XSG series rotary flash dryer

Working principle

The hot air tangent enters the bottom of the dryer, forming a strong rotating wind field driven by the mixer. The paste like material enters the dryer through a spiral feeder. Under the strong action of high-speed rotating stirring paddles, the material is dispersed under impact, friction, and shear forces. The block like material is quickly crushed, fully in contact with hot air, heated, and dried. The dehydrated dry material rises with the hot airflow, and the grading ring intercepts the large particles. The small particles are discharged from the center of the ring outside the dryer and recycled by the cyclone separator and dust collector. The partially dried or large materials are thrown towards the wall by centrifugal force, and then fall back to the bottom for crushing and drying.

Performance characteristics

The organic combination of rotational flow, fluidization, spouting, and crushing classification technologies. Compact equipment, small size, high production efficiency, continuous production, achieving "small equipment, large production". High drying intensity, low energy consumption, and high thermal efficiency. The material has a short retention time and good finished product quality, making it suitable for drying heat-sensitive materials. ◎ Negative pressure or micro negative pressure operation, good airtightness, high efficiency, and elimination of environmental pollution.
