Two types of roaster can be used, the spray roaster (SR) and the fluid bed roaster (FBR). ... Fluidized Bed Roaster (FBR). In the FBR, the chloride solution is introduced into a large bed of hot metal oxides, while the required energy is provided directly by the fluidizing combustion gases [followed by an illustration]. 2, record 1, English, - fluidized%20bed%20roaster

La calcination de concentrés de zinc à contenu élevé en fer pendant moins d'une minute, dans un réacteur «TORBED» à l'échelle pilote, à 975-1100 °C, a produit des quantités prédominantes d'une phase (Zn,Fe)O. Les particules de (Zn,Fe)O sont petites et retiennent la taille et la forme des grains de galène du concentré original; par contraste, la phase prédominante ZnO, faible en fer, des minerais grillés dans le four de grillage à lit fluidisé conventionnel se produit principalement en gros agglomérés à bandes rythmiques. 1, record 1, French, - four%20de%20grillage%20%C3%A0%20lit%20fluidis%C3%A9

(...) vertical chambers - usually of circular cross-section - with grate hearths through which oxygen-bearing gas, usually air, is blown. As the concentrate is fed to the chamber, air is blown through the grate at a rate sufficient to hold the solid particles in suspension, the mixture of air and solids having the flow characteristics of a fluid. Since each sulfide particle is in constant turbulent motion in the furnace atmosphere, roasting is uniform and rapid, with efficient heat transfer and high oxygen utilization. 3, record 2, English, - fluid%20bed%20roaster

Dans les fours à lit fluidisé, le minerai [le zinc] est maintenu en suspension par l'air de grillage soufflé par le bas à un débit convenable. Dans certaines conditions, le lit de minerai en suspension se comporte comme un fluide; le contact air - particules de minerai est excellent, ce qui favorise la rapidité d'oxydation des sulfures. L'alimentation peut être constituée par du minerai fin ou granulé, la granulation permettant d'éviter un entraînement de poussière important. 1, record 2, French, - four%20%C3%A0%20lit%20fluidis%C3%A9
