Air separator system

Abstract

An air separator system for separating particulate material into coarse and fine particles without utilizing water. The inventive device includes a trailer, a support frame pivotally attached to the trailer, a tapering body having an outer wall and an inner wall, a motor secured to the body, a funnel connected to a center tube rotatably attached within the body, and a fan structure attached to the lower portion of the center tube for agitating and blowing upon particulate material that enters the funnel from a feed conveyor. A plurality of upper regular members are pivotally attached within the upper portion of the outer cavity created between the outer wall and the inner wall for adjusting the amount of air flow into the outer cavity. A plurality of lower regulator members are attached within the inner wall for allowing the air to return upwardly toward the fan structure during operation to lift the lighter particulate material. The fan structure is preferably comprised of a lower plate spaced below the lower opening of the center tube, a plurality of upper blades extending into the outer cavity, and a plurality of lower blades within the inner cavity. The upper blades are preferably larger in size than the lower blades. In operation, the fine material is lifted upwardly toward the outer cavity where it is eventually dispensed through a lower outer discharge nozzle. The coarse material falls into the inner cavity defined by the inner wall where it is eventually dispensed through an inner discharge nozzle separate from the fine material.
