Alloy Steel Castings Plates For Jaw Crusher With Sandblasted Treat
1. Alloy: 15%Cr.
2. The Jaw Plates are cleaned, sandblasted with a nice surface
without any obvious visual defects that
can avoid the normal working of the castings.
3. Hardness: more than HRC60;
4. Microstructure: Fine Martensite + Carbide + retained
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
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,
coal-fired 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
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 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 ordered as
Manganese Steel,high Cr cast iron or Cr-Mo Alloy Steel.
Our foundry has complete melting, heat treatment and test
equipments,such as mid-frequency
induction electrical furnaces,quenching and tempering furnaces,
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.
