Abstract
A centrifugal separator (14) comprises a stationary frame (15), a spindle (16) rotatably supported by the frame, a centrifuge rotor 17 mounted to a first end of the spindle to rotate together with the spindle around an axis (X2) of rotation. A stack (10) of separation discs (1) is arranged to rotate coaxially with the centrifuge rotor The stack of separation discs comprises a set of axially aligned separation discs with an inner surface and an outer surface and a plurality spot-formed spacing members extending from a base from at least one of the inner surface and the outer surface The surface density of said spot-formed spacing members is above 25 spot-formed spacing members/dm2 throughout the inner and/or outer surface of the separation disc. A first region at a bottom of the discs has a higher density of the spot-formed spacing members than a second region.
