Transverse disc of a centrifuge screw, and solid-bowl screw centrifuge

A solid bowl screw centrifuge (10) with a centrifuge screw (30), comprising a screw hub (32) created of longitudinal bars (58) at least in some sections, wherein at least one transverse disc (60) is arranged within the screw hub (32) for stabilizing a screw hub structure (56),

• characterized in that
• 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 center point (M) and the transverse disc circumference (72),
• wherein recesses (90), which are arranged evenly distributed, are formed at the transverse disc circumference (72), whereby the recesses (90) serve to receive the longitudinal bars (58),
• wherein the at least one opening (70) includes one or more openings that are formed at least in some sections on all of the imaginary circle lines (71) of the transverse disc (60) and wherein independent of the pond depth (52) formed within the drum (16) of the solid bowl screw centrifuge (10), the transverse disc (60) forms across the entire diameter area of the transverse disc an axial passage for a centrate produced within the solid bowl screw centrifuge (10).
