Fly ash dryer is suitable for fly ash, gypsum and titanium gypsum and other industrial dust, sludge drying, which works as follows: Powder or granular ash by the feeding conveyor belt to the feeder, then by feeder fly ash transported to the drying drum, fly ash drying in the drum cloth copy board is turning down, uniformly dispersed with hot air full access, the purpose of drying heat and mass transfer. Fly dried in drum unloading terminal is discharged finished wheat grain dryer by belt feeder machine to dry goods output, complete the drying process. Old vertical dryer: equipment from external combustion furnace, vertical dryer host and environmental protection equipment composition, vertical dryer drum inside lined with firebrick grain dryer, abdominal multiple sets of hopper and sliding materials pots. Its working principle is: material from the delivery device into the upper vertical dryer, by its own gravity hopper through the set, slip material basin decreased sink. Burners produce heat rice grain dryer, after heat exchange through vertical dryer, the environmental protection equipment discharge. Although the collection hopper and slip angle spout material the rate of decline slowed, extending the time the heat exchange material, but the material in the hopper and slide the case of the central discharge spout coast, the wind tunnel is formed with a lot of heat air filtration materials, coupled with continued cooling cylinder burner, thermal efficiency is only about 50%.
