Sepg. nonferrous metals from moving mixt. - involves alternating field of eccentric magnetised rotor within tube over which poorly conductive conveyor belt runs

摘要

The mixt. is deposited by vibration on an endless conveyor belt (3) running around driven and idling drums (7,6) and a cylindrical tube (1) forming a glide track (2). A magnetic rotor (17) is mounted eccentrically (22) within the tube (1) on which a series of rollers (26,26") is carried in one quadrant (13) at right angles to the direction of travel (5). The alternating magnetic field produced by the eccentric rotor (17) permeates the material of the belt (3) which is a poor electric conductor. USE/ADVANTAGE - Frictional contact and prodn. of heat between the belt and the glide track are reduced. Sepg. of monferrous metals from moving mixt.
