Abstract
A separation disc for a centrifugal separator and a method for manufacturing the separation disc are disclosed. The separation disc is of metal material and adapted to be compressed in a stack of separation discs inside a centrifugal rotor for separating a liquid mixture. The separation disc has a truncated conical shape with an inner surface and an outer surface and a plurality of spacing members extending a certain height above at least one of the inner surface and the outer surface for providing interspaces between mutually adjacent separation discs in the stack. The spacing members are of such small size that each one of them has a width which is less than 2 mm along the surface of the separation disc. The surface of the separation disc is configured with a distribution pattern of the small-sized spacing members, in such a way as to provide equidistant interspaces in the compressed disc stack.
