Three Layers Sawdust Drum Dryer

< Drum Dryer Introduction >
1. Drum dryer is the a better choice to dry biomass materials of high moisture content and produce high quality

    biomass fuel.

2. Biomass materials go through dryer can improve biomass fuel efficiency of 5-15% and lower down emission.

3. Drum dryer plays an important role in drying process of  
biomass pellet production line.

< Application >

Three layers sawdust drum dryer, also called sawdust dryer machine.

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

 bamboo dust, elephant grass,sugar cane,pulp .etc. 


< Basic Features >

  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 upper part 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. Reasonable 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. 

  10.Siemens motor.
