A method for installing the cylinder liner of a tube mill

Abstract

The invention discloses a mounting method for a tube mill shell liner. Bolt holes are formed in a shell; a liner is fixed on the inner side of the shell through bolts, and the gap between the liner and the inner side of the shell is filled with a filling material. Through the mounting method, universality of mill shell liners with different diameters is realized on the premise that the original design requirements of a mill are met, the number of kinds of stored liner dies is reduced, the production cost and fund occupation of a casting factory are lowered, the universality of shell liner spare parts is improved, and production organization and efficiency improvement are facilitated. Besides, through the universal mounting method provided by the invention, the number of kinds of tube mill shell liner dies under similar working conditions can be reduced by more than 50%, the storage quantity of liner dies can be reduced effectively, the production cost and fund occupation of the casting factory are lowered, and production organization and efficiency improvement are facilitated.

Description

technical field [0001] The invention relates to technical fields such as cement, mining, and metallurgy, and in particular to a lining board installation method for improving the versatility of the lining board of a tube mill cylinder. Background technique [0002] At present, cement, mining, metallurgy and other industries use many types of tube mills for grinding preparation. The grinding principle and the lining installation form used in the mill are basically the same, because the production capacity scale and production process organization of each enterprise are different. , and considering different design and manufacturing differences, there are many specifications of tube mills on the market, so there are more types of cylinder liner spare parts corresponding to each tube mill. [0003] According to the original design requirements, the cylinder liners of the tube mill are all wear-resistant castings, and the liners corresponding to each specification need to design...

AI Technical Summary

Problems solved by technology

[0003] According to the original design requirements, the cylinder liners of the tube mill are all wear-resistant castings, and the liners corresponding to each specification need to design and manufacture molds for production, so the manufacturers of liner spare parts will make them according to different cylinder diameters A large number of moulds are reserved, because the installed capacity of some mill liners of some specifications is small, the corresponding mold utilization rate is low, which will occupy production and operation funds, and in the long run will increase the burden on small and medium-sized foundry enterprises
