  • Centrifugal separator having an improved flow and system comprising such a centrifugal separator
    Patent number: 11938489
    Abstract: A centrifuge (1) for separating intermixed particulate material of different specific gravity. The centrifuge (1) comprising a centrifuge bowl (10) having a plurality of annular recesses (19), a housing (30), an inlet (17), and means for rotating the centrifuge bowl (10) about the central axis (15). An annular cavity (31) is defined between the housing (30) and the centrifuge bowl (10). The annular cavity (31) is fluidly connected to the plurality of annular recesses (19) on the inner surface of the centrifuge bowl by a number of perforations in the centrifuge bowl wall (12). The annular cavity (19) has a fluid inlet to provide fluid into the annular cavity. The annular cavity (19) has an accumulated cross-sectional flow area (Aflow) at two different heights in the annular cavity that differs by at least a factor 10.
