Saw dust rotary dryer adopts spiral conveyor and sends the powder particle wet saw dust to the dryer tube continuously. Among the deliver and disperse of high speed hot air current, the water in wet material evaporate, the powdery or graininess dried products is discharged. Saw dust dryer consists of air heater, feeder, flash drying, cyclone separator, and fan.
Saw dust rotary dryer features:
1. It is of great drying strength. As the material is highly dispersed in air current, the whole superficial area of the particle equals to the effective drying area.
2. The drying time is short.
3. The blast dryer is of simple structure, small floor area, and it is easy to construct and maintain.
4. It is of large handling capacity, high heat efficiency. When drying the unbound water, the heat efficiency can reach to 60%.
