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.

Electrostatic separator

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 electric field.

Electrostatic separator and electrostatic separation method

Vacuum chamber made of aluminum or its alloys, and surface treatment and

Zn-Mg alloy is plated by vapor deposition on the surface of metals. Since Zn and Mg are vapor-deposited as a vapor mixture of an optional ratio on the surface of metals, plated layers of excellent corrosion resistance, peeling resistance of coating film, formability, etc. can be formed. There is disclosed a method of forming uniform vapor mixtures of Zn and Mg, and vapor-depositing them on the surface of metals as the method forming the vapor-deposited layers.

Zn-Mg alloy vapor deposition plated metals of high corrosion resistance,

Provided herein is an Al-Cr alloy vapor deposited product having high corrosion resistance which can be used under a corrosive environment for a long period of time on account of the outstanding corrosion resistance and heat resistance of the Al-Cr alloy vapor deposited layer.
