Large Martensitic Cr-Mo Alloy Steel 95 - 107 Hammer Crushers
1. Hardness difference from surface to center is less than HRC2.
2. The Pearlitic Cr-Mo Alloy Steel mill liners are widely used for AG mills, SAG mills, large ball mills.
3. The steel liners have higher reliability in AG mills and SAG
4. Impact value:AK≥100J.
5. Hardness: More Than HRC43.
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 with stand impact from
We possess famous patented product Combined Selffastened (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:
Power Consumption Reduced
The liners are easily installed and existing mills need no
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
High Chrome Cast Balls has been the typical model in coal mills and
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
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.
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.
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
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.
