Abstract: The invention relates to an apparatus for producing pulverulent poly(meth)acrylate, comprising a reactor for droplet polymerization having an apparatus for dropletization of a monomer solution for the preparation of the poly(meth)acrylate having holes through which the monomer solution is introduced, an addition point for a gas above the apparatus for dropletization, at least one gas withdrawal point on the circumference of the reactor, a fluidized bed and an apparatus for product discharge from the fluidized bed. The apparatus for product discharge comprises a discharge apparatus, with a backup segment (39) disposed above the discharge apparatus.
