How The Rotary drum Dryer Works:

The wet material is added from the feeder to drum body. Cylinder has a certain inclination and rotates continuously, which makes the material under the action of gravity move from high to low. Materials and high-temperature flue gas as a drying medium enter into the dryer cylinder body under the action of the suction of the exhaust device . Material in the process of gradually moving exchanges heat with high-temperature flue gas in the way of convection, radiation, conduction. The material is heated, the water evaporation to dryness medium, and the water contained in the material is taken away, which is the mass transfer process.

After drying, the material is discharged from the low-end, the material residence time in the dryer about 20 to 40 min. Exhaust gas also flows from low pressure site to high pressure site. Material is unloaded from the dryer after drying and the exhaust gas is discharged to the atmosphere by the dust collector.

Rotary drum dryer main features:

1. The dryer is of strong overload capacity resistance, large process load, low fuel consumption, and low cost.

2. It adopts direct flow drying method. The gas fume and the material go to the dryer from the same side. By using the hyperthermia gas fume, the evaporation strength is very high. With the low outlet temperature, the heat efficiency is very high.

3. The operating parameter can be changed according to different materials. So that the material can form a stable fabric curtain and achieve fully heat exchange.

4. The new type feeding and discharging device solve the problem of feeding jam, discontinuous and uneven feeding, and returning charge which lighten the load of dedusting system.

5. The new inner structure strengthens the cleaning and heat conduction of the dispersed material, and eliminates the bonding in the inner drum wall. The adaptability to the material moisture and stickiness is stronger.
