<p>An apparatus is provided for accurately sorting pulverized plastic chips of different kinds by electrostatic selection. The apparatus comprises a sorter (40) for sorting plastic chips according to size, a triboelectrification device (17), a pair of drum type electrostatic separators (41), and collectors (26) arranged under the electrostatic separators. The structure of partitions (52-55) that separates the collectors can be horizontally moved depending on where plastic chips (16) having different polarities and charges fall. There is no need for varying the voltage of a high-voltage supply (24) to separate chips accurately.</p> |
