Abstract

This paper deals with a recycling and reusing of non-conformity product during the production of magnets. Theoretical part of the paper contains general facts about permanent magnets and theirs productions. Experimental part describes methodology of non-conformity product processing by dry milling to ensure optimal conditions for rebuilding the material to reuse it in production cycle. Granulometry analysis of the milled material showed the formation of clumps and aggregates of size from 20 to 30 microns but an ideal particle size suitable for the production of the magnets is about 1 micron. After evaluation and mutual comparison of results, appropriate measures have been proposed in the recycling technology which has been used.

Keywords: recycling, magnets production, non-conforming products, milling
