Abstract

The subject of the invention is a dynamic mixer for viscous compositions, in particular for components for dental impression compounds. The mixer consists of a mixer tube, a rotor located in the latter, and an end wall with inlet openings through which the components to be mixed pass into the mixer. In doing so, they first alternately fill chambers arranged on the rotor. The composition then flows out of the chambers through admission openings into the mixing channel, where it can be stirred by mixer blades.
