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-fastenedand 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
5~20%
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 linerproduct 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
double-media quenching process, the material can not only achieve ideal hardness (HRC48~55) but also
