    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


    Power Consumption Reduced


    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.

    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 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 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.
