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 doublemedia 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 middlesize 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
