   Ist also entweder der Schlackenzufluss so stark oder die Temperatur der Schlacke so hoch. dass sich das Gemenge nicht schon während des Zerstäubungsvorganges an der Luft genügend abkühlt, so muss für künstliche Abkühlung gesorgt werden. Eine solche künstliche Abkühlung erreicht man   zweckmässig   durch Zufuhr von Flüssigkeiten in geeigneten Mengen unmittelbar nach dem Schleudern. Dies kann man beispielsweise vorteilhaft dadurch bewirken, dass man die letzte Trommel unter der darüber angeordneten etwas vorstehen und auf diese die Kühlflüssigkeit in Gestalt eines feinen Regens, z. B. durch eine Brause d (siehe Zeichnung) auffallen lässt. Die Kühiflüssigkeit wird auf diese Weise fein verteilt in das Gemenge hineingebracht, wodurch die Abkühlung nicht nur beschleunigt, sondern auch gleichmässiger bewirkt wird. 



   Werden zu diesem Zwecke   Kühlflüssigkeiten   gewählt, die Zuschläge gelöst enthalten, wie z. B. Kalkwasser, Kalklauge oder sonstige alkalische Lösungen, so wird das Gemenge noch mit 
 EMI2.1 
 dadurch das Treiben des Zementes verhütet.

   So is either the slag inflow so strong or the temperature of the slag so high. Artificial cooling must be provided to ensure that the mixture does not cool sufficiently in the air during the atomization process. Artificial cooling of this kind is expediently achieved by adding liquids in suitable quantities immediately after spinning. This can be achieved, for example, advantageously by the fact that the last drum protrudes slightly below the one above and the cooling liquid is applied to it in the form of a fine rain, e.g. B. by a shower d (see drawing) can be noticed. In this way, the cooling liquid is finely dispersed and brought into the mixture, which not only accelerates the cooling but also makes it more even.



   If cooling liquids are selected for this purpose that contain dissolved additives, such as. B. lime water, lime lye or other alkaline solutions, the mixture is still with
 EMI2.1
 thereby preventing the cement from floating.
