Title:
APPARATUS FOR SEPARATING PLASTIC CHIPS
Document Type and Number:
WIPO Patent Application WO/2002/020164
Kind Code:
A1
Abstract:
A first electrostatic separator and a second electrostatic separator are vertically arranged in lower part of a triboelectrification device. The electrostatic separators each include a drum electrode and an opposing electrode between which an electrostatic field for separation is formed. Plastic chips separated by the electrostatic field in the first electrostatic separator are delivered to the electrostatic field in the second electrostatic separator for further separation so that plastic chips can be separated more precisely and efficiently.
