ABSTRACT:
In a device for separating a liquid, as a cutting oil, from a mixture of metal chips and larger pieces of metal, such as bar ends and scrap, there is provided structure for preliminarily separating larger pieces of metal from the entire mass prior to the separation of the oil from the chips. A centrifuge is provided having a drum with an intermediate perforated segment to permit the escape of oil therefrom while the chips move to the upper edge of the drum and thence outwardly to a receiving structure. A chute is provided for feeding the mixture to be separated into the central portion of the drum and a strong stream of air is caused to flow therethrough into the centrifuge. An opening is provided in the bottom of the chute intermediate its ends. Thus, bar ends, and other large pieces of metal which may be included in said mixture, will drop through the opening while air being drawn into the chute through the opening by the centrifuge will entrain the metal chips to prevent their dropping out of the opening and continue onward through the chute into the centrifuge.
