2.Small wood chips rotary drum dryer structure:
1 Small wood chips rotary drum dryer is mainly composed of rotary part, lifting board, transmission part, supporting part and seal ring.
2 The drum dryer produced by our company uses reasonable running parameters, and the coal and electricity consumption is reduced by over 10-15% and the output per machine is improved by over 10-15%, so that it has been widely used in the cement plants and ore beneficiation plants.
♦ Gear Material: Cast steel
♦ Discharging way: Downstream
♦ Drum Material: Heat-resisting steel sheet
Preface
Wet material is loaded from one head of the dryer, and then it is stirred by the bafflers that is uniformly distributed in the barrel. Material is uniformly distributed and dispersed in the dryer, fully contact the hot air of parallel (or counter) flow, so the drying process is expedited, and the impulsion power of media transfer is enhanced. During the drying process, material is under the effect of angled baffler and hot air, moves to the star shape unloader that is at the other head of the dryer.
Structures
The rotary dryer is mainly composed by the revolving body, lifting
plate, driving device, supporting device, sealing ring and other
components. So it has the advantages of reasonable structure,
perfect in workmanship, high yield, low energy consumption,
convenient to operate.

1. The motorization level of the barrel is high, and the production
capacity is high;
2. The resistance that the material passes through the barrel is
less, and the power consumption is low.
3. Application capability to different characters of materials is
high.
4. The operation is stable, the operation fee is low, and the
uniformity of product drying is good.
5.The rotary dryer is mainly composed by the revolving body,
lifting plate, driving device, supporting device, sealing ring and
other components. So it has the advantages of reasonable structure,
perfect in workmanship, high yield, low energy consumption,
convenient to operate.
