Meterials (The diameter of the materials <5 mm) sawdust, rice hull, milled wheat straw, corn stalks and so on
Clarification
if the moist rate is about 12%, it does need to dry the sawdust if the moist rate of wood sawdust is above 12-30%, the drying machine is needed to dry the moisture to 8%-12%.
Working principle:
In the sawdust dryer, high-speed hot air stream sustain raw material in the suspending state, then the material is dried. Since air stream speed is very high, and mateirls suspending in air stream, the heat transfter surface between air and raw mateiral is large, so the heat transfer rate is high.
