Abstract:
A static mixing element for mixing at least two components, comprising:a) a mixing channel of substantially tubular shape which is undivided in axial direction and is formed by at least two separate radial segments and wherein an inner wall of said mixing channel in radial direction forms an outer boundary of a cross section for receiving said components; and b) mixing vanes arranged in said mixing channel which radially abut on said inner wall of said mixing channel and which are formed by at least one element which is separate from said mixing channel, wherein said mixing vanes comprise a last mixing vane which is arranged axially in flow direction at a last position of said mixing vanes and at least one second mixing vane which is arranged axially in flow direction before said last mixing vane, and wherein at least one of said at least one second mixing vane is, in an area where it radially abuts on said inner wall of said mixing channel, interconnected with said inner wall for transferring axial forces to said mixing channel by protruding into a recess in said inner wall of said mixing channel, wherein said recess substantially has the shape of said mixing vanes in said area.
