The improvement of technologies for the collection and primary processing of secondary nonferrous metals is a prerequisite for the development of secondary non-ferrous metallurgy and the establishment of solid waste processing enterprises. One such technology is eddy-current (electrodynamic) separation in a traveling magnetic field. The main structures of electrodynamic separation installations are considered. Widely distributed separators based on linear inductors. Such separators easily fit into technological lines and are used in the extraction of non-ferrous metals from various types of metal-containing solid waste (automobile scrap, mixed production and municipal waste, cable and electronic scrap, etc.), as well as in the processing of complex non-ferrous scrap in preparation it to metallurgical redistribution. Еlectrodynamic separation problems can be conditionally divided into two groups. The first group includes the tasks of separating non-ferrous metals from non-metals, and the second group involves more complex tasks of sorting metals according to their physical properties. In both cases, the final results of separation depend on the combined action of electromagnetic and mechanical forces on metallic particles. This article describes some of the results of studies of electrodynamic separators based on linear inductors. The prospects for the use of linear inductors that create opposite direction traveling magnetic fields are shown. The use of such linear inductors in electrodynamic separators to remove non-ferrous metals from solid waste allows for an increase in the yield of metals. The use of opposite direction traveling magnetic fields in the induction sorting of metals and alloys provides increased plant productivity and improved sorting quality. It is shown that the distribution of the magnetic field and electromagnetic forces along the inductors depend on the three-phase winding circuit. The main attention is focused on the choice of the three-phase winding of the linear inductor, which provides these advantages. The article presents the results of experimental studies of prototypes of electrodynamic separators based on linear inductors, created in the laboratory of the Department of Electrical Engineering and Electrotechnological Systems of the Ural Federal University. The article presents the results of studies of of dual-purpose linear induction machines created in the laboratory of the Academic Department of Electrical Engineering and Electrotechnological Systems of the
