ABSTRACT:
Gyratory and reciprocal motion classifiers for classifying particles in a fluidized particle bed according to size or density, and implementing a classification chamber for the fluidized particle bed and an activation chamber for enhancing the kinetic energy of particles prior to their introduction into the classification chamber. The activation chamber is movable with the classifier and preferably has a vertical thrusting surface and lateral surfaces convergent toward an exit opening which admits particles into the classification chamber in proximity to an upstanding surface for dispersing particles away from the point of entry and over and into the fluidized bed in a direction counter to the directional throw of the particle bed-supporting surface of the classification chamber.
