To provide an inexpensive electrostatic sorting apparatus operated by voltage lower than that of a falling type or discharge type one and not too affected by a crushing size and enhanced in sorting capacity.
By providing a charge device 22 charging ground waste refuse 21 to be sorted, a disc metal plate electrode 24A receiving the application of high voltage and feeding the ground waste refuse 22 to be sorted delivered from the charge device 22 while horizontally rotated, a metal plate electrode 24B attracting the ground waste refuse 21 to be sorted repulsed by the metal plate electrode 24A, a first suction passage 28 recovering the ground waste refuse 21 to be sorted flown from the metal plate electrode 24A by centrifugal force, a second suction passage 29 recovering the ground waste refuse 21 to be sorted attracted on the metal plate electrode 24A and a third suction passage 31 recovering the ground waste refuse 21 to be sorted attracted to the metal plate electrode 24B, the ground waste refuse 21 to be sorted can be sorted and, since this waste refuse 21 is brought into contact with the metal plate electrode 24A to flow, it can be sorted by voltage lower than that of a conventional system.
