Abstract: Manufactured goods such as cast components to which molding sand is still adhering, are treated in a vibratory conveyor chute for cleaning and cooling the goods. As the goods travel down the chute they are exposed to force components extending perpendicularly and across to the travel direction along the length of the chute. These force components impose on the goods a revolving motion along a helical path. This revolving motion may be improved or intensified by directing the resulting force components (R, R') of the force causing the revolving motion to extend at a spacing from a so-called "center of gravity line" (S, S') defining or interconnecting the center of gravity points along the length of the vibratory chute system. This spacing causes a distribution of the goods (11) in the chute such that the goods (11) have a slanted surface (10) in the chute (1). Thus, the vertical acceleration values (k.sub.v) are larger at the upper return zone 26 than they are at the lower return zone 27.

Abstract: The present conduit or trough for a vibratory conveyor is constructed especially for transporting and/or treating bulk materials such a wood chips or the like. The trough or conduit is provided inside thereof with partition plates extending substantially across the transport direction. These partition plates take up part of the depth of the trough or conduit and may be arranged at an angle relative to the transport direction. Baffles may be arranged in the conduit or trough to extend away from the partition plates and substantially in the transport direction.
