ABSTRACT:
An air classifier for the separation of refuse by density into homogeneous fractions. A waste bin discharges non-homogeneous waste which is dispersed within a mixing chamber whereat a pressurized airflow, moving upwardly therethrough, carries lighter particles upwardly into a main duct structure. Subjacent the mixing chamber, is a crossflow zone through which a secondary airflow moves transversely to waste gravitating from the mixing chamber. The classifier air duct is of irregular shape having enlarged portions, spaced therealong, each constituting a waste separating station whereat waste of like density gravitates into a discharge chute associated with the station. Air inlet means at each station directs a crossflow of air onto the gravitating waste matter to remove lighter density particles comingled therewith and reentrain same in the main duct airflow. The crossflow of air additionally serves to wash an inclined surface of the main duct picking up particles and returning same to the main duct airflow while obviating undesired vortex formation. An auger housing, below each waste separation station, further classifies waste separated at that station by its physical size.
