Abstract

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.

Abstract

The present invention addresses the problem of dispersing or grinding particles more finely than conventional media-less dispersing/grinding devices. This dispersing/grinding device 10 is for dispersing or grinding particles in a particle-containing liquid, by utilizing the shearing force when the liquid passes through a gap S. The device comprises: a casing 11; a rotor 13; a stator 16; an impeller 14; and a drive means 15. The gap S is provided between the stator 16 and the rotor 13. When the drive means 15 rotates the rotor 13 and the impeller 14, the particle-containing liquid, which has entered from an inflow section 11a of the casing 11 due to the rotational force of the impeller 14, passes through the gap S. The particles in the particle-containing liquid are dispersed or ground as a result of the shearing force when the liquid passes through the space S.
