Issues of induction sorting of scrap and waste of non-ferrous metals

Abstract

Nowadays, one of the main economic advantages is using secondary raw materials for the production of useful materials for further use. The greatest environmental and economic effect provides the use of secondary non-ferrous metals. Eddy-current separation based on interaction force of a magnetic field with eddy currents induced by this field in conducting particles, is the most effective for the recycling of non-ferrous metals. The paper is devoted to the problem of non-ferrous metals sorting. The research results of the number of traveling magnetic field separators designs are described. The ways of improving separation efficiency are shown. Eddy-current 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.
