Device for bringing substances, especially dispersed substances and/or solid-liquid dispersions and/or liquid substances into contact with each other and/or with gases with the aid of a rotary fluidisation system, especially for performing drying, granulation and dressing (coating) operations. This device is characterised in that the said layer support 7 comprises, between the vertical geometric axis x of the device and the gap 41 between the bottom of the support 7 and the casing, at least one intermediate annular slot 42, 43 and a conical part 5 concentric with this geometric axis and widening downwards and in that the said layer support 7, or at least its central conical part, can be raised and lowered. L'INVENTION CONCERNE UN DISPOSITIF DE MISE EN CONTACT DE SUBSTANCES, NOTAMMENT DE SUBSTANCES DISPERSEES ETOU DE DISPERSIONS SOLIDES-LIQUIDES ETOU DE SUBSTANCES LIQUIDES L'UNE AVEC L'AUTRE ETOU AVEC DES GAZ A L'AIDE D'UN SYSTEME DE FLUIDISATION ROTATOIRE, NOTAMMENT POUR LA MISE EN OEUVRE DE PROCESSUS DE SECHAGE, GRANULATION ET REVETEMENT (ENROBAGE).CE DISPOSITIF EST CARACTERISE EN CE QUE LEDIT SUPPORT DE COUCHE 7 COMPORTE, ENTRE L'AXE GEOMETRIQUE VERTICAL X DU DISPOSITIF ET L'INTERVALLE 41 ENTRE LE FOND DU SUPPORT 7 ET LE CARTER, AU MOINS UNE FENTE ANNULAIRE 42, 43 INTERMEDIAIRE, AINSI QU'UNE PARTIE CONIQUE 5 CONCENTRIQUE A CET AXE GEOMETRIQUE ET S'ELARGISSANT VERS LE BAS ET EN CE QUE LEDIT SUPPORT DE COUCHE 7, OU AU MOINS SA PARTIE CONIQUE CENTRALE, PEUT ETRE RELEVE(E) ET ABAISSE(E).
