Abstract

Si propone un procedimento per il trattamento di rigenerazione selettiva di terre usate da fonderia, in cui avviene una separazione di percentuali dei leganti dalla massa di base granulare mediante mezzi meccanici e successivamente i granelli o granuli di terra vengono accelerati in modo da generare un'azione di sfregamento dei singoli granelli di terra tra loro. Dopo di che viene effettuata una separazione tra granuli grossi e piccoli e poi eventualmente un post-trattamento.
