Rotary Drum Dryer

The new type of rotary wood chips dryer is shaped as a horizontally inclined rotating cylinder. Wet wood chips are feed at feed port and discharged at the output port. In direct-type rotary dryer (cylinder drier), hot air moves through the cylinder in direct contact with the material in the dryer, either downstream or against the direction of its flow. The wood chips rotary dryer is equipped with scatters equipment, make wood chips fully touched with the hot air, so that has a very good drying effect.

Product Details

Rotary drum dryer machine is the mechanical equipment using the heat energy to reduce the water of materials. It could dry the bigger materials such as wood chips, waste wood, wood shavings, sawdust and other kind of crushed straws.

Three channels rotary drum dryer is used to dry materials, it equipped with cyclone dust collector, which has features of high efficiency, energy-saving, and small floor space. Compared with other dryer machines, it saves energy by 30%-50%, thus maximum saving energy and drying cost.

Rotary drum dryer is designed with rotary type, and rotary drum drying machine can remove the moisture of wood materials perfectly, The working temperature of rotary drum dryer machine can reach up to 150℃-180℃ and the water content of wood shavings is below 10% after drying.

Simple design, self-insulation, and improving the heat efficiency to exceed 80%. Meantime, good drying performance, coal consumption < 8kg when drying 1 ton material.

Finished product moisture can be adjusted according to the different requirements. Meanwhile, finished product temperature lower than 60°C, and working continuously.

Working principle of rotary drum dryer

Rotary drum dryer is consists of a heating device, feeding device, transport device, discharge device, dust extraction device and other connecting parts. For the installation process, the rotary drum dryer should slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the rotary drum dryer under gravity. Material to be dried enters the rotary drum dryer, and as the rotary drum dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the rotary drum dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the rotary drum dryer, passing through the hot gas stream as it falls.

Structure Feature of Rotary Drum Dryer

1. Rotary drum drying machine mainly is composed of four parts: drum, conveyor (two sets), cyclone, blower, control box, silo, burner and supporting equipment.

2. The internal of rotary drum dryer adopts assembled structure which improves the accuracy, and it is easy to transport and install. Compared with single-layer dryer, three-layer rotary drum dryer reduces the area of about 50%, and reduces civil construction investment by 50% or so.

3. Rotary drum dryer adopts assembled lifting board so as to exchange heat fully and lower the energy consumption.

4. Rotary drum dryer is equipped with temperature induction monitor, uniform vibration and airproof setting, to improve performance and productivity efficiently.

5. Supporting a variety of new energy-saving hot stove, energy efficient, heat control, simple operation, energy consumption down as high as 30%, 20% lower power consumption, lower operating costs.
