ABSTRACT:
Displacement washing of slurry body is provided in a centrifuge filter (peeler centrifuge) by introducing wash liquid along the inner surface of the drum while the drum is rotating. The wash liquid moves through the filter into the slurry body in a broad front to displace the mother liquor of the slurry body toward the axis of rotation of the drum. The mother liquor is removed by an overflow pipe or dip tube to a point outside the centrifuge filter for disposal.
