Title:
DISPERSING/GRINDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/190402
Kind Code:
A1
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.
