摘要： A circulation type media agitator mill includes a cylindrical vessel, and an agitating member arranged rotatably in the cylindrical vessel. A grinding media is contained in a grinding chamber defined between a cylindrical wall of the agitating member and a surrounding cylindrical wall of the vessel. A media-separating member is arranged coaxial with the agitating member in the inner space of the agitating member. An inlet is provided for leading material to be ground to the grinding chamber, and an outlet leads the material separated from the grinding media to the outside of the mill via the media separating member. The vessel may have a length to diameter ratio smaller than one. The cylindrical wall and hub of the agitatihg member have openings to allow the grinding chamber to communicate with the media separating chamber.

摘要： A dispersing and grinding device for dispersing or grinding particles in a particle-containing liquid with a shear force generated when the particle-containing liquid passes through a gap, the dispersing and grinding device including: a casing; a rotor, a stator, and an impeller; and drive means. The gap is defined between the stator and the rotor. When the rotor and the impeller are rotated by the drive means, the particle-containing liquid is allowed to flow into the casing through an inflow portion of the casing by a rotating force of the impeller, and passes through the gap to cause the particles in the particle-containing liquid to be dispersed or ground with a shear force generated when the particle-containing liquid passes through the gap.

摘要： It is intended to, in a horizontal dry mill, prevent blow-up and adhesion of a raw material, etc., to a raw material input section. In a horizontal dry mill (10) of the present invention, a diameter of a raw material supply section (13) provided in a grinding tank (14) is set to be less than a diameter of a grinding chamber (12). Further, a diameter of a mechanical thrust generating device of the raw material supply section (13) is set to a small value according to the diameter of the raw material supply section. Furthermore, a gap (e1) between an outside dimension of a screw (26) as the mechanical thrust generating device and an inner diameter of the grinding tank (14) in the raw material supply section (13) is set between 0.5 mm and ⅓ of a diameter of each grinding medium M.

摘要： A media-agitation type pulverizer of the present invention includes: a guide ring installed to radially divide a lower region of a pulverization chamber into an inner section and an annular outer section. A flow of a mixture of a raw material slurry and pulverizing media is formed as a helicoidal flow comprising a secondary flow flowing through a circulation flow path which has an upward flow path and a downward flow path created, respectively, in the outer section and the inner section of the lower region of the pulverization chamber, with respect to the guide ring. A rotational-flow suppressing device is provided within the pulverization chamber and adapted to strengthen the secondary flow of the helicoidal flow, thereby stabilizing the helicoidal flow. As a result, a media-agitation type pulverizer is provided which is capable of creating a uniformized, stable helicoidal flow in a mixture of pulverizing media and a raw material slurry, without unevenness of a centrifugal force distribution, thereby performing pulverization/dispersion uniformly with satisfactory energy efficiency.
