The paper is devoted to the problems of research of induction machines for electrodynamic separation in the traveling magnetic field. Different designs of separators (with cylindrical or linear primary) are applied depending on capacity of units and on wastes properties. In these devices the force interaction is between the background magnetic field and eddy currents induced in conductive particles by a time changing magnetic field. The separating efficiency is greatly influenced by the magnetic pole reversal frequency and the effective flow density of magnetism. This leads to better separating results to suit the material. Separation of non-ferrous metal grain sizes from 150 mm down to 5 mm is possible - and in certain cases, down to a grain sizes of 1mm. Non-ferrous metal separators can be used as stand-alone solutions, and in combination with shredder and classifying systems, in a variety of recycling plants and at metallurgical enterprises for non-ferrous metals refinement.
