After grinding, the pulverized fly ash needs to be classified again in the powder concentrator. The fine ash that meets the requirements is sent to the fine ash silo through the conveying equipment, and the coarse ash is sent back to the ball mill for secondary grinding. The whole system is equipped with a dust collector.
