It is a problem that how to improve the efficiency of the ball mill for general customers, manufacturers have also been working on this problem. However, What are the factors affecting the efficiency of ball mill? Actually, It's the texture of the liners and steel balls. 

 

The liner and steel ball are the main working parts in the normal operation of the ball mill. With the development of the ball mill manufacturer, the type and type of ball mill are also increased, the ball mill is getting bigger and bigger, the quality requirements of the liner and steel ball are also getting higher and higher, and the selection of the ball mill liner and steel ball is becoming more and more important. 

 

1.About the ball mill liner 

The traditional high manganese steel is no longer suitable for ball mill liner. As we all know, high manganese steel liners are prone to creep and extension, surface phase transitions can cause anti-arch deformation, it is impossible to obtain ideal machining hardening in the working condition of the ball mill. The former is the root cause of the leak and the broken bolt, while the latter indicates that the anti-friction properties of the imagination cannot be realized. From a stable and reliable perspective, most of large ball mill, self-grinding mill or semi-self-grinding mill choose to stable austenitic high manganese steel liner.

 

2.About the ball mill steel ball

At present, widely used at home and abroad are the forging of high carbon alloy castings and high carbon low alloy forging or casting, In the production of fire power plant and cement industry, must use high or low chromium cast iron mill balls. But in the wet process of mine industry, high carbon low alloy grinding ball usually be applied. 

 

Between the liner plate and the mill ball, the first choice is the liner In the sandstone production line. It is necessary to ensure that the service life of the liner is above two major repair periods, and try not to maintain it as much as possible. Giving preference to those liner with good reliability and high resistance to wear. 

 

The matching of the liner and the ground ball should be based on the idea of "baseboard", the grinding resistance of the grinding ball mill should be chosen the best on the premise that the service life of the lining is guaranteed by two major repair periods. The hardness of the liners should be greater than the HRc50, the hardness of the alloy of the alloy is greater than that of HRc52, and the hardness of the forging alloy steel grinding ball should be greater than that of HRc55. Generally, it is the best to choose the best abrasion resistance. 

 

Choosing best parts of the equipment so that to guarantee the function well, reduce wear and tear and extend the service life of the ball mill.
