Material flow is 75-85% moisture content of the material fed into the special dehydration machine, the water removed to about 65% through the screw conveyor into the mixing drum dryer to downstream drying. Flights pick up material, carry it over, and shower it through the air stream as the drum rotates, promoting maximize the efficiency of heat transfer between the material and drying air. The rapid evaporation of water vaporization, to achieve the effect of drying materials in the hot air under the rapid flow of the drum. The rotary drum dryer gives the material a chance to dry before it hits the next flights, in order to prevent buildup near the wet material discharge. The drum cleaning device is installed inside of the drum to prevent the material sticking issue.

    Air Stream Flow as Below: The air through the air blower increase pressure into the hot air furnace to heating, when the temperature reached to 600-850℃, the hot air will be into the dryer to drying wet material and evaporation water by inducing draft fan. Through three-layer heat transfer, the air temperature reduces to 55-65℃ and then discharge from the dryer. The dust and moisture are purified through the cyclone dust collector and wet dust collector.
