Abstract: The invention relates to a centrifugal screw (10) comprising a substantially tubular screw hub (15) and a screw flight (20), wherein at least some portions of a root (21) of the screw flight (20) are attached directly to the tubular screw hub (15). According to the invention, rods (30) are formed between at least two turn portions (25) in the longitudinal direction (R) of the centrifugal screw (10), said rods (30) being entirely or nearly entirely located at a distance from the screw hub (15).

Abstract: The present invention relates to a screw hub (70) for a centrifuge screw which extends along a longitudinal axis and has at least one longitudinal portion (72) having an opening structure (74), wherein the opening structure (74) is formed by a plurality of connecting elements (75) which delimit a plurality of openings (77) for the passage of a medium, in particular a two-phase mixture, wherein the connecting elements (75) are arranged radially outside on the longitudinal portion (72) relative to the longitudinal axis and form a periphery of the longitudinal portion (72), two connecting elements (75) in each case forming a connecting piece pair (81) that delimits at least one opening (77), both connecting elements (75) of the connecting piece pair (81) extending in the longitudinal direction and crosswise to the longitudinal direction, or a first connecting element of the connecting piece pair (81) extending in the longitudinal direction and a second connecting element of the connecting piece pair (81) extendi

Abstract: The invention relates to a transverse disc (60) of a centrifuge screw (30) for stabilising a screw hub structure. According to the invention, at least one opening (70) is formed at least in some sections on at least 75% of all the imaginary circle lines (71) of the transverse disc (60) between the centre point (M) and the transverse disc circumference (72).
