Electrostatic separators recover metals from e-scrap
Eriez now offers advanced, cost-effective electrostatic separators that utilize surface conductivity to recover valuable metals from electronic scrap, including chopped wire. Electrostatic separation relies on the difference in surface conductivity of the materials to be separated. Fine conductive and non-conductive particles can be efficiently separated using Eriez Electrostatic Rotor Separators. Applications for this technology include: chopped wire (Cu and Al); computer scrap; circuit boards; complex scrap; aluminum and PE Dealer-mix cable and ACSR cable.
With Eriez Electrostatic Rotor Separators, a high-potential electric charge is applied to the material via an energized pinning electrode. The conductive particles dissipate this charge and are subsequently thrown from the rotor by centrifugal force. Non-conductive particles are not able to dissipate the charge and are pinned to the grounded roll surface. The non-conductive particles are subsequently removed from the rotor surface mechanically by a brush and aided by an AC wiper used to negate the charge.
