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 by a centrifuge. The structure includes a chute for feeding the mixture to be separated into the centrifuge, and a strong stream of air is caused to flow through the chute into the centrifuge. An opening is provided in the bottom of the chute intermediate its ends such that bar ends and other large pieces of metal which may be included in said mixture will drop through the opening, while air being drawn by the centrifuge into the chute through the opening will entrain the metal chips to prevent their dropping out of the opening and carry them onward through the chute into the centrifuge. A movable gate responsive to the presence in the chute of pieces of metal too large to otherwise drop through the opening is provided for temporarily increasing the size of the opening sufficiently to permit such pieces to drop through the opening.
