Dryer for fertilizer

1. Brief introduction of dryer for fertilizer:

Drier also named as Drying Machine and Rotary Drier.Drier is mainly consist of rotary body,

raw material feeding plate, driving and supporting device, etc

2. Application of dryer for fertilizer:

Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. Rotary dryer are widely used in building materials,

metallurgy, and chemical industry. Rotary dryer is handling by bringing it into direct contact

with a heated gas. The dryer is made up of a large, rotating cylindrical tube,the dryer slopes

slightly so that the discharge end is lower than the material feed end in order to convey the

material through the dryer.

3. Working principle of dryer for fertilizer:

Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series

of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back

off the fins, it falls back down to the bottom of the 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 co-current flow), or toward the feed end from the discharge end (known as

counter-current flow). The gas stream can be made up of a mixture of air and combustion

gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively,

the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the

gas stream is preheated by some means where burner combustion gases do not enter the dryer,

the dryer known as an indirect-heated type. Often, indirect heated dryers are used when

product contamination is a concern.
