A cleaning and sorting machine for removing particle trash, such as dockage, from desired larger particulate material of substantially uniform size, employs an elongate and generally cylindrical driven separating drum having a screen periphery of a predetermined mesh, for retaining the desired larger particles. The drum, mounted on a horizontal axis, has mounted therein a series or multiplicity of stationary slide baffles with peripheries of said baffles in spaced relation to the inner periphery of the drum and the baffles are declined from their upper portions to their lower portions in the direction of discharge of the machine, and constitute the only means for moving or progressing the particulate material from the entrance at one end of the drum to the discharge at the other end. The screen successively lifts particles over a substantial segmental area of the drum and thereafter, with gravity, dropping all particulate material upon the baffles with attendant rolling and sliding action and the said declined baffles are preferably densely perforated with sieve-like apertures of substantially the mesh of the drum screen to constitute a further separation step in the progress of all particulate material through the machine.
