Rotary dryer

Working Theory of Rotary Dryer:

The wet materials are transported into the material hopper by the belt conveyor and bucket elevator, and gets into the feeding terminal through feeding pipe with the aid of feeder of material hopper. The pitch of the feeding pipe should be more than the natural pitch of materials in order to help the materials flow into the dryer successfully. The cylinder of dryer is a rotary cylinder which is oblique slightly. The materials are fed from the relatively higher terminal, heat carrier comes in from the lower terminal, and sometimes the heat carrier and materials get into the cylinder together. Along with the revolving of cylinder, the materials move to the lower terminal due to the gravity. When the wet materials move forward, it receives the heat from the heat carrier directly or indirectly. As a result, the wet materials are dried, and discharged out by belt conveyor or screw conveyor on the outlet. There is shoveling plate inside the cylinder in order to shovel materials up and cast it out, to increase the connection surface, to promote drying efficiency, and accelerate the forward movement of materials. Generally, the heat carrier can be hot air and chimney flue. After the heat carrier is dried, the materials mingled with air should be collected with cyclone dust collector. If there is need to reduce the content of dust mixed with tail gas, the heat carrier should be subject to bag dust collector or wet dust collector before it is discharged.

Performance and Feature of Rotary Dryer:

The rotary dryer mainly consists of rotor, shed plate, transmission device, support device, seal ring, and other spare parts. The rotary dryer has the advantages of reasonable structure, excellent manufacture, high output, low energy consumption, convenient operation and so on. The rotary dryer is applicable for particle materials, and is also applicable for paste and viscous materials which are mingled with particle materials, or materials whose water content is high. It has the advantages of large production volume, wide application range, small flow resistance, large adjustable range, and convenient operation, etc.

Application

This machine can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. They are widely used in building materials, metallurgy, and chemical industry.
