Abstract

The invention relates to a fluidized bed reactor for the continuous production of fluidized bed granules. The reactor is characterized by a discharge device designed as a siphon pipe or siphon weir. The fluidized bed reactor permits a trouble-free continuous operation of the fluidized bed stage and of a connected, continuous subsequent stage. A preferred fluidized bed reactor comprises two chambers that are in communication via the discharge device according to the invention.
