Abstract:
An air separator system for separating particulate material into coarse material and fine material, comprising:a housing having an outer wall and an inner wall in a spaced relationship defining an outer cavity between thereof, wherein said inner wall defines an inner cavity;an outer discharge nozzle within said outer wall for dispensing material within said outer cavity;an inner discharge nozzle within said inner wall extending through said outer wall for dispensing material within said inner cavity;a return opening within said inner wall for allowing air from within said outer cavity to return to said inner cavity;a fan structure rotatably positioned within said housing for forcing airflow into said outer cavity;a means for rotating said fan structure;a means for providing particulate material above said fan structure; anda means for adjusting airflow into said outer cavity comprising a plurality of upper regulator members rotatably attached between said inner wall and said outer wall, wherein said plurality of upper regulator members each include a control arm that is attached to a common control cable that extends about an outer perimeter of said housing for allowing synchronous adjustment of the rotational position of each of said plurality of upper regulator members, wherein each said control arm is manipulated by said common control cable for rotating said plurality of upper regulator members;wherein said return opening includes a plurality of lower regulator members rotatably positioned along a common vertical axis;wherein said fan structure comprises a plurality of armatures, a plate attached to said plurality of armatures and rotatably supported within said housing, a plurality of lower blades attached to said plurality of armatures, and a plurality of upper blades attached to a distal end of said plurality of armatures.
