Abstract

L'invenzione ha per oggetto un separatore dinamico per materiali polverulenti, in particolare cementi, del tipo a cestello rotante spazzato da un flusso di aria quale mezzo di separazione, caratterizzato dal fatto di comprendere una coppia di cestelli rotanti separatamente disposti in serie l'uno sovrastante l'altro, ciascuno di detti cestelli venendo spazzato da un flusso di aria alimentato indipendentemente all'interno del separatore verso ciascun cestello attraverso un condotto a spira con ingresso ed uscita tangenziali, così che ciascun flusso di aria spazzando ciascun cestello provoca la formazione di due tagli granulometrici di separazione, un fine che esce da detti condotti tangenziali ed un grossolano che scende all'interno del separatore, il separatore producendo in tale modo tre tagli granulometrici complessivi.The invention relates to a dynamic separator for powdery materials, in particular cements, of the rotating basket type swept by a flow of air as a separation medium, characterized in that it comprises a pair of rotating baskets separately arranged in series each above the other, each of said baskets being swept by a flow of air fed independently inside the separator towards each basket through a spiral duct with tangential inlet and outlet, so that each flow of air by sweeping each basket causes the formation of two separating granulometric cuts, one end coming out of said tangential ducts and one coarse that descends inside the separator, the separator thus producing three overall granulometric cuts.
