A vibratory feeder for feeding particulate material comprises an elongate tray structure which is vibrated to cause particulate material to slide along it toward the discharge end of that structure. The tray structure includes a section comprised of a series of steps extending transversely across it at successively diminishing heights with gaps between the steps so that particles below a certain size can fall through the gaps whereas larger particles bounce across the steps towards the discharge end of the tray structure. |
