Claim:
1. A centrifugal separator for separating a fluid mixture into components, comprising: a frame; a rotor which is rotatably supported in the frame around a rotational axis, which rotor forms within itself a separation space delimited by a rotor wall, and comprising a set of separation plates defining separation passages there between; an inlet extending into the rotor for supply of a fluid mixture to be separated in the separation space; a first outlet for a separated lighter first component of the fluid mixture extending from a radially inner portion of the separation space; a sludge space being defined as an annular portion of the separation space radially outside the separation plates; a second outlet for a separated denser second component of the fluid mixture extending from the radially outer portion of the sludge space; and a plurality of sludge space plates arranged in the sludge space and connected by connecting plates arranged in an axial direction, an inner edge of the sludge space plates being radially spaced from an outer edge of the separation plates, the sludge space plates extending perpendicular to the rotational axis and disposed perpendicular to the connecting plates, wherein the plurality of sludge space plates are spaced from one another in an axial direction with respect to the rotational axis, wherein the sludge space plates are separate components from the separation plates, and wherein a gap is formed between the sludge space plates and the rotor wall.
