Abstract
In order to separate two classifiable materials, a material classifying apparatus includes a vibratory conveyor for conveying a fluidizable material from a material to be separated therefrom from an inlet end through a material separation section to an outlet end located downstream of the material separation section. A plenum chamber directs air upwardly through the fluidizable material and the material to be separated therefrom in the material separation section of the vibratory conveyor to cause fluidization of the fluidizable material and separation of the material to be separated therefrom by forming the material separation section to include a fluidizing deck for supporting the two classifiable materials while accommodating passage of air upwardly from the plenum chamber therethrough. With this arrangement and construction, the upper surface of the fluidizing deck has fluidizing zones for stabilizing the fluidizable material on the fluidizing deck to produce a uniform airflow through the fluidizable material to facilitate separation of the material to be separated therefrom upstream of the outlet end of the vibratory conveyor.
