The Combined Self-fastened Boltless Ball Mill Liners

This product, invented by Mr. Chen Chang- shun, 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

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, 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.

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.

  • Business Description: We specialize in production of wear, heat and corrosion resistant

    castings and the relevant grinding equipments. We were awarded the

    certificate of High New Technology Enterprise issued by Sci tech Bureau,

    Jiangsu Province in 2004.

    We possess famous patented product COMBINED SELF FASTENED (BOLTLESS) BALL MILL LINERS, called "China Best Liner", which was invented under the guidance of the System Engineering Theory of Ball Mills, which was proposed by General Manager, Senior Engineer, Mr. Chen Changshun. The lining plates, without any bolts, are easily installed. The plates are firmly assembled and easily maintained under a low cost. This is an epoch making ball mill liner product in the past 100 years. The reliability and stability of the new plates are much better than those of traditional bolted ones. In the recent 20 years the boltless ball mill liners have been widely used in large, medium and small ball mills in coal fired power plants, mines, cement works, chemical engineering factories and super fine powder grinding plants. It is the only recommended liner product which is allowed to be list into the latest Electrical Power Industry Standard in China (DL/T681 1999). The product was awarded the certificate of High New Technology Product, issued by Sci tech Bureau, Jiangsu Province in 2004.

    Our products involve various kinds of materials, such as low Chrome alloy steel, middle chromium white iron, low chromium cast iron, Ni hard cast iron, high Manganese steel and other heat and corrosion resistant castings. Our foundry has necessary production and heat treatment equipments, such as mid frequency induction electrical furnaces, quenching and tempering furnaces, blast shot. 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.
