The design of flights in rotary dryers - ScienceDirect

Nov 26, 2001  In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat required for the vaporization of the water. To promote gas–solid contact, most direct heat dryers have flights, placed parallel along the length of the shell, which lift solids and make them rain across the section of the dryer Fig. 1).

Rotary dryers for particulate solids commonly use flights along the length of the shell to lift solids and make them rain across the dryer section. These flights are critical to dryer performance. Previous models for the prediction of the solids holdup in rotary drums have assumed that the angle of the solids level in a flight is independent of ...
