The air is heated to about 180-300 ° C through the heater and enters the flash dryer. The wet material is sent to the screw feeding mechanism by the conveying device, and the screw feeder can be step lessly regulated, and the bottom annular gap is adjusted according to different material properties, so that the wind speed is in an appropriate state. The material enters the drying tower directly through the flash dryer screw feeder, and under the impact and driving of the high-speed airflow, it rapidly disperses and rotates with the airflow to complete the drying process.
