Abstract
A fluidized bed particulate material treating apparatus is provided having a fluidizing bedplate formed with apertures of a frusto-conical configuration. The apertures are formed with walls divergent from an exit end at an angle in the range of 25-45 degrees with a plurality of apertures formed in the bedplate in closely spaced relationship resulting in interaction of the airflow from the apertures to levitate the material as it is transported over the bed by the air flowing through the apertures.
