As an example of a practical separator, recent prominent recycling technology of copper and resin from printed wiring boards in the electronic circuits was introduced.
Mixed plastic electrostatic separator. Working principle of electrostatic separator. Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material. Generally, electrostatic charges are used to attract or repel differently charged material. When electrostatic separation uses the force.
Sep 10, 2012 . In this work, we made a novel attempt to recover the mixtures containing conductors (copper), semiconductors (extrinsic silicon), and nonconductors (woven glass reinforced resin) by electrostatic separation. The results of binary mixtures separation show that the separation of conductor and nonconductor,.
(a) Bare copper particles and (b) tinned copper particles from grinded electric cable wastes. Experiments have been made on a roll-type electrostatic separator (CARPCO, Inc) with new electrode configurations (Fig. 2). In these separators, a vibratory electromagnet- ic feeder (1) brings the particulate mixture onto the surface.
