1. What the rotary dryer can be used for

This machine can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. They are widely used in mineral dressing building materials, metallurgy, and chemical industry.

 

2. what the rotary dryer consist of

the dryer is formed by rotary body, lifting blade, driving device, supporting device and sealing ring.

 

3. Working principle of the rotary dryer

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.
