Product Description

Ulexite and Borax rotary dryer
This is an indirect heating type of rotary dryer that brings materials into indirect contact with heating medium to provide heat exchanging.
The indirect heating type of rotary dryer is classified into external heating rotary dryer and steam tube dryer, which are applied for the following conditions.

If you use materials that are easily affected by contact with combustion gas.
If you need to minimize the amount of exhaust gas from the dryer.
If you use materials that are apt to produce dust.
If you use materials that are easily affected by oxidation.
If you need to recover volatile component.

Working Principle

The indirect heat rotary drum drier is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. 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 under gravity. 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).
