Abstract
A static mixer includes profiled layers which are arranged in a ring space and which contain mutually crossing flow channels which are inclined relative to a central axis. A fluid mixture is to be transported in the axial direction in the presence of a mixing action. Each layer extends over a surface which forms a closed or largely closed periphery transverse to the axis. Each layer comprises equivalent channels which extend on an inner or outer side of the layer over at least approximately equally long distances from a first to a second cross-section of the ring space, so that each channel imposes an azimuthal velocity component onto the fluid mixture which flows through it which is substantially equally large for all equivalent channels.
