Abstract
A first and second electrostatic sorting sections are arranged below a tribo-electrifying device in this order in a vertical direction to form a sorting electrostatic field between a drum electrode and an opposing electrode. Plastic pieces separated from the other plastic pieces by the sorting electrostatic field in the first electrostatic separating section are introduced into a sorting electrostatic field in the second electrostatic separating section for second separation, thereby increasing the separation purity and recovery rate of plastic pieces.
