Chromium Molybdenum Steel Concaves Of Ball Mill Lining Packed in Pallets
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 mills.
4. Impact value:AK≥100J.
5. Hardness: More Than HRC43.
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. | |
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 |
Materials 1: Double-Media Quenching Chromium-Molybdenum 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 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 temperature.
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.
