Introduction of air flow pipe dryer,rotary drum dryer

HC series rotary dryer is also called roll dryer, which is handling by bringing it into direct contact with a heated gas.The rotary deyer is made up of a large,rotating cylindrical tube.The rotary dryer slopes slightly so that the discharge end is lower than the material feed end in order to cnonvery the material through the rotary dryer under.

Advantages of our rotary drum dryer

1.The roller of dryer uses assembled structure, it is easy to transport;

2.Added to granulation area, improves the granulation effect, increase the surface finish and 

strength of particle;

3.The baking plank adopts modular structure, for the fertilizer can be full of the whole cylinder section, so that the heating exchange thoroughly.

4.Set with thermometer, vibration device,sealing devices, improves production efficiency.

5.The structure is simple and maintenance is easy.

6.Operation is easy and owns a long service lifetime.

7.Could be the good one and 

Working Principle of rotary drum dryer 

Material to be dried enters the rotary deyer and as the rotary dryer rotates,the material is lifted up by a seriws of internal fins lining the inner wall of the rotary dryer.When the material gets high enough to roll back pff the fins,it falls back down to the botton of the rotary dryer,passing through the hot gas stream as it falls.This gas stream can either be moving toward the discharge end from the feed end (known as cocurrent flow).The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the rotary dryer is called a direct heated dryer.Alternatively, the gase stream may consist of air or another(sometimes inert)gas that is preheated.When the gase stream is preheated by some means where burner combustion gases do not enter the dryer, the rotary dryer known as an indirect heated type.Often,indirect heated dryers are used when product contamination is a concern.
