Application of Rotary Dryer

Rotary Dryer is widely used in building material, metallurgy, chemical engineering, and cement industries for the drying of slag limestone, powdered coal, slag and clay. This dryer consists of rotary body, throwing flitch, transmission device, supporting device and sealing ring.

 Working principles of Rotary Dryer

The raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder ,then water will be separated from the materials by hot air-flow and changed into vapor to be discharged into the atmosphere, then the materials would be dried .

 Main features of Rotary Dryer

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 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.

6.The zero level thrust of the dryer reduces the abrasion to the catch wheel and the riding wheel. The operation of the rotary drum is stable and reliable.

7.The dryer adopts the riding wheel device, which keeps the riding wheel and the rolling ring linear touch all the time. Thus the abrasive and the power loss are greatly reduced.

8.The granularity and the moisture can be adjusted by the customer’s demand. When drying the coal slurry, the product moisture can be less than 8% and the granularity less than 8mm.
