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
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 double-media 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 middle-size 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.
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
Depending on the specific working conditions,all wear parts can be
ordered as Manganese Steel,high Cr cast iron or Cr-Mo Alloy Steel.
