How It Works
The heat source for the rotary drum dryer comes from a combustion unit. The dryer uses a counter-current heating mode, where hot air enters the dryer from the discharge end. The material to be dried enters the inclined rotating drum from the feed box and is pushed to the back by a screw lifter. As the drum rotates, the material tumbles and is repeatedly scooped up and dropped by the lifter flights. This allows for thorough heat exchange with the hot air, gradually drying the moisture from the material.
