Ball mill for grinding various ores and other materials, are widely used in mineral processing, building materials and chemical industry can be divided into dry ball mill and wet mill. According to ways of discharge can be divided into tabular type and flowing type two.Materials have joined at one end by a cylinder, the cylinder when the ball rotates, friction and ball mill liner between the liner and the cylinder liner itself centrifugal force, the ball along the cylinder liner raised to a certain height, and because of their own gravity thrown down, again and again. The impact of the falling ball mill liner material make it broken, while the relative sliding and rolling mill and ball mill liners and liner ball mill and ball mill between, but also make interposed therebetween materials subjected to grinding, the material with the ball in axial cylindrical body produces impetus gradually moved forward, and continue to impact and grinding and refining, and ultimately achieve the desired fineness is discharged by the other end of the cylinder.
Ball mill liners contain different surface shape of the grinding capacity are not the same, you can choose the thickness of different shapes according to ball mill liners and grinding characteristics of the material. In the ball mill liner protects the device is too important and grinding mill shell accessories. Ball mill liner material requirements are particularly high. Because the ball is coarse position by the impact of the role of the grinding bodies, so that the required materials have sufficient impact toughness after impact, work hardening its surface can become very hard wear.
In recent years, Mill Green areas a lot of effort to ensure that the ball mill and other processing equipment when used in accordance with national environmental standards for the development of China's environmental protection industry utmost efforts
