Abstract
A centrifugal separator for the separation a slurry into a light phase fraction and a heavy phase fraction including a rotatable shell having a cylindrical portion and a conical portion with a rotatable auger therein and a light phase opening at one end and a heavy phase opening at a second end sized to throttle the flow of light phase liquid and heavy phase liquid and sized in the cross-sectional area ratio of A/B so that the discharge from the separator will continue to be in the ratio of A/B regardless of throughput and in one form the separator has a second heavy phase opening in the cylindrical portion and in another form, an annular barrier vane on the auger blocking flow of liquid fraction toward the heavy fraction opening.
