Abstract
A circulation mixer for bulk material includes a container with funnel-shaped bottom to which a cellular wheel sluice is attached. The sluice is provided with inlet ports for bulk material as well as outlet ports communicating with pertaining riser pipes and includes a cellular rotor which conveys bulk material introduced through the inlet ports to the outlet ports for returning bulk material via the riser pipes to the upper part of the container. For pneumatically raising the bulk material through the riser pipes, air is injected through further ports which are arranged opposite the outlet ports and serve also as discharge ports for bulk material.
