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.
