The general advantages in ball mills are as follows:
Power Consumption Reduced
The liners are easily installed and existing mills need no
The additional advantages in cement mills are as follows:
No leakage of slurry
No repairs during service periods
Better reliability and stability
Materials 1: Double-Media Quenching Chromium-Molybdenum Alloy Steel
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
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
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 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
as per AS2027, ASTM A532 and BS4844.Customer-made Mill Liners

The Combined Self-fastened Boltless Ball Mill Liners
This product, invented by Mr. Chen Changshun, senior engineer and
the director of the company, is known as “China Best Liner”.
It includes two parts, high wear resistance boltless plates, and
highly expandable riveting plates,
which are self-fastened and strengthened to withstand impact from mill balls.
We possess famous patented product------
Combined Self-fastened (Boltless) Ball Mill Liners, or Called CHINA
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.
