times of that of high manganese steel liners and twice of that of low Chrome alloy steel liners;
3. Hardness: HRC58 -61;
4. Microstructure: Martensite + Secondary Carbides + Eutectic;
5. International Standard to be applied: AS2027, ASTM A532 and BS4844.
Our main product series are ball mill liners, grinding media. Boltless Ball Mill Liners decrease maintenance of liners
and save the cost of bolts. What's more, our boltless-liner design can exert the maximum quenching
hardness of metal material while the bolted liners design has to scarify the quenching hardness to get toughness because each bolt hole is a source of the thousands of crackings
Patented Anti-wear Product
We possess famous patented product------
Combined Self-fastened (Boltless) Ball Mill Liners, or called CHINA BEST LINER.
In 2012, we registered a new patent about Liner Technology.
In December of 2000, we successfully registered the international patent in Canada.
In 1988 and 1997, we claimed domestic patents for ball mill liners .
The outstanding advantage of our liners is boltless.
The general advantages in cement mills are as follows:
Output Increased | About 5% |
Power Consumption Reduced | 5-20% |
Maintenance Decreased | Above 98% |
Liner Consumption Reduced | 20-80% |
The liners are easily installed and existing mills need no modification. | |
The additional advantages in cement mills are as follows:
No leakage of powder |
No repairs during service periods |
Better reliability and stability |
Production Improvement |
Noise reduction |
So far, we have supplied more than 400 sets of boltless coal mill liners for Chinese Coal-fired Power Plants.
<1> Martensite Cr-Mo Alloy Steel Coal Mill Liners
In the normal working condition, the lifetime of the liners is about 4 to 6 years.
<2> High Cr Coal Mill Liners
In the normal working condition,the service lifetime of the liners is more than 8 years.
In Huaibei Power Plant, our high Cr Coal Mill Liners are used for 14 years without Repairs.
<3> Cr26 Coal Mill Liners
In the normal working condition, the lifetime of the liners is more than 10 years.
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.
