Rotary Drum Dryer
Rotary Drum Dryer
Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.
Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium.
The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.
Features:
- Diameter: 1 – 2.2 m
- Capacity: 1 TPH – 30 TPH
- Specially designed lifting flights to maximize heat transfer between the material and hot gas stream
- Heavy duty design and construction for many years of service
- Co-current (parallel flow) or counter-current configuration
- Process and Mechanical Warranties
We can offer cost competitive designs for pilot scale units that process as little as one ton per hour to heavy duty units that process thirty tons per hour.
