Structure and Benefits of the Sawdust Dryer

Sawdust Dryer is mainly composed of a heating furnace, inlet, rotating cylinder, filtering cylinder, conveying pipe, cooling tube and the outlet.

Working Principle of Sawdust Dryer:

1. The sawdust is fully dried in the rotating cylinder;

2. Sawdust is fully dispersed again before entering into the material conveying pipe, so that the evaporation will be faster;

3. The material is boiling in the tube, the hot air and material will fully contact with each other to complete the drying process.

How to Improve the Efficiency of Fote Sawdust Dryer Machine?

Faced with numerous changes and threats, Fote keeps on the research of how to increase the efficiency of the sawdust dryer and finds some tips.

1>> Replace the spiral conveying blades at the feeding end with 6mm steel triangular stiffened plates. It is to lower the sawdust speed in the high-temperature zone and to make a maximum utilization of the heat. 

2>> Build central X-shaped lifting blades to prolong the residence time of the material and improve the heat transformation;

3>> Change the angle of the feeding tube. With the standard of not to influence the feeding efficiency, lift the blanking cylinder as much as possible. The top of the lifted tube shall not touch the material retaining ring. The part of the tube inside the cylinder shall be not too long and the material falls within the 200mm of the retaining ring. Thus, a material screen is formed and heat transformation is enhanced.
