A Rotary Dryer is an industrial drying machine that uses a rotating drum to dry bulk solids by tumbling them through a stream of hot air or gas.

Key features of a Rotary Dryer:

• Rotating drum: Material is lifted and cascaded through hot air inside a large cylindrical drum that slowly rotates.

• Efficient heat transfer: The tumbling action exposes the material evenly to hot air, promoting uniform drying.

• Versatile: Can dry a wide range of materials including minerals, chemicals, food products, biomass, and sludge.

• Continuous operation: Suitable for large-scale, continuous drying processes.

• Customizable: Drum size, rotation speed, and temperature can be adjusted based on material properties.

In short, a rotary dryer efficiently removes moisture from bulk solids through gentle tumbling and heated airflow.
