Product Description

Rotary Dryer-Co-Current Rotary Dryers Equipment (10-120tph)

Co-current Rotary Dryers vs Counter Current Rotary Dryers

In co-current rotary dryers, the heated drying air flows in the same direction as the product, and in counter current rotary models the drying airflow travels against the flow of the product. These rotary dryers directly expose the product to hot air produced by the heat source. As the drum rotates, lifting "flights" mounted on the inside of the drum shell tumble, slide, lift and shower the material into the air stream.

Lifting flights are carefully designed to accommodate the material being dried and ensure the product is uniformly exposed. This agitation ultimately leads to higher efficiencies and reduces processing times compared to stationery units. It is not uncommon for a process taking 1 hour in a stationary furnace to take just a few minutes in a rotary dryer. A number of options for types of drying fuel and control methods are available including stand-alone microprocessor controllers or PLC controllers that directly interface with plant control systems.

Rotary Dryer Working Principle:

 

 Material to be dried enters the rotary drum 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 rotary 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) of the rotary dryer, or toward the feed end from the discharge end (known as counter-current flow) of the dryer. The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the rotary dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated.
