Title:
ELECTROSTATIC SORTING APPARATUS AND METHOD OF ELECTROSTATIC SORTING
Document Type and Number:
WIPO Patent Application WO/2008/075470
Kind Code:
A1
Abstract:
An electrostatic sorting apparatus characterized by including earth electrode (1) disposed on one side of the falling path of sorting object; high-voltage application electrode (2) disposed on the other side of the falling path so as to be opposite to the earth electrode (1); first air current generating means for generating an air current in a direction imparting a drag to gravity to either an electrostatic field occurring between the earth electrode (1) and the high-voltage application electrode (2) or separation space (77) provided inferior to the earth electrode (1) and the high-voltage application electrode (2), or both thereof; and second air current generating means for generating an air current against the electrostatic field occurring between the earth electrode (1) and the high-voltage application electrode (2) in parallel to the electrostatic field.
