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.
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
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
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
(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
We can produce pearlitic Cr-Mo steel as per AS2074 Gr. L / 2B.
We have been producing Cr-Mo Alloy Steel Liners for 10.37 x 5.49m
and 36' SAG Mills for Metso.
Materials 3 : High Chrome White Iron Series
High Chrome white iron we can produce include 15%Cr, 18%Cr, 20%Cr
and 26%Cr. 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 Crusher
Jaw plates and cheek plates for jaw crushers, blow bars and impact
plates for impact crushers,
cone liners for gyratory crushers, hammers for hammer crushers and concaves and mantles for
cone crushers.Depending on the specific working conditions, all wear parts can be
Manganese Steel, high Cr cast iron or Cr-Mo Alloy Steel.
Our foundry has complete melting, heat treatment and test
equipments, such as midfrequency 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 9001:2000. We have been exporting castings to oversea markets,such as Brazil, Australia and South Africa.
