Abstract: A process for the production or coating of granules in a fluidized bed, which includes heating a fluidized-bed gas to produce the fluidized bed, and applying a liquid medium containing a granule-forming or coating-forming compound, or at least one reaction component therefore, by spraying particles located in the fluidized bed and at a same time vaporizing an organic solvent contained in the liquid medium, said particles having a smaller mean diameter than that of particles to be produced. The process also includes partial condensation of an organic solvent from at least a portion of a fluidized-bed waste gas leaving the fluidized bed, and re-heating the fluidized bed-gas leaving the condensation device and reintroducing the re-heated gas into the fluidized bed.

Abstract: A continuous process and apparatus for the production of at least approximately spherical, substantially solid particles, in which the particles are granulated in a circulating fluidized bed. This can be achieved by spraying a suspension or a solution of the solid which forms the particles into a chamber. A drying gas is passed through the chamber at a velocity which is sufficient to effect pneumatic conveying of already partially dried or agglomerated particles. The particles conveyed by the drying gas stream are separated from the exhaust gas stream and returned, at least in part, to the chamber. Particles with a size within the desired particle size range are continuously discharged from the chamber, such that the mass present in the chamber remains constant.
