Full Title
Full titles differ between systems:
Mixers with rotary stirring devices in fixed receptacles; Kneaders > Mixers with stator-rotor systems, e.g. with intermeshing teeth or cylinders or having orifices > with means for moving the materials to be mixed axially between the surfaces of the rotor and the stator, e.g. the stator rotor system formed by conical or cylindrical surfaces
Mixers with rotary stirring devices in fixed receptacles (magnetic mixers B01F33/45); Kneaders > Mixers with stator-rotor systems, e.g. with intermeshing teeth or cylinders or having orifices (the stirrers having a central axial inflow and a substantially radial outflow B01F27/81) > with means for moving the materials to be mixed axially between the surfaces of the rotor and the stator, e.g. the stator rotor system formed by conical or cylindrical surfaces
