In the heat treatment of fine-grained mineral solids, in particular for calcining clay or gypsum, the solids are passed through a flash reactor (5), in which they are contacted with hot gases at a temperature of 450 to 1500°C, and subsequently they are passed through a residence time reactor (7) at a temperature of 500 to 890°C, from which they are withdrawn after a residence time of 1 to 600 minutes and possibly supplied to a further treatment stage. |
