ABSTRACT:
A system for the continuous dielectrophoretic separation of mixtures of particulate and granular materials by passing the materials through a divergent electric field created in a fluid dielectric medium by applying a voltage to an electrode configuration including a rotatable cylindrical-shaped electrode having a non-uniform conductor surface and a stationary perforate electrode spaced therefrom to define a contact zone. The particles having dielectric constants lower than that of the fluid medium are collected through the perforate electrode while those particles having dielectric constants higher than that of the fluid medium are attached to and separated by the rotatable electrode.
