Alumina wear-resistant ceramic lining bricks can improve the service life of ball mill liners. We analyze it from the following aspects:
1、Working principle of ball mill:
As an important equipment for refining and powdering solid materials, ball mills are widely used in construction, cement, metallurgy, chemical, ceramics, electric power, pharmaceuticals, and defense industries. During operation, material enters the mill evenly through the feeding device, and grinding media of different specifications inside the mill rotate with the ball mill cylinder to produce centrifugal force. The grinding media fall down after reaching a certain height, impacting and grinding the material.
2、Wear mechanism of ball mill:
The main function of ball mill liners is to protect the mill. During rotation, grinding media and materials are brought to a certain height by the liner and then dropped or spilled to grind and crush the material. The liner is subjected to the impact, sliding, and rolling of steel balls and materials during operation, as well as temperature effects. Therefore, the main failure mode of the liner is abrasive wear under low-energy impacts. Under abrasive wear conditions, wear resistance directly affects the service life of components. Therefore, the material and wear level of the liner are important factors that affect the service life of the ball mill liner.
