Rotary Dryer

Rotary Dryer Description:

The Rotary dryer made by our company is mainly used in building materials, metallurgy,

chemical plant, cement plant for drying of limestone slag, coal powder, slag, clay stone.

This dryer is formed by rotary body,lifting blade, driving device, supporting device and

sealing ring. The dryer has advantages of reasonable structure, high efficiency, low energy

consumption and convenient for transportation

Rotary Dryer Working principle:

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 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 whichcase 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 indirectheated type.

Often, indirect heated dryers are used when product contamination is a concern.
