Materials 1: Double-Media Quenching Cr-Mo 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 Cr-Mo 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 specially design the material for cement mill liners ,Which includes boltless liners,shell liners, grate plates ,end liners etc..

The material can not only achieve ideal hardness (more than HRC48) but also ideal toughness value (AK30~100J).

The liners are more reliable and safer than normal liners, it also can save the cost.We can produce cement mill liners as per the drawings of customers.

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.

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.

Summarization

High Cr white iron material possess a combination of superior abrasion resistance and a reasonable degree of toughness. The high Cr castings have longer service life than the other material,such as high Mn steel and Cr-Mo alloy steel.And now it is widely used in the working condition of high wear and low impact,such as dry grinding process,coal mills,cement mills due to its excellent performance.

Test facilities include Spectrometer for chemical analysis, HRC table hardness tester, HBN table hardness tester, two portable hardness testers, impactor and universal material testing machine for inspection of mechanical properties, matrix microscope for metallographic examination, ultrasonic tester for ultrasonic inspection and magnetic particle tester for magnetic testing.

These facilities are used to ensure the consistent quality of products. We achieved the certificate of quality management system ISO 9001:2000. Our current capacity of finished castings is 4500 tons / year. We have a good credit of delivery of products in accordance with the contracts.
