Abstract
An air classifier drum for receiving mixed materials and separating them into light and heavy materials, the heavy materials being dropped from one end of the drum during operation onto a conveyor, the drum being rotatable about an axis disposed at a selected angle to the horizontal and being vertically adjustable to the selected angle, the conveyor being vertically adjustable with the drum so that it will be constantly retained at a reasonably close-spaced relation to the drum to assure minimum impact of the heavy materials on the conveyor as they are discharged from the drum.
