introduction：summarize： The material is fed into the stirring dryer by the screw conveyor，The hot air enters the dryer from the tangential direction of the feeding end and contacts the crushed material for initial drying，Under the dual action of stirring and air flow，The material moves backward and is continuously raised and crushed by the mixing claw，And exchange heat and mass with hot air。In this part，The material that is crushed to a small enough size dries first and flows away with the air flow，Relatively large material particles have high water content，Stay for a while longer，therefore，Stir dry parts even into them300~500℃Hot wind of，The material temperature will not be high。Behind the mixer dryer，The material is lifted by the double action of sheet and air flow
