Abstract
Apparatus for mixing a powdered material with a liquid that includes a housing in which a working space having an inner wall is arranged and a rotatably-driven rotor being arranged in the working space. The rotatably-driven rotor includes a blade ring and bars, which are pointing toward the inner wall and are arranged at different positions in a circumferential direction of the rotor. The apparatus also includes a feed opening for the powdered material being arranged above the blade ring and an annular gap connectable to a liquid supply arrangement being arranged below the blade ring. In a direction parallel to an axial direction of the rotor, the bars one of connect to one another or overlap one another.
Claims20
An apparatus for mixing a powdered material with a liquid, comprising:
- a housing in which a working space having an inner wall is arranged;
- a rotatably-driven rotor being arranged in the working space, the rotatably-driven rotor comprising a blade ring and bars, which are pointing toward the inner wall and are arranged at different positions in a circumferential direction of the rotor and at different positions along an axial direction of the rotor;
- a feed opening for the powdered material being arranged above the blade ring;
- and
- an annular gap connectable to a liquid supply arrangement being arranged below the blade ring,
- wherein adjacent bars in the axial direction of the rotor one of connect to one another or overlap one another in the axial direction, so that, in rotation, axial extents of the adjacent bars overlap each other in the axial direction.
A apparatus for mixing a powdered material with a liquid, comprising:
- a housing in which a working space having an inner wall is arranged;
- a rotatably-driven rotor being arranged in the working space, the rotatably-driven rotor comprising a blade ring and bars, which are pointing toward the inner wall and are arranged at different positions in a circumferential direction of the rotor;
- a feed opening for the powdered material being arranged above the blade ring;
- and
- an annular gap connectable to a liquid supply arrangement being arranged below the blade ring,
- wherein, in a direction parallel to an axial direction of the rotor, the bars one of connect to one another or overlap one another, wherein the housing further comprises:
- an outlet at a bottom end of the working space, wherein a bottom edge of a bar adjacent to the outlet is flush with the bottom edge of the working space, and
- an outlet section connected to the outlet.
A method for mixing a powdered material with a liquid, comprising:
- supplying the powdered material into a working space having an inner wall;
- distributing the powdered material onto the inner wall via a blade ring arranged within the working space;
- wetting the powdered material below the blade ring with the liquid;
- and
- intermixing the powdered material with the liquid via bars radially extending toward the inner wall from a rotor arranged within the working space,
- wherein the radially extending bars are axially positioned along the rotor and circumferentially positioned around the rotor so that, adjacent bars in the axial direction of the rotor one of connect to one another or overlap one another in the axial direction, and so that, in rotation, axial extents of the adjacent bars overlap each other in the axial direction, whereby for the axial extent of the radially extending bars, there is virtually no region in the axial direction in which the powdered material is not impinged by the bars.
