Abstract

A centrifugation station for extrusion plants comprises a tubular body, a shaft and an impeller. The tubular body internally defines a processing duct extending along a central axis between a supply section and a release section. The shaft has an upper portion extending in the supply section and a threaded lower portion extending in the release section. The impeller is fitted around the upper portion of the shaft and is rotatable around the central axis independently of the shaft. Furthermore, the impeller is provided with a plurality of blades angularly spaced from each other and shaped to distribute the molten material to be extruded on an inner wall of the supply duct favouring the extraction of any volatile compounds from the material to be extruded.

Dependent claims

A centrifugation station for extrusion plants comprising:

a tubular body internally defining a processing duct extending along a central axis between a supply section defining an inlet of a material to be extruded in molten form and a concurrent release section defining an outlet nozzle of said material to be extruded;
a shaft having an upper portion extending in said supply section and a threaded lower portion defining an endless screw extending in said release section and configured to promote the exit of the material from the outlet nozzle;
an impeller fitted around the upper portion of the shaft and rotatable around said central axis independently of the shaft, said impeller being provided with a plurality of blades angularly spaced from each other and shaped to distribute the molten material to be extruded on an inner wall of the supply duct favouring the extraction of any volatile compounds from the material to be extruded.
