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.
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.
Materials 1: Double-Media Quenching Chromium-Molybdenum Alloy Steel Series
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 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 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.
