Working principle of wood sawdust rotary drum dryer
Rotary drum dryer, inside of the rotary drum is tilted slightly, and the cylindrical rotary drum body can
return. Wet materials enter into the upper on one side of the rotary drum, dry materials are collected on the other side of the lower part. Hot air from the feed end or discharge end access to the material and
discharge from the other side of the upper part.
Performance of wood sawdust rotary drum dryer
Rotary drum dryer’s evaporation capacity is generally 80-120kg/m3·h, the capacity will be increased with temperature of hot air increasing, and with the nature of materials’ moisture content changing. Equipment is running smoothly, reliable, non-wearing parts, less malfunction, long service life, it has been widely used in the drying industry.
