Single Drum Dryer

Material flow :  The material with a moisture content of 75-85% is fed into a specialized dehydration machine. The screw conveyor removes water to about 65% before it is sent downstream for drying in the mixing drum dryer. The flights within the drum pick up the material, carrying it over and showering it through the air stream as the drum rotates. This promotes maximum heat transfer efficiency between the material and the drying air, resulting in rapid water vaporization and material drying under the hot air's rapid flow.

To prevent buildup near the wet material discharge, the rotary drum dryer allows the material to dry before it reaches the next set of flights. Furthermore, a drum cleaning device is installed within the drum to prevent any sticking issues with the material.

The hot air furnace increases the air pressure through an air blower, heating the air to 600-850℃. Once the temperature is reached, the hot air enters the dryer and dries the wet material, and evaporates the water through the inducing draft fan. Through a three-layer heat transfer process, the air temperature reduces to 55-65℃ before being discharged from the dryer. Finally, the dust and moisture are purified through the cyclone dust collector and wet dust collector.

Airflow :  The air is pressurized by the air blower and enters the hot air furnace for heating. When the temperature reaches 600-850℃, the hot air is introduced into the dryer to dry the wet material and evaporate the water with the help of the inducing draft fan. Through a three-layer heat transfer process, the air temperature gradually reduces to 55-65℃ before being discharged from the dryer. The dust and moisture are then purified through the cyclone dust collector and wet dust collector.
