Abstract
Viene proposto un procedimento per il trattamento di rigenerazione a cariche di terra usata da fonderia prevalentemente legata ad argilla per il suo reimpiego. Le particelle polverulente, le quali si staccano a seguito dell'azione di sfregamento dai granuli di terra, vengono aspirate per via pneumatica durante il trattamento. In questa maniera risulta una riduzione di peso della carica, la quale viene compensata per quanto riguarda il peso o rispettivamente il volume con aggiunta di una determinata quantità di terra.Con questo procedimento deve essere raggiunto che l'azione di sfregamento e quindi il distacco degli involucri dei granuli di terra vengono mantenuti costanti durante l'intero trattamento a cariche.
