Abstract

The invention relates to a separating body which can be set into rotation to separate solid or liquid particles of micron or submicron size from a fluid, wherein the body has a large number of separating ducts with singly connected walls over a substantial part of the axial length, where the walls of at least one of the separating ducts are not parallel to the axis of rotation. The tangent of the angle between the tangent planes of the walls of the separating duct and the axis of rotation is designated with tan .alpha., the radial width of the separating duct is designated with d, the length of the separating duct is designated with L and the rotation speed of the separating body is designated with .OMEGA. where these variables are chosen in mutual dependence in a manner such that the dimensionless number (.OMEGA.Ld tan .alpha.)/.nu. is located over a substantial part of the separating duct in the range up to 192, wherein .nu. is the kinematic viscosity of the fluid. The invention further relates to a separating unit provided with at least two separating bodies.
