Installation structure of grinding roller casing of roller type grinder

Abstract

The invention discloses an installation structure of a grinding roller casing of a roller type grinder. The installation structure comprises a casing body, wherein seal head installation openings are installed on the left side and the right side of the casing body, a grinding roller seal heads are mounted on the seal head installation openings, and a pressure shaft installation part is fixedly mounted at the bottom of each grinding roller seal head; and the installation structure is characterized in that the outer edges of grinding roller seal heads are protruded to form seal head fixing parts which are provided with threaded via holes, threaded holes are formed in the position corresponding to the lateral projection parts of the opening parts of the seal head installation openings on the left and the right sides of the casing body in a tapping manner, and the grinding roller seal heads penetrate through the threaded via holes in the seal head fixing parts through bolts to be locked in the threaded holes in the lateral projection parts of the opening parts of the seal head installation openings. According to the invention, the casing body of the roller type grinder is manufactured to be split, so that the shock resisting function of the whole casing body is increased, the noise during the operation of the roller type grinder is reduced, and the strength of the casing body is enhanced; simultaneously when the grinder is used for grinding inflammable and explosive articles such as coal powder and the like, the excellent sealing property can be guaranteed, and the compression resistance and explosion proofing functions are enhanced; and the whole casing structure is simple, and 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.

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
