Abstract
Simple, flow regulating tap-off means are provided in the bottom of a helical eluent supply conduit which is co-axial with a helical separator sluice in a gravitational separator. The tap-off means is an insert in the floor opening of the eluent conduit having an aperture in the insert and an inner lip at the top of the insert that does not extend above the floor of the eluent conduit. A portion of the inner lip is broken away to facilitate directing the eluent to flow through the aperture. Rotating the insert varies the amount of the broken away portion in contact with the downward flowing eluent which in turn regulates the amount of eluent flow through the aperture.
