To provide an electric discharge type static separator of improved recovery ratio of insulating crushed refuse.
An electric discharge type static separator is provided with a grounding first metal drum electrode 15 on which crushed refuse 11 to separated is scattered on its upper face, a discharge metal-shaped high voltage electrode 16, a first brush 17 for scraping crushed refuse 11 adsorbed and separated onto the metal drum electrode 15, a grounding second metal drum electrode 18 constituted of a plurality of metal disks disposed below the first metal drum electrode 15, a second brush 19 for scraping the crushed refuse 1 to be separated being adsorbed on the grounding second metal drum electrode 18, a first separation container 21 disposed below the second metal drum electrode 18 and on its front position, and a second separation container 22 disposed below the grounding second metal drum electrode 18 and on the rear position. Insulating crushed refuse 11B is separated from conductive crushed refuse 11A and recovered by the above constitution, and areas on which the insulating crushed refuse 11B adheres are increased by a plurality of metal disks to improve the recovery ratio of the insulating crushed refuse 11B.
