Working principle of the 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.

The main characters:

1. The dryer resistance overload ability strong, large quantity, fuel consumption less, dry cost is low;

2.adopt co-current drying method, smoke and wet materials by the same side into the dryer, can use             obtained high temperature flue gas evaporation strength, dryer outlet temperature of low and high                thermal efficiency,

3. According to different material properties change operation parameters, make the material in the dryer       cylinder body can form a stable all broken fabrics act, qualitative heat more fully,

4.materials feeding and discharging device, to eliminate the drum drying machine feeding jams,                      discontinuity, uneven regurgitation feeding etc. Phenomenon, reduced dust removal system load,

5. New internal structure, strengthened the already scattered materials for the cleaning and heat transfer         effect, eliminates the cylinder body wall with sticky phenomenon, for material moisture, sticky                     adaptability stronger;

6. The dryer has realized "zero horizontal thrust", greatly reducing the block roller wear, cylinder smooth       operation and reliable;

7. The dryer adopt "self-aligning type roller device", make roller and coordination of the tyre-roller forever      linear contacts, which greatly reduces the wear of power loss,

8. Optional according to customer's requirement control product size and moisture, drying slime water            when products can reach 8% below, and the particle can be controlled in 8mm below.

Rotary dryer Structure:

Rotary dryer machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.
