Full Title

Flow mixers; Mixers for falling materials, e.g. solid particles (centrifugal mixers B04) > Static mixers (colloid-mills B02C; mixing valves F16K11/00) > in which the mixing is affected by moving the components jointly in changing directions, e.g. in tubes provided with baffles or obstructions > Mixing tubes, e.g. wherein the material is moved in a radial or partly reversed direction > Mixing tubes wherein the shape of the tube influences the mixing, e.g. mixing tubes with varying cross-section or provided with inwardly extending profiles
