COMPOUNDING, PELLETIZING AND RECYCLING
The common compounding process follows the mixing operations below:

PREMIXING OF INGREDIENTS

Additives - Alloys - Antioxidants - Blends - Colour Pigments
Compatibilizers - Composites ingredients

This is made either by batches in an AXON High Speed Propeller Mixer or in an AXON continuously operated Intensive Mixer or both methods in named order.

COMPOUNDING

Fillers - Fibres - Fire retardants - Lubricants
Masterbatches - Plasticisers - Other additives

When the batch or batches of incorporated ingredients are premixed they will be delivered to the extruder for compounding to pellets as follows:
There are two methods of compounding, namely the String-Pelletising and the Die Face Cutting. The later method is used when very high content of unmeltable fillers shall be used and the polymer allows this technique.

TURN KEY EXTRUSION FACTORIES

- For Masterbatch Colour Concentrate and other additives.
- For Film Blowing and bag making directly from the Extruder.
- For Pipes, Tubes and Profiles.
- For Sheet Extrusion.

RECYCLING

Most of today's rejects are reclaimed just by shopping them in a granulator.

The IN-HOUSE RECYCLING is essential

Filtering during re-processing through an automatic screen-changer:
The most important difference between recovery by cold grinding and recycling through melting and plasticising of the regrinds is the thermal reprocessing and the better homogenisation through plasticising of the regrinds, but also the filtering of the melt by an automatic screen changer. All dirt will stay in the filter and first class pellets will be produced for reuse. It is this recycling that makes the rejects to new first class pellets.

Film recycling directly from the film spool: In our newsletter No. 30 an example of film scrap recycling directly from the film spool is illustrated. In this case the reclaimed material is fed as film directly into the extruder and goes as strings to the pelletiser.

The recycling of film scrap from edge-trims on reels is usually made parallel with other recycling work.
