Exemplary structure of a granulation process

  • Melt pump
  • Melt filter
  • Purge valve
  • Pelletizer

  • Melt pump

    The melt pump conveys the polymer melt flow from the extruder to the downstream equipment. In this setup, a melt filter is located downstream of the pump to remove impurities from the polymer melt.

  • Melt filter

    The melt filters are installed downstream of the gear pump to clean up the polymer melt. They filters extract solids and contaminants from the melt flow. The filters are particularly suitable for extrusion processes in which PET or PA is processed.

  • Purge valve

    The purge valve is used to regulate or separate the melt flow. Purge valves divert the product flow and thus prevent degenerated start-up material from entering the production cycle in the event of a shutdown or a product change.

  • Pelletizer

    As the name suggests, the pelletizer produces plastic pellets from which a wide variety of products can be manufactured in subsequent processing stages. Pellets can be produced in different shapes depending on the use of a corresponding pelletizer. A distinction is made between cylindrical or round granules and microgranules for example,.
