Title:
WET CLASSIFIER AND WET CLASSIFICATION METHOD THEREOF
Document Type and Number:
Japanese Patent JP2011125801
Kind Code:
A
Abstract:

To provide a wet classifier that further reduces the particle size (separation diameter) of 50% fractional separation efficiency when fine particles are classified, and to provide a wet classification method using the classifier.

The wet classifier has an electric field mechanism for applying an electrostatic field to particles in slurry, and is desirably a liquid cyclone. The electric field for applying the electrostatic field to the particles is desirably ≥70 V. In the wet classification method using the wet classifier, the slurry containing the particles is subjected to distributed processing, and classification processing is performed within 15% rate of change for zeta potential immediately after the distribution. It is preferable that a bead mill is used for the distributed processing.
