The Combined Self-fastened Boltless Ball Mill Liners
The outstanding advantage of our liners is boltless.
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 |
In the recent 20 years, our liners have been widely used in large, medium and small ball mills in
Chinese power generation, mining,cement, chemical engineering and metallurgical industries and
super fine pulverizing equipments. It is the only recommended liner product in the latest standard
of the electric-power industry in China.
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
linersof large and middlesize ball mills at home and abroad. The match of Middle Chrome Liners and
High Chrome
