Mill and Scrubber Linings

The Mill and Scrubber Linings a huge role in the cement industry now,it is very helpful for us to improve work efficiency and skill level.
1. Alloy: 15%Cr.
2. The Mill and Scrubber Linings are cleaned, sandblasted with a nice surface without any obvious visual defects that can avoid the normal working of the castings.
3. Hardness: more than HRC60;

4. Microstructure: Fine Martensite + Carbide + retained Austenite(≤6%)

The Combined Self-fastened Boltless Ni Hard Liners

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.

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 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.

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.

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 Now, we have supplied steel caps inserted in rubber lifters for SAG mills and AG mills to some mines in Australia and New Zealand.
