| Zusammenfassung: | A rotating seal device for a rotary drum kiln. A rotating seal member is welded about the drum near each of its ends, each sealing against a rotationally stationary seal member joined with the associated kiln end hood through a flexible gas tight bellows. The stationary seal rides on a pair of rollers each bearing upon a track, preventing its rotation. The bellows accommodates longitudinal expansion and contraction of the drum. Hanging weights are used with pulley wheels and flexible cables to urge the non-rotating members against the rotating members with unvarying force. |
