Abstract
A friction electrifying-type electrostatic sorting apparatus having a preliminary friction electrifying unit for preliminarily electrifying a sorted material by providing a friction; a friction electrifying unit for further electrifying the sorted material having been preliminarily electrified by the preliminary friction electrifying unit; a feeding unit for supplying the sorted material having been electrified by the friction electrifying unit; and an electrostatic sorting unit for electrostatically sorting the electrified material supplied from the feeding unit according to the electrified state of the sorted material by providing the sorted material in an electrostatic field.
Claims21
A friction electrifying-type electrostatic sorting apparatus, comprising:
- a preliminary friction electrifying unit for preliminarily electrifying a sorted material by providing a friction
- a friction electrifying unit for further electrifying the preliminary friction electrified sorted material, said friction electrifying unit having a chamber with a lining of an electrifying material provided on an inner wall of the chamber and a mechanism for moving the chamber to provide said further electrifying of the preliminary friction electrified sorted material by a corresponding movement of the chamber lining;
- a feeding unit for supplying the sorted material having been electrified by said friction electrifying unit;
- and
- an electrostatic sorting unit for electrostatically sorting the electrified sorted material supplied from said feeding unit according to the electrified state of the electrified sorted material by exposing the electrified sorted material to an electrostatic field.
A friction electrifying-type electrostatic sorting apparatus, comprising:
- a preliminary friction electrifying unit for preliminarily electrifying a sorted material by providing a friction;
- a friction electrifying unit for further electrifying the sorted material having been preliminarily electrified by said preliminary friction electrifying unit;
- a feeding unit for supplying the sorted material having been electrified by said friction electrifying unit;
- an electrostatic sorting unit for electrostatically sorting the electrified material supplied from said feeding unit according to the electrified state of the sorted material by providing the sorted material in an electrostatic field;
