Abstract
A classifying device having two or more classifying passages is provided, the classifying device including a first classifying passage to which particle dispersion liquid is fed; plural discharge ports provided in the first classifying passage, the plural discharge ports including a discharge port of coarse particle dispersion liquid and a discharge port of fine particle dispersion liquid; a second classifying passage; and a connecting passage that transports the coarse particle dispersion liquid to the second classifying passage, wherein the discharge port of the coarse particle dispersion liquid is provided in more upstream part of the first classifying passage than the discharge port of the fine particle dispersion liquid.
Claims20
A classifying device having two or more classifying passages, the classifying device comprising:
- a first classifying passage to which particle dispersion liquid is fed;
- a plurality of discharge ports provided in the first classifying passage, the plurality of discharge ports including a plurality of coarse particle dispersion liquid discharge ports and a fine particle dispersion liquid discharge port;
- a second classifying passage;
- and
- a plurality of connecting passages that transport coarse particle dispersion liquid to the second classifying passage from the first classifying passage via the plurality of coarse particle dispersion liquid discharge ports,
- wherein an average particle diameter of particles contained in the coarse particle dispersion liquid is larger than an average particle diameter of particles contained in the particle dispersion liquid fed to the first classifying passage,
- an average particle diameter of particles contained in fine particle dispersion liquid is smaller than the average particle diameter of the particles contained in the particle dispersion liquid fed to the first classifying passage, and
- the coarse particle dispersion liquid discharge ports are provided in more upstream part of the first classifying passage than the fine particle dispersion liquid discharge port.
A classifying method comprising:
- feeding particle dispersion liquid to a first classifying passage of a classifying device that includes a plurality of classifying passages;
- classifying particles contained in the particle dispersion liquid while transporting the particle dispersion liquid through the first classifying passage, wherein a plurality of discharge ports are provided in the first classifying passage, and the plurality of discharge ports includes a plurality of coarse particle dispersion liquid discharge ports for discharging coarse particle dispersion liquid and a fine particle dispersion liquid discharge port for discharging fine particle dispersion liquid;
- and
- transporting at least one discharge liquid discharged from any one of the plurality of discharge ports to a second classifying passage, wherein an average particle diameter of particles contained in the discharge liquid transported to the second classifying passage is larger than an average particle diameter of the particles contained in the particle dispersion liquid fed to the first classifying passage, and the coarse particle dispersion liquid is transported via a plurality of connecting passages that transport the coarse particle dispersion liquid to the second classifying passage from the first classifying passage via the plurality of coarse particle dispersion liquid discharge ports.
