Fine particle separation method for dispersion liquid, involves providing electric charge opposite to electric charge of fine particle, to outer circumferential surface of rotator rotated to absorb fine particles

摘要

A rotator (4) is installed in the fine particle dispersion liquid and an electric charge opposite to electric charge of fine particles is applied to the rotator outer circumferential surface. The rotator is rotated and its outer circumferential surface is made absorb the fine particles in the dispersion liquid.
