Beschreibung
Zusammenfassung:	A continuous granulator comprises a longitudinal granulation chamber having a first end with an inlet for powder material and a binder feed port and a second end with an outlet for granulated product. The granulation chamber comprises at least two parallel rotary shafts provided with granulating elements and forming an angle of from 0 to 70 degrees with the vertical. Each granulating element on a shaft comprises at least one lobe having limited extent in the circumferential direction of the shaft and interleaving with a lobe of a granulating element on another shaft. A plurality of such separate granulating elements are distributed from the inlet to the outlet, and successive granulating elements on a shaft are mutually angled.
