Abstract

Dispositif utilisé pour faire gonfler une matière granulaire consistant à former des flux montants de gaz chauds et de matière granulaire et à former un flux montant supplémentaire (18) de jets de gaz au contact de la partie inférieure du flux montant principal (12) des gaz chauds, et ayant une vitesse dépassant celle du flux principal (12) des gaz chauds. Ensuite la matière granulaire est chauffée jusqu'à obtention de grains gonflés de ladite matière, lesquels sont ensuite transportés de la zone de chauffage à une zone de décantation, et les grains non gonflés ainsi que les particules de roche résiduelles sont transportées jusque dans la partie inférieure du flux montant principal (12) des gaz chauds, les grains non gonflés de la matière étant transportés jusque dans la zone de chauffage afin de produire ultérieurement des grains gonflés de ladite matière. Un dispositif utilisé pour faire gonfler une matière granulaire comprend, mutuellement interconnectés, une chambre préliminaire (1), une chambre de travail verticale (3), une chambre de réception (35) ainsi qu'une chambre de décantation (47). Du côté de l'extrémité inférieure de travail de la chambre de travail (3) sont montés des moyens (11, 13) destinés à l'alimentation en combustible et en matière granulaire. Dans la partie supérieure de la chambre préliminaire (1) est monté un collecteur annulaire (17) relié à une source d'air comprimé et au contact des moyens (11, 13) d'alimentation en combustible et en matière granulaire, la paroi supérieure du collecteur étant dotée d'ajutages (24). Dans la partie supérieure de la chambre de réception (35) est monté un dispositif (39) destiné à abaisser la température des gaz sortant, et le passage (44) des gaz est doté d'un échangeur thermique (49).
