Rotary Dryer Material Balance

Rotary Dryers FEECO International Inc

Rotary Dryers FEECO International Inc

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.
