In the mechanism for supplying waste metal cuttings from machine operations to a centrifuge having air suction means for separation and recovery of the cutting oils, a driven paddle-wheel type feed gate is provided in an inclined, gravity operated feed conduit for both maintaining a generally uniform rate of feed to the centrifuge and for serving as a barrier against the entry of air through the infeed end of the conduit. An air aspiration port is provided adjacent to and on the centrifuge side of the paddle wheel through which large metal chunks are discharged by gravity while smaller cuttings are entrained by the incoming air stream and transported past the port to the centrifuge. The bottom of the conduit at the feed gate is movably mounted to permit the passage of large, chunky material and means are provided to assure discharge of long pieces of material.
