Used in combination, and alongside magnetic separators, the Eddy Current Separator and ElectroStatic Separator enable the recovery of a high proportion of the metallic (ferrous and non-ferrous) materials from any waste. In practice, the Eddy Current Separator is ideally suited for recovering or separating non-ferrous metals above 3mm.

Electrostatic separation is an effective and environmentally friendly method for recycling comminuted waste printed circuit boards (PCB). As a classical separator, the roll-type corona-electrostatic separator (RTS) has some advantages in this field. However, there are still some notable problems, such as the middling products and their further …

Abstract. The scientific understanding of the nature of magnetic force appears to have started early in this century with the work of Langevin, in France. He explained diamagnetism and paramagnetism in terms of orbiting electrons. Another French physicist, Pierre Weiss, followed closely with a qualitative hypothesis for ferro-magnetic behaviour.

We introduce a new approach for the separation of the electrostatic and magnetic components of the electron wave phase shift, based on the transport-of-intensity equation (TIE) formalism. We derive two separate TIE-like equations, one for each of the phase shift components. We use experimental results on FeCoB and Permalloy …
