Abstract
Apparatus for coating particles with a substance contained in a reactant gas, the particles being suspended in a fluidized bed within a coating chamber, an elongated nozzle extending upwardly from the coating chamber base with an outlet for reactant gas being substantially above the base to direct the reactant gas into a dilute phase region of the particles. With the base of the chamber being an inverted conical member, coated particles are preferably removed from the chamber by means of a movable plug forming the apex of the conical member, the elongated nozzle preferably being mounted upon the unloading plug.
