摘要 |
<p>The invention relates to a method for the production of granulate grains of polymers from thermoplastic polyesters or copolyesters from a polyester melt using an extrusion granulator. The polyester melt is fed to nozzles of the extrusion granulator and then, with draw-in rollers, to the granulation device via an extraction section as extrusions exiting from the nozzle, wherein, e.g., an extrusion extraction speed is set by the draw-in rollers. The invention also relates to an improved extrusion granulator according to the invention having a wave device between the nozzles and the extraction channel, and granulate grains produced according to the method according to the invention.</p> |
