A vibratory apparatus is provided to dislodge and separate foreign matter from castings. A curved, bottom, supporting surface for the castings is inclined downwardly towards an outlet. Vibration imparting apparatus cause individual castings to travel up the curved portion and tumble over themselves as they simultaneously advance towards the outlet. Foreign matter, separated from the castings, is diverted away from the hopper as the castings progress continuously between the inlet and the outlet in a helical path.
