ABSTRACT:
A classifying system including an air elutriation device is disclosed, which device is in the form of an upright box defining an airflow chamber open at its lower end and connected at its upper end to an exhauster device. A mixture of particulate materials is admitted into the chamber through a slot in the side of the box above a series of rods which extend across the chamber and are adjustable for varying the rate and turbulence of the airflow in the admitting zone to separate the lighter particles from the heavier particles in the mixture with the lighter particles being carried by the airflow upwardly and out of the chamber. The heavier particles fall downwardly through the chamber into a collecting hopper disposed beneath the open lower end of the box and having its upper open end appropriately dimensioned such that the velocity of the ingress of air into the chamber will result in the air stream velocity in the admitting zone above the bars not exceeding the separation velocity for the materials introduced through the feed slot. Additional separation and classifying components may also be included in the system.
