Abstract

Un procedimento per la separazione di acciaio inox da materiali misti che lo contengono, in cui questi materiali vengono convogliati attraverso un campo magnetico con un gradiente di potenziale magnetico superiore a 1.500 Oe/cm con conseguente attrazione ed arresto dell'acciaio inox e sua separazione dagli inerti che non vengono attratti. Tale procedimento viene realizzato con un dispositivo comprendente un generatore di campo magnetico costituito da una molteplicità di magneti disposti in file e righe parallele nelle quali le polarità dei magneti risultano alternate sia in ciascuna fila che in ciascuna riga, tutti i magneti essendo magneticamente isolati fra loro.A process for the separation of stainless steel from mixed materials that contain it, in which these materials are conveyed through a magnetic field with a magnetic potential gradient greater than 1,500 Oe / cm with consequent attraction and arrest of the stainless steel and its separation from the aggregates that are not attracted. This process is carried out with a device comprising a magnetic field generator consisting of a multiplicity of magnets arranged in parallel rows and rows in which the polarities of the magnets are alternated both in each row and in each row, all the magnets being magnetically isolated from each other .
