The Combined Self-fastened Boltless Ball Mill Liners

The outstanding advantage of our liners is boltless.

The general advantages in ball mills are as follows:

The additional advantages in cement mills are as follows:

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

linersof 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 26Cr. 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 CrusherJaw plates and cheek plates for jaw crushers, blow bars and impact plates for impact crushers,cone liners forgyratory 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.
