Abstract
A static mixer includes a plurality of mixing chambers for mixing at least two flowable components. The mixing chambers are arranged one behind the other as well as adjacently in a tube along a tube axis. The mixer includes basic mixing chambers and modified mixing chambers. Basic mixing chambers are bounded off from one another by radial walls oriented in the direction of the tube axis and by end walls transverse to the tube axis. Apertures in the radial walls form inputs and outputs between adjacent chambers for the components to be mixed. Modified mixing chambers have structural modifications relative to the basic mixing chambers. In one embodiment, the modification includes adding inclined walls. In another embodiment, the modification includes changing the longitudinal dimension of the chamber relative to the basic mixing chamber.
