Plastic granulation process is the key, most technologically advanced phase of the plastics recycling process, in which the recycled materials in the form of regranulates are obtained from the used plastic waste.

Reached as the final granulation product and being the case of many different products, regranulates to be able to reused, they must be properly cleaned of all pollutants and meet all required quality standards.

The granulating lines for plastics industry are the set of automated devices enabling the processing of shredded and grinded input materials of a wide range of plastics such as: PP, PE, HDPE, LDPE, LLDPE, ABS, EPS into a final regranulate products in the form of fine pellets. The advancement of processing on granulating lines consists in subjecting the processed material to appropriate physical processes such as compaction, compression at high temperatures, cooling, drying and pelletizing. The granulating lines design varies depending on the type of material processed, the degree of its contamination and the obtained regranulate quality to achieve required quality standards.

Typical granulating line consists of:

belt conveyor – provides input material;
compactor (agglomerator) or hopper (depending on the recycled material) – the first condenses and heats the material, the second is only the entry of material into the plasticizing system;
extruder – homogenises the material and eliminates air bubbles on the product by removing gas formed during extrusion;
hydraulic screen changer – cleans the material from contaminations using a filter mesh;
pelletizer (water ring pelletizing system) – cuts the material into suitable granules;
vibrating screen – dries, separates pellets from water;
granules centrifuge – centrifuges granulate from water;
collection and packaging system (transport hopper and packaging station) – transports the product for packaging;
control system – manages the operation of the extruder in individual plasticizing zones.
