MAGNETIC SORTING APPARATUS MAGNETIC SORTING METHOD AND METHOD FOR MANUFACTURING IRON SOURCE

摘要

Provided are a magnetic sorting apparatus and a magnetic sorting method for efficiently separating ferromagnetic particles from a powder particle material containing the ferromagnetic particles and performing magnetic sorting at low cost without requiring complex steps wastewater treatment or the like. This magnetic sorting apparatus has: a conveyor belt for transporting a powder particle material containing ferromagnetic particles; a rotatable hollow belt guide roll wrapped in the conveyor belt around a portion of the outer periphery thereof; and a magnetic field application means positioned on the inner side of the belt guide roll the magnetic field application means having a plurality of magnets on the inner side of the belt guide roll and the ferromagnetic particles being separated in the magnetic field generated by the magnetic field application means. The magnets are arranged so that the magnetic poles adjoining in the peripheral direction of the belt guide roll have differing magnetism and so that the magnetic poles adjoining in the width direction of the belt guide roll have the same polarity.
