  • Patent number: 11986839
    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.

  • Patent number: 11944983
    Abstract: An electrostatic separation method includes: applying voltage between a lower electrode at a bottom portion of or in the raw material layer and an upper electrode above the raw material layer, generating an electric field between electrodes; fluidizing the raw material layer and bringing conductive particles and the lower electrode into contact in the raw material layer charging only the conductive particles wherein their polarity becomes the same as the lower electrode; generating polarity, the same as the upper electrode, by dielectric polarization on a conveyor belt downward-facing conveyance surface passing through a capture region above the raw material layer and under the upper electrode, the conveyance surface including a nonconductor; separates charged conductive particles from the raw material layer surface by electrostatic force and adhering conductive particles to the conveyor belt conveyance surface; and separating and collecting the particles from the conveyance surface that moved outside the ele
