Document Type and Number:
WIPO Patent Application WO/2024/057830
Kind Code:
A1
Abstract:
[Problem] To provide a method for grinding a cellulose polymer, the method being capable of stably producing a cellulose polymer that has a particle diameter of less than 50 µm. [Solution] A method for grinding a cellulose polymer by means of a bead mill 4, wherein: the average diameter of beads 16 that are used for the bead mill is 0.1 mm to 10 mm; the peripheral velocity of an agitator 14 of the bead mill is 2 m/sec to 15 m/sec; and the bead filling rate of the bead mill is 50 vol% to 90 vol%.
