In the context of the rapid development of new energy and the deep peak shaving and long-term flexible operation of thermal power units

the co-firing of economic coal types in power plants becomes a major trend.The problem of insufficient output of the pulverizing system becomes one of the main issues in power plant operation.To solve the problem of insufficient output of medium speed coal mills

taking a ZGM95G coal mill in a power plant as the research object

it adopts a research method combining theoretical research and engineering practice to analyze the efficiency improvement and consumption reduction scheme of coal mills.It can be known from the research results that it increases the grinding output by raising the rotational speed of the grinding disc

and reduces the resistance by replacing the dynamic and static ring devices.It further reduces the wear of the casing by increasing the flow guide distance.This research can provide a reference for the efficiency improvement and consumption reduction of coal mills.
