Abstract: In the case of a rotor (109) for a device for mixing powder and liquid, a number of connecting arms (203) are formed, as a connecting structure, between an outer blade carrier plate (215), which is equipped with outer blades (127), and a shaft receptacle (117), between which connecting arms there are situated liquid outlet regions (206). This has the result, owing to a relatively high throughput with a shear action which is still sufficient, of a relatively high mixing rate and of a relatively low tendency for powder to agglutinate.

Abstract: In the case of a rotor (109) for a device for mixing powder and liquid, which device has a stator which interacts with the rotor (109), at least some shear blades (124) are of wedge-shaped form and are inclined with one face side (233) in a flow direction (239). This has the result, in the case of an effective diversion at side walls (227) situated at the front in a flow direction (239), of an intense shear action at the face sides (233) and of a relatively low risk of formation of deposits and adherent accumulations on the side walls (230) situated at the rear in the flow direction (239).

Abstract: A mixing apparatus having a mixer unit (7) which includes a cup-shaped stator (24, 33) and a rotor (17) located in the mixing chamber (18). Two inputs (6, 8) and an output (13) are provided. The mixing chamber (18) is divided into a plurality of mixing regions by a separating disc (20). Inner blades (21) and outer blades (22) are provided. An edge rail (37) is positioned in the plane of the separating disk (20), between the inner (21) and outer (22) blades. The stator (24, 33) has a different configuration in the various mixing areas of the mixing chamber (18). As a result, different yield and mixing ratios can be obtained in the mixing areas of the mixing chamber (18).

Abstract: A device for dispersing, emulsifying or suspending gases, liquids or granular substances, more particularly for wetting and dispersing powders in liquids, includes a disc-shaped rotor (8) in a dispersing chamber (7), with two substance inlets (72, 76) and one product outlet (11). Each substance inlet (72, 76) preferably has axial duct portions (75, 83, respectively) disposed on each side of the rotor (8). The two substance streams are arranged to bring together the substances in the outer edge region of the rotor disc (67). The product outlet (11) is at an outer edge of the dispersing chamber (7).

Abstract: A process and an apparatus are specified by which emulsions or suspensions of both different and changing composition can be separated in a particularly reliable manner. Proceeding on the principle of turbo-flotation, which is known per se, according to one embodiment, the gas is dispersed in the lower region of the vessel so that it is finely dispersed directly at the point where the emulsion is broken up or the suspension is separated, respectively, mechanically. Furthermore, the emulsion or suspension to be separated is supplied to the vessel close to the surface of the emulsion and the residue is removed at the bottom of the vessel. In this way, in continuous operation, a counter-flow between gas or gas/liquid suspension and emulsion can be achieved, thereby avoiding recontamination and re-emulsification. A strictly separated turbulence zone and a superposed flotation zone are formed. Foam carrying the flotate is formed on the surface.

Abstract: The invention is concerned with a device for the mixing and dispersion of at least two media, the device consisting of a substantially tubular stator (4) with at least one substantially axial inlet (12) and a substantially axial discharge (15) for the media and a rotor (2) with several radially extending rotor blades (5), the rotor being arranged in the stator (4), coaxially to it, between the inlet (12) and the discharge (15). In order that a partial stream of the media, which are at least premixed, be dispersed reliably, the stator (4) has radial openings (16) in the region of the rotor (2).

Abstract: A vertical axis dispersion turbine is of the type which has a stator consisting of a stator tube with a cylindrical guide ring of larger diameter than the tube defining an annular inlet, an axial rotor shaft freely rotatable in the stator tube and having several blades in the guide ring to draw a medium to be mixed and dispersed downwardly through the annular inlet, and dispersion means through which the medium flows. The dispersion means consists of a dispersion element mounted on the guide ring in a plane transverse to the rotor shaft, either immediately above or below the rotor blades, or two dispersion elements above and below the rotor blades. The dispersion elements are axially adjustable, and may consist optionally of radial arms, or a grid with axial openings or a perforated plate with axial passages. The guide ring is slidably adjustable on the stator tube.
