Zusammenfassung:	A device for electrostatically separating different kinds of crushed plastic pieces and correctly sorting them according to kind. The device comprises a classifying section (40) for classifying plastic pieces according to size, a frictional charging device (17), a pair of drum type electrostatic separating devices (41), and collecting sections (26) disposed below the electrostatic separating devices. Partition walls (52 - 55) for partitioning the collecting sections are constructed to be horizontally movable according to the fall positions associated with the polarity and amount of electric charge of each plastic piece (16). Therefore, separation can be correctly effected without changing the voltage from a high voltage power source device (24).
