PATENTAMT.PATENT OFFICE.
Der Apparat besteht aus einer die zu hydratisirenden Erdalkalien in Stücken aufnehmenden, langsam rotirenden Siebtrommel, welche entweder mit einer durchgehenden, hohlen Welle versehen ist oder in hohlen Zapfen lagert.The apparatus consists of an alkaline earth to be hydrated in pieces, slowly rotating sieve drum, which either has a continuous, hollow shaft is provided or stored in hollow pegs.
Das zur Erzeugung pulverförmigen Hydrates erforderliche Wasser wird in feinst vertheiltem Zustand — zerstäubt oder als Wasserdampf — durch die Mitten der Stirnwände eingeführt und entweder durch die mit vielen Oeffnungen versehene Welle oder frei durch die hohlen Zapfen in den Innenraum der Trommel einströmen gelassen.The water required for the production of powdery hydrates is very finely divided State - atomized or as water vapor - introduced through the centers of the end walls and either through the shaft with many openings or freely through the hollow pins allowed to flow into the interior of the drum.
Das zu Pulver gelöschte Gut wird, um einer ' zu weit gehenden Hydratisirung entzogen zu werden, sofort von der noch unzersetzten Masse durch Absieben getrennt, so dafs das einströmende Wasser immer neue Angriffsflächen des zu löschenden Materials findet. Unzersetzbare Beimengungen bleiben in der Trommel zurück und werden von Zeit zu Zeit ausge^ räumt.The good, extinguished to powder, is withdrawn from being too hydrated are immediately separated from the still undecomposed mass by sieving, so that the inflowing Water always finds new surfaces to attack the material to be extinguished. Indecomposable Additions remain in the drum and are discharged from time to time clears.
