Rotary Drum Dryer

A rotary drum dryer is one kind of drying machine, one of the basic machines in the wood pellet line. The drum dryer is made up of the 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 materials feed into the dryer by a conveyor, and material comes into the drum main body from the feeding chute, by the transmission of the motor, gearbox, and rolling ring, the drum main body runs and raw material moves forward in the drum, at the same time heating furnace send hot air into the drum, the blower gives 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 a conveyor to move away, the waste air will go to the pipe from the blower and be sent out, and the dust will be collected by the cyclone.

From the electric panel, the rotating speed of the drum dryer's main body can be adjusted, thus making the dryer suitable for different kinds of raw materials with different initial moisture content.

A rotary drum dryer application

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

The requirement for different initial moisture content and final dried moisture content can adjust the drum tube rotating speed to find the best solution.

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

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

Rotary drum dryer advantages

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

2. Adjusting the rotating speed can suit different initial moisture contain biomass materials and can get different moisture content after drying according to different usage and requirements.

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

4. Conveyor system feeding and discharge, labor-saving
