Rotary Drum Dryer

Product Detail

Rotary drum dryer introduction


Rotary drum dryer is one kind of the drying machine, one of the basic machine in wood pellet line. The drum dryer is made up of heating furnace, dryer drum main body, feeding chute, discharge chute, blower, cyclone, airlock, gear, rolling ring, gearbox, transmission system, electric panel and connect pipelines. The raw material feed into the dryer by conveyor, material come into drum main body from feeding chute, by the transmission of motor, gearbox and rolling ring, the drum main body running and raw material move forward in the drum, at same time heating furnace send hot air into the drum, the blower give attraction to the raw material and hot air, they move to end of the dryer, during the moving time the raw material will be dried. Final dried material will discharge from the discharge chute and use conveyor to move away, the waste air will go to pipe from blower and send out, the dust will be collected by the cyclone.

From the electric panel, the rotating speed of drum dryer main body can be adjusted, thus to make the dryer suitable for different kind of raw material with different initial moisture contain.

 

Rotary drum dryer application

The rotary dryer is used to dry wood chips, sawdust, rice husk, and any crushed biomass material which size <30mm.

For different initial moisture contain and final dried material moisture contain, can adjust the drum rotating speed to find the best solution.

Usually to make pellets, the moisture contain of final dried biomass material is 12-15%, to make charcoal briquettes, the final moisture contain after drying is 8-12%.

If you want to dry sawdust or wood powder with initial moisture <35%, have low drying capacity requirement, you can choose our flash dryer.

 

Rotary drum dryer advantages

1. Simple structure, the whole system controlled by electric panel, easy to install, operate and maintain.

2. By adjust rotating speed can suit different initial moisture contain biomass material, and can get different moisture contain after drying according to different usage and requirement.

3. Equipped with blower, cyclone and airlock, can control the dust to make the user’s factory clean, if want better dust control effect, we suggest to add pulse duster collector.

4. Conveyor system feeding and discharge, labor saving
