Abstract

The invention provides a roller skin of a high-pressure roller mill. The roller skin comprises a main shaft and a roller, and the roller is arranged outside the main shaft in a sleeving mode. The device further comprises a roller skin assembly and a pressing ring, the roller skin assembly comprises a plug welding roller skin and a roller skin matrix, the two sides of the roller skin matrix are respectively connected with the roller and the plug welding roller skin. A plurality of plug welding holes used for conducting plug welding treatment on the plug welding roller skin and the roller skin matrix are evenly formed in the plug welding roller skin at intervals, the pressing ring is movably connected with the roller skin matrix, and the main shaft, the roller, the roller skin matrix, the pressing ring and the plug welding roller skin are sequentially and coaxially arranged from inside to outside. The problems that in the structure of the prior art, the roller skin is of an integrated structure, and a large amount of disassembly work needs to be carried out on inspection, maintenance or replacement of the structural roller skin are solved.

Description

technical field [0001] The invention relates to the technical field of mining machinery manufacturing, in particular to a roller skin of a high-pressure roller mill. Background technique [0002] High-pressure roller mill is a common equipment in the field of stone and mineral processing. One of its implementation modes is quasi-static crushing, and its second implementation mode is to crush materials in layers. At present, the roller skins of high-pressure roller mills are usually vulnerable parts. Due to poor working conditions and severe wear, the replacement and maintenance frequency of roller skins of high-pressure roller mills is relatively high. The published patent name is "Detachable Roller Skin Unit and High-Pressure Roller Grinder Quickly Dismountable Wear-Resistant Roll System Structure", the Chinese utility model patent with publication number CN204911617U, but the integrated roller skin disclosed in this patent document structure, the roller skin will be worn ...
