Abstract

A gravity circulation mixer for bulk goods including a mixing container in which the bulk goods are divided into two quantity flows. After having recombined the two individual quantity flows of bulk goods in a mixing bowl, it is conveyed via a vertical ascending pipe and a gravity pipe back into the mixing container. The gravity pipe is arranged at an angle with respect to the ascending pipe and extends downwardly into the mixing container. The connection between the ascending pipe and the gravity pipe is constituted by a baffle portion so that the upwardly conveyed bulk goods are deflected at the baffle portion and caused to fall into the mixing container.
