  • Patent number: 6349638
    Abstract: A briquetting machine for compacting metal chips into briquettes with a movable die that provides plural die cavities. After metal chips are loaded into a loading chamber from a hopper, a chip compacting ram pushes the chips at a high speed and low pressure into one of several bores, disposed within a sliding die gate, and against an endplate. The bore and endplate together constitute a die and define at least two die cavities. After the ram reaches a predetermined low pressure, the ram then proceeds at a relatively low speed and relatively high pressure to compress the chips within the die into a briquette. Upon reaching a predetermined compaction pressure, the ram retracts from the bore. After such time, the die gate is moved to a location where one bore lies before an ejector cylinder. The ejector cylinder then extends into the bore, expelling the briquette from the bore.
