PURPOSE:To obtain a uniform dispersion in liquid by a method wherein a hopper is used as a plurality of split hoppers when causing a liquid-swellable powder (powder in the hopper to pass through a dispersing machine by a vibrating feeder so as to disperse the powder into the liquid. CONSTITUTION:The powder in a plurality of fixed hoppers 1 is fed into the vibrating feeder 4 through discharge valves 3 of discharge ports 2 and flexible tubes 5. The feeder 4 fluidizes the powder and feeds it into the dispersing machine 11. The powder thus fed is dispersed into water by the dispersing machine 11. Accordingly, since the powder does not undergo caking, adhering of particles with each other is avoided and a uniform dispersion liquid can be obtained. |
