Alternating Field Magnetic Separator.
U S Pat 3 988 240 1976 Oct; :
A magnetic matrix separator for selectively separating diverse particles subjects the particles to the interaction of vibratory and magnetic forces induced cojointly by the application of an intensified intermittent or alternating magnetic flux to the matrix. Continuous, dual separating actions are obtained with a flexibly mounted circular matrix structure caused to rotate with respect to the pole faces of a pair of u-shaped electromagnets. Use of a systematic arrangement of uniformly shaped matrix components facilitates rapid processing of the particles for separation.
