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.
