ambient temperature.
We can produce pearlitic Cr-Mo steel as per AS2074 Gr. L / 2B.

Depending on the specific working conditions, all wear parts can be ordered as Manganese Steel, high Cr cast
iron or Cr-Mo Alloy Steel.
8. Customer-made Mill Liners
In addition to our patented Boltless Mill Liners, we can produce wear castings as per the request of customers.
So far, we have been the regular suppliers of mill liners for Magotteaux and Foster Wheeler Power Group. Now,
we have supplied steel caps inserted in rubber lifters for SAG mills and AG mills to some mines in Australia and
New Zealand.
For any questions or inquiries, please let us know.
You're welcome to visit our foundries.
