Abstract

The present invention provides a separation disc (1) for a centrifugal separator, said disc being adapted to be comprised in a stack of separation discs inside a centrifugal rotor for separating a fluid mixture. The separation disc (1) has a truncated conical shape with an inner surface (2) and an outer surface (3) and a plurality of spacing members (4) extending from at least one of the inner surface and the outer surface. The spot-formed spacing members (4) are for providing interspaces between mutually adjacent separation discs in a stack of separation discs. The separation disc (1) further comprises at least one elongated rib (36) extending from the inner surface to a height (h) that is less than the height (H) to which said plurality of spacing members extend. Further, at least one elongated rib (36) extends from first position on the inner surface (2) to a second position on the inner surface, wherein the second position is at a radial distance that is larger than the radial distance of the first position, and the relation between the height of the elongated ribs (h) and the spacing members (H) are h/H > 0.5.
