ABSTRACT:
A process and apparatus is disclosed for treating titanium machining scrap to remove both magnetic and non-magnetic high density inclusions, particularly bits or pieces of tungsten carbide broken from the cutting tool or tools associated with the scrap. In the process and apparatus a major portion of the undesired high density inclusions are removed by the novel use of an air separator, particularly one having an inclined, vibrating, air-conducting deck onto which the work product is fed and through which an upward current of air is blown. One or more magnetic separators are also used in advance of a final x-ray inspection station. The overall efficiency of the process and apparatus is such that a high percentage of initial input material is converted to high quality material passing the x-ray inspection and suitable for use in making rotating aircraft parts or other parts subjected to severe service demands.
