ABSTRACT:
The centrifugal pelletizer proposed in the present invention is applicable for producing pellets from a molten metal, such as magnesium or aluminium. The pelletizer comprises a hollow drive shaft, which is enclosed in a housing and rotates in bearings, and a hollow transmission shaft accommodated in the hollow drive shaft so as to define an annular gap between it and said drive shaft. The bottom end of the transmission shaft is rigidly coupled to the drive shaft. In addition, the transmission shaft features a frictional coupling with the drive shaft provided in the bottom portion thereof. In such a centrifugal pelletizer any contact of the molten metal with the drive shaft is fully obviated, which provides for favorable conditions for operation of both said shaft and the bearings in which it rotates.
