  • Nozzle separator bowl
    Patent number: 10507473
    Abstract: The invention relates to a centrifugal separator bowl (4) for a nozzle separator (1). It is primarily characterized in that the bowl (4) is manufactured from one single piece and has an interior comprising pyramidal wall openings (12) pointing to openings (10) for the nozzles (11). The invention further relates to a centrifugal separator (1) using such centrifugal separator bowl (4). With such design a treatment of suspensions with high specific gravity, including of up to 2.0 and beyond is possible.

  • Discharge Nozzle for Nozzle Separator
    Publication number: 20160001303
    Abstract: The invention relates to an outlet nozzle assembly (10) for use with a rotor of a centrifuge, especially for a nozzle separator (1), consisting of a cylindrical nozzle holder (11) to be mounted into a bore (12) in the bowl (4) of the centrifuge (1), a nozzle (13) to be fixed to the nozzle holder (11) and a wear tube (14) fitted into the nozzle (13). It is mainly characterized in that the nozzle (13) is mounted from the outside to the nozzle holder (11), the nozzle (13) has an axis (21) arranged in an acute angle (?) to the normal to the axis (20) of the bore (12) in the bowl (4) and that the opening (23) to the nozzle (13) is arranged asymmetrically in the nozzle holder (11), i.e., at a distance from the axis (20). With such a design high concentrated mineral suspension can be treated in a centrifuge (1) to separate different fractions of solids.
