1. The description of rotary drum dryer:
Rotary drum dryer is also called roll dryer, which is handling by bringing it into direct contact with a heated gas. The rotary drum dryer is made up of a large, rotating cylindrical tube, The rotary drum dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.This kind of rotary drum dryer has introduced advanced technology,through continuous transformation, it has been able to meet production needs of different countries.
2. The characteristic of rotary drum dryer:
(1) Environment-protecting and energy-reducing.
(2) Less investment, supporting civil works.(3) Reliable, simple operation, convenient maintenance, safe and durable.(4) Meet the material widely.(5) Continuous work, large capacity.
3. Working principle:
The raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapor to be discharged into the atmosphere. Then the materials would be dried.
4. Applications of rotary drum dryer:
Drying equipment can be widely used in activated sludge, sewage sludge,petrochemical sludge, paper sludge,dyeing sludge, tannery sludge,electroplating sludge, municipal sludge,bacterial bio - fermentation residue, various of sludge and residue and high humidity materials.
