Abstract: A rotatable wood chip thickness classifying device. The apparatus includes two coaxial, spaced sets of apertured discs, each set defining a drum. The interdisc spacing of each drum is uniform, each drum having a different interdisc spacing from the other drum. For each set of discs, the inside diameter of adjacent discs alternates. Wood chips are fed into the interior of the first drum, this drum having a typical disc interspacing of 2 mm. The common axis of drum rotation is slightly tilted to the horizontal and chips of less than 2 mm fall through the interdisc openings of the first drum. The remainder of the chips pass to the interior of the second drum, typically of 8 mm interdisc spacing. Chips less than 8 mm fall through the interdisc openings of the second drum. The alternation of inside disc diameters, for each drum, yields a chip tumbling effect to thereby inhibit an elongated chip, of a diameter of less than 2 mm for example, from straddling the 2 mm openings and not falling therethrough.

Abstract: A rotating drum (1) for cooling and separating castings and molding sand has a foraminous liner (27, 8). In a first part (28) thereof there are sand raising vanes (17) between this liner (27) and the closed wall (28) of the drum to raise sand, passing through the perforations in this liner part (28) to spray it over the castings. In a second, more downstream part (8) of the liner this liner part (8) intersects the theoretical sand level (13, 14) to lift the castings from the sand, so as to discharge the castings via liner part (9) and discharge edge (10) separately from the sand. The sand separated from the castings is taken up in a closed end part (5, 7) of the drum (1) having a discrete discharge edge (11) for discharging the sand at the downstream end in a narrow zone. This gives a drum with high cooling and separating capacity and efficiency with the least possible noise and dust generation.
