A split grinding bowl of a coal mill

Abstract

The invention discloses a split grinding bowl of a coal grinding mill, which comprises a connecting unit and two or more grinding bowl units, wherein the adjacent grinding bowl units are connected and fixed via the connecting unit. The original grinding bowl with a relatively large diameter is replaced by the split grinding bowl units, and the grinding bowl units are connected and fixed. During disassembly, the split grinding bowl units can be taken directly in and out of the doorframe of a separator body of the coal grinding mill, with no need for dangerous high-altitude operations, so as to facilitate the disassembly of the grinding bowls of the coal grinding mill and reduce the workload and labor intensity of the disassembly.

Description

technical field [0001] The invention relates to the field of a mill bowl structure of a coal mill, in particular to the field of a split mill bowl structure of a coal mill. Background technique [0002] At present, the grinding bowls of domestic coal mills are all integrated grinding bowl structures, especially including the integrated grinding bowl structure with the grinding bowl and the grinding bowl hub. During the assembly process, it is necessary to dismantle all the parts above the grinding bowl in the coal mill from top to bottom. The disassembly and assembly process is a high-altitude operation, the safety factor is not high, and the disassembly and assembly technology is difficult, the disassembly and assembly efficiency is low, and the maintenance workload is high. big. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art and provide a split grinding bowl with simple disassembly steps and less difficu...
