Document Type and Number:
WIPO Patent Application WO/2022/119087
Kind Code:
A1
Abstract:
The present invention relates to a horizontal bead mill for dispersing secondary battery material, the horizontal bead mill comprising: a vessel which has an inlet and outlet for a dispersion medium formed, and of which the inside is filled with beads; a rotor which rotates in the vessel so as to rotate the beads so as to disperse the dispersion medium; and a drive unit which rotation-drives the rotor, wherein the inner surface of the side wall of the vessel is formed into an inclined section which is inclined by a predetermined angle with respect to a shaft of the rotor and is formed so that, compared to the inflow side inner diameter of the vessel, the outflow side inner diameter thereof gradually decreases.
