Abstract:
The invention relates to a method for making granules from strands of a melt of a thermoplastic polymer material having the steps of creating and providing the melt of the material, discharging the material in multiple strands from a perforated plate, impinging the strands with an impinging flow fluid from an impinging flow nozzle, cooling the strands and dividing the strands into individual granules, wherein the strands are impinged by the impinging flow fluid only during discharge from the perforated plate, and wherein, as it is discharged from the impinging flow nozzle, the impinging flow fluid has a temperature above the melting temperature of the material and has a discharge velocity in the range from 50 m/sec to 300 m/sec; the invention also relates to a device for carrying out the method with an impinging flow device that can be pivoted by means of a pivoting joint.
