Introduction of sawdust rotary dryer (wood chips dryer)
Sawdust rotary dryer or wood chips dryer is widely used to dry humidity granularity materials in the biomass industries. It is an important part of the pellet plant, and the quality of the material has an impact on pelletizing with pellet mill. Sawdust and wood chips should be dried to5-10% water content to meet the demands for pelletizer. It is different from the sawdust flash dryer.

The Principle of sawdust dryer :
The appearance of the drum is the same as that of the general roraty drum dryer, but the interior is made of three straight cylinder sets with different diameters, forming a three-ring roller, all surfaces in contact with the material are equipped with a copy plate. The three-layer rollers are fixed to each other in the radial direction to rotate at the same number of revolutions.
The direction of the material is: wet material from the inner tube into, from the end of the re-entry into the middle tube, after the middle tube into the outer tube, the end of the outer tube discharge.
