Title (EN) PROCESS AND DEVICE FOR DRYING AND/OR BURNING POWDERY MATERIALS
(FR) PROCEDE ET DISPOSITIF DE SECHAGE ET/OU DE CALCINATION DE MATIERES PULVERULENTES
Abstract:
(EN) The device comprises at least a feeding station (16, 18, 20), a heated processing chamber (22, 24, 26) and at least one material removing device (28, 30, 32). The processing chamber is formed with a bottom (40, 42, 44) which can vibrate and be penetrated by a throughflow of gas.
(FR) Un procédé et un dispositif sont utilisés pour sécher et/ou calciner des matières pulvérulentes. Le dispositif comprend au moins un agencement d'alimentation (16, 18, 20), une chambre chauffée de traitement (22, 24, 26) et au moins un agencement d'évacuation (28, 30, 32) du matériau. La chambre de traitement est pourvue d'un fond (40, 42, 44) susceptible d'être traversé par un courant de gaz et d'être mis en vibration.
