The operation characters of coal pulverizing system with intermediate storage bunker for ball mills

as well as factors affecting economic operation of said system have been analysed.Directing against these.a tri-loop automatic control strategy on the basis of combining the fuzzy decoupling with the self-optimization fuzzy sampling PI has been put forward

to coordinately control three outputs of the coal pulverizing system.Application in the field shows that the designed control system can well realize the decoupling control in three loops

being safe and reliable in operation

having remarkable effectiveness of energy-saving.
