Advantages of BH Single Cylinder Rotary Drum Dryer




Long service life

  1. Supporting wheel design: Ensures long service life, reduces shaft breakage, and shortens replacement cycle.

  2. Steel dryer cylinder: Higher hardness, toughness, and wear resistance compared to other materials.

  3. Improved performance: Reasonable structure design and steel cylinder enhance durability and efficiency.



High efficiency


  1. High airflow speed: Ensures effective dispersion of the material in the air phase.

  2. Increased drying area: All material surfaces are efficiently dried, leading to a significant increase in the drying area.

  3. Enhanced efficiency and heat transfer: Dispersion and agitation during drying constantly update the aerification surface, improving efficiency and the heat transfer process.


Environmental protection

  1. Good sealing system: The single cylinder rotary drum dryer features a reliable sealing system that prevents leakage and ensures efficient drying.

  2. Perfect dust removal device: Equipped with an effective dust removal device, the dryer minimizes dust emissions, providing a clean working environment.

  3. LX type multi-combined lifting plate: This innovative design allows the material to enter the drying cylinder and form a rain-like curtain. It increases the contact surface between the material and hot air, improving the drying efficiency and preventing thermal cavitation.


Advanced structure

  1. Enhanced cleaning and heat conduction: New internal structure improves cleaning and heat transfer for dispersed materials.

  2. Eliminates sticky phenomenon: Prevents material from sticking to the inner wall of the cylinder.

  3. Improved adaptability: Stronger adaptability to varying material moisture and viscosity.

Working principle of Single Cylinder Rotary Drum Dryer

1. Material feeding: The material enters the single rotary drum dryer through the feed inlet.

2. Internal heating: The heat source is provided by the burning chamber, and the heat flow enters the dryer through parallel-flow heating method.

3. Pushed by spiral board: Upon entering the dryer, the material is immediately pushed back by the spiral board to initiate the drying process.

4. Gravity and rotation force: Due to the inclined installation of the dryer, the material flows towards the tail end under the influence of gravity and rotation force.

5. Heat exchange: The material is repeatedly lifted and thrown down by the spiral board, forming a uniform curtain for sufficient heat exchange with the internal heat flow to facilitate drying.

6. Drying and discharge: After thorough drying, the material is discharged from the tail end of the dryer, completing the entire drying process.
