sawdust rotary dryer introduction
Biomass drying machine is the best choice to dry biomass materials of high moisture content and produce high
quality biomass fuel.
Biomass materials go through dryer can improve biomass fuel efficiency of
5-15% and lower down emission.
Drum dryer plays an important role in drying process of biomass pellet production line.
Application
Biomass drying machine, also called sawdust dryer machine or biomass drum dryer.
Available mainly raw materials: sawdust or grinded wood powder.
Available other powder biomass materials: straw, rice husk, alfalfa, peanut shell, palm nut, coconut shell,cotton seed,
bamboo dust, elephant grass,sugar cane,pulp .etc.

Attractive Advantages
1.Three-pass dryer, longer mixing duration of hot air and material. It is with high drying efficiency,heat utilization ratio
and less space needed.
2. Support of roller ring and retainer wheel are integral cast steel structure, with high strength,stable operation,
anti-abrasion and long service time.
3. Feeding device is separately designed, which is convenient for installation and transportation.The drum of dryer
can be designed to fit the transportation in the containers.
4. Convenient feeding: feeding from middle of dryer by screw conveyor or from the top
based on the different materials.
5. Sealed by flexible and anti-abrasion steel disc at the drum body and feeding &discharge end.It's of long service
time and with easy installation.
6. Lifting plates installed inside the drum makes the material fully mixed with the hot air,
with low residue and high drying efficiency.
7. Reasoable discharge structure that can separate hot air and material efficiently.
8. Thermal insulation set at outer layer of drum can effectively prevent the heat from losing and improve the
utilization efficiency.
9. Three layers drum dryer's floor space is 30% less than single drum dryer with same capacity.
