Abstract
A mixer for viscous liquids and masses has a stationary first housing of circular cross section preferably disposed horizontally with inlet and outlet means for the material to be processed and surrounding a driven inner coaxial rotatably mounted second housing. The annular space jointly limited by the two housings with closing portions disposed on the faces contains a number of axially parallel mixer shafts driven in the same direction and disposed in a ring which perform a common revolving motion about the longitudinal axis of the housing. The mixer shafts extend with their envelopes as far as the inner and outer walls of the two housings leaving small gaps free. The mixer shafts formed as screw conveyors at least in portions are combined into meshing groups.

A mixer for viscous liquids and masses having a housing, the housing having a circular cross section and feeding and removing means for the material to be processed and a number of axially parallel mixer shafts driven in the same direction, the mixer shafts being disposed in a ring within the housing and arranged to perform a common revolving motion about the longitudinal axis of the housing, each mixer shaft defining an elongated cylindrical envelope of space in which the shaft rotates, the mixer characterized in that a first housing first housing unit surrounds an inner coaxial second housing unit, one of the two housing units being stationary and the other being mounted rotatably and driven, the housing units have opposed, closed ends, and are positioned so as to define an annular space therebetween, and the mixer shafts are disposed longitudinally in the annular space to rotate and arranged into meshing groups wherein the envelopes of the mixer shafts forming each meshing group at least partially overlap so as to form screw conveyors and the meshing groups are spaced apart so that the adjacent mixer shaft envelopes of adjacent mixing groups are spaced apart from each other.
