Abstract: A separator for material which includes components of different specific gravities and sizes, includes a series of spaced, parallel shafts disposed in essentially the same plane, which may be tilted upwardly. A series of non-circular discs, such as elliptical, three lobed, etc., are mounted on each shaft and interspaced with the discs on adjacent shafts. A pipe, on which the discs are mounted, or a spacer mounted on the shaft provides circular surfaces between the discs which clear the projections of the discs of adjacent shafts but when the disc surfaces between the projections come opposite the pipe or spacer, cause holes or spaces to be produced, through which material may fall, if sufficiently small. As the discs rotate, they not only cause the holes to open and close, but also propel the material both upwardly and forwardly. The discs may be mounted on a shaft in a spiral relation, so that not only is the material pushed upwardly and forwardly, but also laterally.
