Rotary Drum Dryer

The Performance Characteristics of Rotary Drum Dryer:

  • 1. No air leakage phenomenon which completely solves the sealing difficulties and can be installed within two hours.
  • 2. According to users' requirements, it can easily control the demand final moisture indicator.
  • 3. The discharge temperature is below 50 degrees and can be directly fed into the cooling shed.
  • 4. Low energy consumption, low investment, cost saving, energy saving and environmental protection.

Working Process:

Materials enter into the inner side of the drum through the feeding device to achieve current flow drying process. They get raised and scattered under the shoveling plate in a spiral advancing way to exchange heat. Then they enter the middle layer of the inner wall through the other end to achieve counter current drying process.

Parts of the rotary drum dryer

They absorb heat from both inner drum and middle drum and extend the drying time to realize the best drying condition. Finally, materials fall into the outer layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain to stay in the drum because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus, the whole drying process has been finished.
