Shell structure of grinding roller of roll mill

Abstract

The invention provides a shell structure of a grinding roller of a roll mill. The shell structure of the grinding roller of the roll mill comprises a shell body, wherein end socket mounting openings are formed in the left side and the right side of the shell body; an end socket of the grinding roller is mounted on each end socket mounting opening; a pressure shaft mounting part is fixedly mounted at the bottom of the end socket of the grinding roller; end socket fixing parts protrude the outer sides of the end sockets of the grinding roller; thread through holes are formed in the end socket fixing parts; thread holes are screwed at the corresponding positions of protruding parts on the other sides of the opening parts of the end socket mounting openings in the left side and the right side of the shell body; and the end sockets of the grinding roller pass through the thread through holes in the end socket fixing parts through bolts, and lock the thread holes in protruding parts on the other sides of the opening parts of the end socket mounting openings. According to the shell structure of the grinding roller of the roll mill, provided by the invention, the shell of the roll mill is in a split structure, so that the anti-vibration function of the entire shell is improved; noises generated in the working process of the roll mill are reduced; and the strength of the shell is improved. Meanwhile, the mill has a good sealing property in the process of milling inflammable and explosive substances, such as coal powder, so that the anti-pressure function and the anti-explosion function can be improved. The entire shell structure is simple, and is convenient to maintain, mount and dismount.

Description

technical field [0001] The invention relates to material grinding equipment, in particular to a roller mill used for grinding various materials in metal ore, non-metallic ore, energy, new materials and other industries, especially a roller mill shell that can be strengthened Hermetic structure. Background technique [0002] With the continuous development of human economic activities, the four aspects of food, clothing, housing and transportation, as the basic material conditions for human survival, have been further improved with the continuous development of science and technology. People not only need to eat enough, but also It is also necessary to eat well and eat healthy; in terms of housing, the basic requirements for shelter from wind and rain have become solid, safe and comfortable; clothing is also increasingly pursued to be colorful, and to show everyone's personality , and the main progress of walking is reflected in the means of transportation. People have devel...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the disadvantages of existing roller mills that the shell structure of the roller installation part is an integral structure, the ability of anti-explosion, anti-shock and noise reduction is relatively poor, and the structure is complex and inconvenient for maintenance and installation. The present invention provides a The shell structure of the installation part of the roller mill can be easily combined and installed, which is convenient for maintenance. The strength of the whole structure is greatly improved, which greatly improves the anti-compression, explosion-proof and anti-vibration capabilities, and reduces the impact of noise on the environment and production insecurity
