There are many types of mill liners. In order to have a comprehensive understanding of them, they can be roughly classified according to the parts they use and their materials.
According to the use of different parts of the liner can be divided into: cylinder liner, grinding head liner, grinding door liner, special liner.According to the liner material can be divided into: metal liner, rubber liner, stone or cast stone liner, mixed liner.
The liner is mainly used to protect the barrel from the direct impact and grinding of the abrasive and the material, and different forms of liner can be used to adjust the movement of the abrasive in the barn.
The grinding process of materials is as follows: first, the granularity of the material in the first warehouse is larger, the abrasive body should be mainly impacted, and the grinding body should be thrown down, so the lining board in the grinding bin has higher lifting ability to the grinding body and should have good impact resistance; In order to grind the products to the required fineness, the grinding body should enhance the grinding function in turn, that is, the grinding body needs to produce rolling and sliding, that is, to make the grinding body appear as a drop, Therefore, it is required that the liner have good wear resistance. Because the moving state of the grinding body depends on the rotating speed of the cylinder body of the mill, the grinding process requires that the grinding body in each warehouse take on different motion shape. State, which contradicts the mill cylinder with the same speed. The method to solve this contradiction is to change the motion state of the grinding body by using the linings with different shapes to meet the requirements of the grinding process of the material, thus improving the grinding efficiency, increasing the output and reducing the metal consumption.
