Abstract
The present invention is directed to a mist pump for a conveyor of a decanter centrifuge. The mist pump is incorporated into the feed chamber and prevents mist from leaving the feed zone and building up a layer of feed in the conveyor hub. The mist pump includes a plurality of vanes attached to, extending radially inward from and spaced about an interior surface of the sidewall of the feed chamber. The mist pump also includes a ring positioned coaxially about the longitudinal axis, attached to each of the pump vanes and spaced radially inward from the sidewall to provide a plurality of return openings defined by the ring and the sidewall.
