| 摘要 |
The invention relates to a process and an apparatus for the thermal treatment of powdered or granular solid substances with gas flows (7, 16, 22, 23, 24) by means of a body (2) moved about its axis of rotation (1). In this process, the following process steps are successively carried out: Firstly, the bulk material held in segments (3) of the moved body (2) is heated by subjecting it to steam (22). Then, the heated bulk material is exposed to a feed of air (23) and/or inert gas (24), taking place in one or more subsequent steps. Finally, removal (17) of the dried or inerted bulk material from the segments (3) of the body (2) moved about its axis of rotation (1) takes place. |
