(PDF) Rotary Dryer Handbook Niel vd Merwe - Academia

Most often, rotary dryers are of the direct-ired type, meaning that the drying air is in direct contact with the material. Some dryers, however, are of the indirect type, whereby the dryer is heated externally, to avoid direct contact between the material and the drying air. Rotary dryers are comprised of a rotating drum, into which the ...

Dryer Design: Choosing the Right Drying Technology for

5 天之前  Rotary Dryers are Direct Dryers designed with rotating, “tumbling” drums and internal lifters to “rain” the moist solid through the passing heated drying air. The challenge of this dryer is maximizing the time the wet feed is exposed to the heated drying air. The better the contact, the shorter the rotary dryer’s length and cost.
