3.3 Rotary Dryers 17 3.3Rotary Dryers Consists of a revolving hollow cylindrical shell, horizontal or slightly inclined towards the outlet. Figure 5: Photograph of a rotary dryer. As the shell rotates, internal ights lift the solids and shower them down through the interior of the shell. May be direct or indirect contact or a combination of both.
1) Thermal inefficiencies in the dryer: exhaust heat content in convective dryers, sensible heating of solids, heat losses from dryer body. 2) Thermal inefficiencies in the utility (heat supply) system: steam generation efficiency, steam leaks and mains losses. 3) Additional energy demands: power for solids transport, vacuum pumps and air fans.

6. A rotary dryer consists of a cylindrical shell, set with its axis at a right angle to the horizontal and mounted on rollers so that it can be rotated. The material to be dried is fed to the high end of the dryer and, by rotation of the dryer, usually assisted by internal shelves of flight, is gradually advanced to the lower end where it is discharged.
FurnXpert Rotary Dryer software helps engineers design and size Industrial Rotary Dryer for processing granular material (feed) in Rotary Dryers. Usually feed contains certain amount of moisture.
3.1 Rotary Dryers Rotary dryers potentially represent the oldest continuous and undoubtedly the most common high volume dryer used in industry, and it has evolved more adaptations of the technology than any other dryer classification. All rotary dryers have the feed materials passing through a rotating cylinder termed a drum. It is
