ABSTRACT:
A method is disclosed of converting tangled ribbons of ductile machining scrap into a densified intermediate product useful for making metal powder. A collection of the scrap having a packing density less than 50 lbs/ft.sup.3 is subjected to impacting forces between weighted, freely moving elements and an anvil means for progressively flattening the scrap. The impacting is repeated to substantially flatten all of the scrap and reduce some of the ribbons by fatigue breakage to chips; the resulting processed scrap will have a packing density in excess of 90 lbs/ft.sup.3.
