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.
Most often, the choice for a bulk solids drying or cooling system comes down to rotary or fluid bed. While rotary equipment is especially suited to demanding applications, fluid beds are more suited to materials that are especially delicate. FEECO has been providing heavy duty, reliable rotary dryers and coolers since 1951.
