Abstract: An improved mixing column for mixing a plurality of liquid or paste-like components of a material has several tiers having at least two flow-division chambers which overlap each other at least partially, and where each of these superimposed flow-division chambers has a flow-division wall which divides the incoming fluid. A different passage opening of the tier is connected with each of the superimposed flow-division chambers. The flow-division chambers are connected to mixing chambers arranged on either side thereof. Successive tiers are oriented at 90.degree. with respect to each other and each successive tier is shifted an additional 90.degree. in the same direction of rotation such that the mixing chambers of a lower tier are in communication with the passage openings in the floor of the adjacent upper tier. In this way, improved mixing of the components is achieved with a more compact construction as well as simplified manufacture.
