drying process rotary dryer

Rotary dryerswork by tumbling material in arotatingdrum in the presence of adryingair. They can also be indirectly heated to avoid direct contact between the material andprocessingmedium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum.
