There is provided an apparatus which can simplify, expedite and enhance the segregation of undesirable particles from desirable particles in a multiple-layer flow wherein the desirable and undesirable particles are randomly intermixed with each other. This is accomplished by a stepwise reduction of the thickness of the flow to thus locate all or nearly all undesirable particles at or close to the exposed sides of the resulting relatively thin flow so that the undesirable particles can be readily detected and segregated from the thin flow. The stepwise reduction of thickness of the original flow is effected by a cascade of successive accelerating conveyors including a first conveyor which receives successive increments of the original flow from a vibratory trough, and a faster second conveyor which receives successive increments of the accelerated flow from the first conveyor and cooperates with an overhead conveyor to define a channel for advancement of the repeatedly accelerated original flow into the range of instrumentalities for detection and segregation of undesirable particles.

A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall. Three structural features of the feeder reduce the tendency of material to jam between the drive rotor and the housing or other stationary parts. First, the distance between the circumferential edges of the drive disks and the housing inner wall increases from the inlet to the outlet in the direction of rotation of the drive rotor. Second, a low-friction brush seal disposed on the periphery of the drive disks seals the area between the periphery of the drive disks and the inner wall. Finally, a materials scraper having a flexible tip is mounted in the housing and extends into the drive rotor between the drive disks.
