Analysis of fan mill maintenance method

Fan mill is the main equipment used for direct blowing pulverizing system of lignite burning boiler unit in thermal power plant, and it is also applicable to therequirements of dynamical boiler pulverizing system for chemical industry or paper making. It is a high efficiency pulverizing equipment with the functions of completinggrinding, drying and conveying simultaneously. Fan mill consists of enclosure and high speed beater wheels. Installation and disassembly of beater wheel shall be accomplishedindependently by special overhaul trolly, in this way it is easy to disassemble and install the beater wheel. The analysis is about maintenance and caution of direct-fired fan millpulverizing system in large coal fired power plant.
