Abstract
A method and apparatus for heat treating a particulate product including fluidizable as well as non-fluidizable particles. The particles are fed to a first perforated bed plate of a fluidized bed apparatus comprising at least one further stage formed by a second perforated bed plate. Heat treating gas is supplied upwardly to the first and second bed plates to fluidize the fluidizable particles thereon. The non-fluidizable particles are moved from the first bed plate into at least one discharge passage opening in the first bed plate. A flow of classifying gas is directed upwardly through the discharge passage to prevent fluidizable particles from leaving the fluidized bed through the discharge passage, while non-fluidizable particles are allowed to be discharged. The fluidizable particles are transferred from the first stage into the second stage for further treatment.
