Sand Dryer Sand And Hot Air Flow Mechanism

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
