Abstract
The static mixer contains a bundle of chambered strings (A, B, . . . ) which at least partly comprise mixing-active chambers (A1, A2, . . . ). The bundle is arranged in a tube. The mixing-active chambers extend in the direction of the tube in each case between two closed ends. Two mutually adjacent side walls of the mixing-active chambers contain four alternately disposed passages which produce connections to two chambers lying upstream and downstream. Re-layering chambers are arranged between at least two sections of the mixer which contain mixing-active chambers, each of which has two closed ends and three lateral passages to adjacent chambers. The re-layering chambers occur in pairs, with a direct or an indirect connection being provided via one of the passages in each case.
