Method of melting magnetically weak particles of arbitrary shape into substantially spherically-shaped globules

摘要

A method of reshaping magnetically relatively weak ferrite particles of substantially arbitrary shape into substantially spherically-shaped globules including the steps of transporting the particles by a carrier gas stream within a conduit into the vicinity of a stream of warm gases, separating the particles from the carrier gas stream prior to contact with said warm gas stream, feeding the separated particles into the stream of warm gases, melting the particles therein, and subsequently allowing the particles to solidify into substantially spherically-shaped globules.
