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: 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 2: 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 3 : High Chrome White Iron Series
High Chrome white iron we can produce include 15%Cr, 18%Cr, 20%Cr and 26Cr. 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.Customer-made Mill Liners
In addition to our patented Boltless Mill Liners, we can produce liners as per the request of customers.
So far, we have been the regular suppliers of mill liners for Magotteaux and Foster Wheeler Power Group.
Now, we have supplied steel caps inserted in rubber lifters for SAG mills and AG mills to some mines in Australia and New Zealand. Wear Parts for CrusherJaw plates and cheek plates for jaw crushers, blow bars and impact
plates for impact crushers, cone liners forgy ratory crushers, hammers for hammer crushers and concaves and
mantles for cone crushers.
Depending on the specific working conditions, all wear parts can be ordered as Manganese Steel, high Cr cast iron or Cr-Mo Alloy Steel.

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.
Our foundry has complete melting, heat treatment and test equipments, such as mid-frequency induction electrical furnaces, quenching and tempering furnaces, blast shot, spectrometer, Rockwell and Brinell Hardness tester, impactor, UT tester and metallographic microscope. We achieved the certificate of quality management system ISO 9001:2008. We have been exporting castings to oversea markets, such as Brazil, Australia and South Africa.
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.
