The invention relates to a fluidizing plate, comprising a supporting structure and plate segments, the plate segments respectively having openings through which gas flows during operation. The plate segments are respectively releasably connected to the supporting structure and two neighboring plate segments respectively overlap and are releasably connected to one another in the region of the overlap. The invention also relates to an apparatus with such a fluidizing plate.

Fluidizing plate and apparatus comprising such a fluidizing plate

A method for the classification of superabsorber particles is disclosed, in which the superabsorber particles are put onto a top screen deck of a screening machine having at least two screen decks with a different hole size, the superabsorber particles which are smaller than the holes of the respective screen deck respectively falling through the holes and the superabsorber particles remaining on the screen deck being removed via an extraction point. Balls are positioned on each perforated plate, which balls are propelled upward by the movement of the perforated plate and strike from below the screen deck respectively lying above, wherein the balls have a stiffness in the range from 40 to 100 N/mm and a damping in the range from 1 to 4%. A machine for carrying out the method also is disclosed.
