Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a structure for preventing the lining plate of a ceramic ball mill from falling off. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder. It is widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass ceramics, for dry or wet grinding of various ores and other grindable materials. Ball mill liners are used to protect the cylinder from direct impact and friction between the grinding media and materials. Different types of liners can also be used to adjust the movement of the grinding media to enhance the pulverizing effect of the grinding media on the materials, thereby improving the grinding efficiency of the mill, increasing output, and reducing metal consumption.

[0003] The ball mill liner anti-detachment structure disclosed in Chinese Utility Model Patent Application Publication CN219745024U, although capable of elastically fixing and supporting the liner and facilitating liner removal while ensuring stability, has drawbacks such as low rotational stability of the liner, easy detachment during operation, inconvenience in liner disassembly and maintenance, and inconvenience in extracting grinding materials from the device.
