Abstract

The static mixer apparatus for highly viscous media comprises a pipe (2) and at least one mixer element (10) arranged in the pipe. The pipe defines a principal flow direction (4) of the medium to be mixed. The structure elements of the mixer element are substantially webs (3, 30) each forming an angle relative to the principal flow direction. The cross-section of the pipe is not completely covered over by the mixer element, namely such that two segment-shaped edge regions lying between the side edges of the lateral webs (3) of the mixer element and the pipe wall do not have any webs (30) arranged inclined relative to the principal flow direction. Reinforcing ribs are disclosed for the static mixing element, which ribs can optimally have an expanded center section to cooperate with the mixer in producing mixing of the highly viscous media.
