A vibratory conveyor for particles of tobacco or other bulk material has a trough with an elongated bottom wall the upper side of which merges smoothly into a downwardly sloping convex cylindrical or substantially cylindrical external surface of a tubular or like member forming part of the front portion of the trough. This ensures that fragments of dust (if any) which are being entrained by the particles of bulk material are less likely to be expelled or permitted to escape from successive increments of the flow of bulk material advancing beyond the bottom wall of the trough. Moreover, the particles of conveyed bulk material are more likely to remain in their prescribed path.
