Granulators are used in the process of manufacturing polymers; plastic/PET bottles et cetera. Granulators have been applied to raise the level of density of produced flakes. Granulators, depending on the installed extruder, are divided into three types:
  • Single screw;
  • Twin screw;
  • Tandem system;
The term ‘tandem system’ implies a presence of both single and twin screw systems being present. Using the cutting method, granulators can be classified into strand and non-strand granulators, the latter having the option of cold/hot cutting. Plastic granulators are used in the creation of polymer additives in filled compositions, to improve processing properties of powder formulations and the processing of PET bottles.
