Abstract

1324126 Separation by induced electromotive forces VANDERBILT UNIVERSITY 15 June 1971 [15 June 1970] 27926/71 Heading B2J Particles having different electrical conductivities are classified by subjecting them to a magnetic field moving in an endless path whereby electromotive forces are induced in said particles corresponding to their conductivities, the magnetic field and its velocity being large enough to cause movement of the particles in the direction of said moving field. As shown, a plurality of electromagnets 25, 30 are rotatably mounted on carriers 23, 28 to rotate in circular paths above and below a fixed platform 13. The electromagnets are uniformly spaced on the carriers with respective upper and lower magnets in alignment. The carriers are synchronously driven by belts 32, 34 from a drive shaft 33. When particles to be classified are dropped into chutes 38, those which are non-conducting pass radially across platform 13 whereas those which are conducting are diverted to a degree depending on their conductivity (Fig. 2, not shown). Mutual separation of particles of copper, tin and glass is referred to. The electromagnets may be replaced by permanent magnets.
