Abstract

Die Erfindung betrifft einen Rostkühler, der senkrecht zum Drehrohrofen angeordnet ist, wobei die vertikale Längs­ mittelebene des Kühlers von der Stirnseite des Drehrofens einen Abstand zwischen 10 und 150 cm aufweist und in der unterhalb des Drehrofen-Gutaustrags-bereiches liegenden Zone des Rostkühlers pro Flächeneinheit mehr feststehende und mehr unbelüftete Rostplatten als in den seitlich angren­ zenden Zonen des Gutaufgabeendes und im übrigen Bereich des Kühlers vorhanden sind. Dadurch wird ein guter Schutz der Rostplatten des Gutaufgabeendes sowie eine gleichmäßige Verteilung des Gutes über die ganze Kühler­ breite mittels eines in Bewegung befindlichen Schüttkegels erreicht. The invention relates to a grate cooler that is vertical is arranged to the rotary kiln, the vertical longitudinal center plane of the cooler from the front of the rotary kiln has a distance between 10 and 150 cm and in the below the rotary kiln discharge area Zone of the grate cooler more fixed per unit area and more unventilated grate plates than in the side zenden zones of the Gutaufgabeende and in the remaining area of the cooler are present. This will provide good protection the grate plates of the end of the supply and one even distribution of the goods over the entire cooler width by means of a moving cone reached.
