1. Hardness difference from surface to center is less than HRC2.
2. The Pearlitic Cr-Mo Alloy Steel mill liners are widely used for AG mills,SAG mills,large ball mills.
3. The steel liners have higher reliability in AG mills and SAG
4. Impact value:AK≥100J.
5. Hardness: More than HRC43.
The general advantages in ball mills are as follows:
|Power Consumption Reduced||5~20%|
|Maintenance Decreased||Above 98%|
|The liners are easily installed and existing mills need no
The additional advantages in cement mills are as follows:
|No leakage of slurry|
|No repairs during service periods|
|Better reliability and stability|
Materials 1: Double-Media Quenching Chromium-Molybdenum Alloy Steel
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 Chromium-Molybdenum 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
We can produce pearlitic Cr-Mo steel as per AS2074 Gr. L / 2B.
Materials 3 : High Chrome White Iron Series
High Chrome white iron we can produce include 15%Cr, 18%Cr, 20%Cr
and 26%Cr. Under same working condition, the wear performance of
High Chrome mill liners is four times of that of high manganese
steel liners and twice of that of low Chrome alloy steel
liners.Meanwhile, we can produce high Chrome castings as per
AS2027, ASTM A532 and BS4844.
