子の分離装置。 A device for separating non-magnetic particles from a mixture of magnetic particles and non-magnetic particles, which comprises: an insulator provided on the outer periphery of a rotationally driven magnetic roll; a conductor provided on the circumferential surface; a wire embedded in the conductor and extending in the axial direction of the magnetic roll, and configured such that the mixture adsorbed on the conductor moves on the conductor by rotational driving of the magnetic roll,
An alternating current voltage is applied between the conductor and the wire so that an electric field that exerts a repulsive force on the non-magnetic particles is formed outside the conductor, and the wire is applied to the insulator and the conductor. 1. A device for separating non-magnetic particles, characterized in that it is provided with a communication part that communicates with the outside of a conductor.
