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 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 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.
