Abstract

Fließbett-Gegenstrahlmühlen sind Gasstrahlmühlen, mit denen sich sehr hohe Mahlfeinheiten bei äußerst gerin­ gem Verschleiß erreichen lassen. Eine Verbesserung des Mahlergebnisses läßt sich durch Abkühlung der Gasstrah­ len mittels eines Kältemittels erreichen, jedoch ist die erreichbare Verbesserung nicht erheblich und der Kältemittelverbrauch sehr hoch. Zwecks Senkung des Kältemittelverbrauchs bei gleichzeitiger beträchtlicher Verbesserung der Mahlfeinheit wird das vom Sichter (5) der Mühle abgetrennte Grobgut (11) durch das Kältemittel innerhalb der Fließbett-Gegenstrahlmühle gekühlt und in die Mahlkammer (2) zurückgeführt. Als Kältemittel wird flüssiger Stickstoff bevorzugt, mit dem der Sumpf (3) der Mühle gekühlt wird.
