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 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 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 |
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
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 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
temperature.
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
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 ordered
as Manganese Steel, high Cr cast iron or
Cr-Mo Alloy Steel.Technical Parameters
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
Hardnesstester,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.
