The ball mill is a beneficiation equipment that re-grinds the ball mill after the crushing operation of the mine selection plant. In addition to the concentrating plant, it can also be applied to the grinding of cement, silicon hydrochloric acid products, new building materials, refractory materials and glass ceramic materials. Among them, the ball mill liner is one of its main accessories. Below we briefly introduce the main function of the ball mill liner and its materials.

The role of the ball mill
1. First, the role of the ball mill liner is to protect the barrel of the ball mill so that the barrel of the ball mill is not directly impacted and rubbed by the grinding media and materials.
2. Secondly, the ball mill liner has many different forms, which can be used to adjust the movement state of the grinding medium in the cylinder to enhance the grinding effect of the grinding medium on the material and improve the grinding efficiency.

Ball mill liner material and application
Ball mill liners are mainly made of high manganese steel, alloy steel, hard steel, chrome steel, alloy cast iron, magnetic liner, rubber liner and so on.
However, the high manganese steel liner is now used less, although it has sufficient impact toughness, the surface is cold hardened and harder to wear when subjected to a certain impact, but his processing technology is very demanding and expensive. In addition, high-manganese steel linings are prone to creep and extension, surface phase transformations can cause rib deformation, and can not achieve idealized work hardening.
Now the high-manganese steel lining has been gradually replaced by alloy steel lining and wear-resistant rubber lining. The alloy steel lining is wear-resistant, impact-resistant and reasonable alloying element formula, which makes the lining board have good physical and chemical properties and the service life is More than twice as high as manganese steel.
