  • Patent number: 7883036
    Abstract: The containment wall of a basket media mill is constructed of a sintered porous metal having porous openings each of a pore size less than the predetermined size of the media for confining the media within the bed in the basket as feedstock is passed through the porous openings in the containment wall. The containment wall extends over an overall area and the porous openings provide an open area through which the feedstock flows as the feedstock passes through the containment wall, and the open area is at least about twenty-one percent of the overall area of the containment wall for enabling a concomitant increased volumetric flow of feedstock through the containment wall. A substantially flat sheet of sintered porous metal having porous openings is formed into a cylindrical configuration to construct a cylindrical containment wall with porous openings each increasing in pore size from the interior of the cylindrical wall toward the exterior of the cylindrical wall.

  • Patent number: 7828234
    Abstract: The containment wall of a basket media mill is constructed of a porous synthetic polymeric material having porous openings each of a pore size less than the predetermined size of the media for confining the media within the bed in the basket as feedstock is passed through the porous openings in the containment wall. The containment wall extends over an overall area and the porous openings provide an open area through which the feedstock flows as the feedstock passes through the containment wall, and the open area is at least about fifteen percent of the overall area of the containment wall for enabling a concomitant increased volumetric flow of feedstock through the containment wall. A substantially flat sheet of porous synthetic polymeric material having porous openings is formed into a cylindrical configuration to establish a cylindrical containment wall with porous openings each increasing in pore size from the interior of the cylindrical wall toward the exterior of the cylindrical wall.

  • Patent number: 7784722
    Abstract: A stirring or dispersing device (1), has a hermetically sealed mixing chamber (5), a tool (2), and a drive mechanism (4) located outside of the mixing chamber (5). The tool (2) can be driven around a central shaft in the mixing chamber (5) which has a rod-shaped element (3) for force transmission from the drive mechanism (4) to the tool (2). The rod-shaped element (3) is connected at the entry to the mixing chamber (5) with a diaphragm (6), which is a part of the wall (7) of the mixing chamber (5), and the rod-shaped element (3) can be put into a wobbling movement by the drive mechanism (4), so that its end located in the interior of the mixing chamber (5) performs a rotating movement. The tool is constituted by a number of grinding elements (22) or balls to be introduced into the mixing chamber (5).
