High Abrasion Performance Pearlitic Cr-Mo Alloy Steel Castings Liners


High Abrasion Performance Pearlitic Cr-Mo Alloy Steel Castings Liners


Quick Details

1. The series are designed for high abrasion performance.

2. Hardness: HRC33-43.


Description:


Pearlitic Cr-Mo Alloy Wear Casting Liners

1. Hardness difference from surface to center is less than HRC2.

2. The Pearlitic Cr-Mo Alloy Steel are widely used for AG mill liners,SAG mill liners, large ball mill liners.

3. No bulging parts on grinding surface.

4. Impact value:AK≥60J.

5. Keep dimension of bolt holes precisely and remain no bulging parts along inner surface of holes.

6. Hardness: HRC33-43.


Our main product series are ball mill liners, wear parts for crushers and grinding media. Boltless Ball Mill Liners decrease maintenance of liners and save the cost of bolts. What’s more, our boltless-liner design can exert the maximum quenching hardness of metal material while the bolted-liner design has to scarify the quenching hardness to get better toughness because each bolt hole is a source of thousands of crackings.


Patented Anti-wear Product


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 coal mills are as follows:


Output Increased

About 5%

Power Consumption Reduced

5-20%

Maintenance Decreased

Above 98%

Liner Consumption Reduced

20-80%

The liners are easily installed and existing mills need no modification.


The additional advantages in coal mills are as follows:

No leakage of powder

No repairs during service periods

Better reliability and stability

Production Improvement

Noise reduction


So far, we have supplied more than 400 sets of boltless coal mill liners for Chinese Coal-fired Power Plants.


<1> Martensite Cr-Mo Alloy Steel Coal Mill Liners

In the normal working condition, the lifetime of the liners is about 4 to 6 years.


<2> High Cr Coal Mill Liners

In the normal working condition,the service lifetime of the liners is more than 8 years.

In Huaibei Power Plant, our high Cr Coal Mill Liners are used for 14 years without Repairs.


<3> Cr26 Coal Mill Liners

In the normal working condition, the lifetime of the liners is more than 10 years.


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.
