Triple Pass Rotary Drum Dryer Industrial Drying Equipment/Rotary Dryer Coal
Equipment Introduction:
The three cylinder industrial drying equipment improves the internal structure on the basis of single drum
dryer, the pre drying of wet material is added before getting into the dryer and prolong the drying time of
wet material in the dryer.
Drying Materials:
Powder, coal, sand, clay, slag, etc.
Performance Characteristics:
1. Low outlet air temperature, longer service life of dust removal equipment.
2. Sizes of lump materials, particles, and powders are less than 20mm can be dried.
3. Gear driving is not required and it’s directly driven by roller, with higher mechanical efficiency.
4. Without the phenomenon of air leakage, the sealing difficulty is totally solved, and the installation can
be finished within a few hours.
Working Principle:
Materials get into the internal rotary drum from the feeding device, to realize the downstream drying,
materials are lifted up and down constantly by the inner layer lifting plates and the heat exchange is
realized under the form of spiral moving, materials move to the other side of the inner cylinder and then
get into the middle cylinder, and materials are lifted up and moved forward in the middle cylinder, by the
way of two steps forward and one step back, materials absorb the heat both coming from the inner
cylinder and the middle cylinder, meanwhile, the drying time is prolonged, and materials reach optimum
drying status at this stage. Material move the other end of the middle cylinder and then get into the
outer cylinder, the dried materials are quickly discharged from the cylinder under the function of hot
wind.
