Desciption:
 Desulfurization Gypsum Dryer is particularly designed for chemical material drying, such as desulfurization gypsum, dephosphorization gypsum, coal ash, etc. The cylinder is three-layer rotary cylinder which is high efficient and energy-saving.
The material is fed by feeding machine to the inner layer of the rotary cylinder where forward flow drying is realized, the material is repeatedly shoveled and dispersed by the lifting plate to do heat exchange in screw movement forward. Then material moves to another end of the inner layer and enters the middle layer, where counter flow drying is realized, and the material is winnowed repeatedly and makes its way two steps forward and one back. During this period the material can fully absorb the heat given by both the inner and middle revolving cylinder, and at the same time the drying time is extended, which can make the material perfectly dried. The material moves to another end of the middle layer and falls into the out layer, where the material makes its way in form of rectangle multiple chains, and finished drying material moves rapidly and is discharged out of the drum under the action of the heat wind, while the moisture material can not move fast because of deadweight, and is fully dried inside the rectangle lifting plate.
