Abstract

An electrostatic separator separates conductive particles from raw materials includes: a container with a raw material layer; a gas dispersion plate at the bottom of the raw material layer; at least one vibrating body in the raw material layer flush with the gas dispersion plate or above it; a fluidization gas supplier introduced from the container bottom into the raw material layer flows upward through the gas dispersion plate; an upper electrode above the raw material layer; a lower electrode in the raw material layer, the lower electrode being flush with the gas dispersion plate or above it; a power supply applies a voltage between the upper and lower electrode wherein one becomes a negative electrode, the other becomes a positive electrode, and an electric field is generated between them; and a capturer captures conductive particles that have flown out of the raw material layer surface toward the upper electrode.
