Abstract

Bei der Herstellung von einbasigen Treibladungspulvern mit Alkohol und Ether als Lösungsmittel besteht die Gefahr, daß Etherblasen im Treibladungs-Pulvermaterial entstehen, welche die Qualität des Treibladungspulvers erheblich vermindern. Erfindungsgemäß ist vorgesehen, daß das Treibladungs-Pulvermaterial vor dem Austritt aus der Extrudervorrichtung gekühlt wird. Dazu ist der Extruderkopf (4) mit einer Kühleinrichtung versehen. Die Erfindung ist insbesondere zur Herstellung von einbasigen Treibladungspulvern mit Alkohol und Ether als Lösungsmittel verwendbar.
