Rotary Dryer Introduction
HC series rotary dryer is also called roll dryer, which is handling by bringing it into direct contact with
a heated gas. The rotary dryer 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.
Rotary Dryer Working principle
Material to be dried enters the rotary dryer, and as the rotary dryer rotates, the material is lifted up by a
series of internal fins lining the inner wall of the rotary dryer. When the material gets high enough to roll
back off the fins, it falls back down to the bottom 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), or toward the feed end from the discharge end (known as countercurrent 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 gas stream may consist of air or another (sometim
es inert) gas that is preheated. When the gas stream is preheated by some means where burner
combustion gases do not enter the dryer, the rotary dryer known as an indirectheated type.
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. Operartion is easy and could use for many years.
