High Efficiency Biomass Rotary Drum Dryer With 30-40% Water Reducing Ability

High Efficiency Rotary Dryer

Rotary dryer is designed to dry wood chips, sawdust, wood shavings, bagasse, grinded fiber from EFB, coconut shell, straw, stalk and any biomass material. It can reduce the moisture from 50-60% to 8-12% according to different requirement on the final usage of dried material.

Rotary dryer is made up of main drum tube, base rolling roller, reducer/gearbox, feeding chute, discharge chute, heating stove, air fan, cyclone, air lock, connection pipes and electric panel.

* The drum tube is the main part of rotary dryer, the diameter and length of the drum tube decide the capacity of rotary dryer and moisture reducing ability of rotary dryer. Inside the drum tube there is material raising plate, these plate is welding inside the drum tube by special design, the position and angle of these plate can raise up the material and move the material from feeding end to discharge end when material padding the drum tube.

* During material passing the drum tube, material mix with hot air supplied from heating stove, the hot air can vapor the water content in raw material.

The heating stove have different solutions:

Traditionally use common heating stove building by cement and firebricks, this kind of heating stove use wood or biomass material ass fuel source.

Nowadays, people also use furnace to provide hot air to rotary dryer, the furnace can use wood pellets, sawdust, wood chips, natural gas or heavy oil as fuel source

Some client have big generator on site, also can send the waste air from generator to drum tube to provide heating source.

* The rolling rollers and reducer is the base of drum dryer, the rollers and gear form transmission system to drum tube, the motor of reducer is VFD control from electric panel, it can adjust the rotating speed of drum tube so that to control the moisture reducing ability. If the raw material moisture content is relative high adjust from the VFD to let drum tube rotating slower, if raw material moisture content is relative low adjust from VFD to let the drum tube rotating faster.

* The air fan is installed at end of drum dryer, it is used to provide suction to drum tube thus to move out the vapor from drum tube, at end of drum tube, the dried raw material discharged from the discharge chute, and the air fan suction the vapor and dust then send them to cyclone unit.

* The cyclone and airlock is used for de-dust purpose at end of drum dryer.

Advantage of drum dryer

  • Simple structure, easy to operation
  • Widely application, suitable for different kind of raw material
  • Gear transmission system, the drum tube is transferred by the gear on the tube and reducer, to improve transmission efficiency
  • Drum tube rotating speed adjustable from the VFD in electric panel, to meet different drying requirement.
  • High moisture vapor ability
  • Conveyor system feeding and discharge, labor saving
  • Equipped with air fan, cyclone and airlock, can control the dust to make the user’s factory clean, if want better dust control effect, we can provide pulse duster collector.
