Hot Sale Industrial Rotary Drum Dryer

The Rotary dryers characteristics:

1. The internal adopts assembled structure which has improved the accuracy of the equipment and it is easy to transport and install.

2. According to the characteristics of different fertilizers, we have arranged the second granulation zone reasonably so as to improve the granulation effect.

3. Adopts assembled hoist board so as to exchange heat fully and lower the energy consumption.

4. Temperature induction monitor, uniform vibration and airproof setting, which improve performance and productivity efficiently.

5. The assorted combustion furnace is a type of energy efficient and has the characteristics of smaller area, easy regulation and equipped with greenhouse

Working Principle of 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.
