BEST PRACTICE MANUAL DRYERS
3.1 Rotary Dryers Rotary dryers potentially represent the oldest continuous and undoubtedly the most common high volume dryer used in industry, and it has evolved more adaptations of the technology than any other dryer classification. All rotary dryers have the feed materials passing through a rotating cylinder termed a drum. It is
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.
