What is Plastic Granulating Line?

Plastic Granulating Lines play a crucial role in the recycling process, particularly for various types of waste plastics such as Polyethylene (LLDPE, LDPE, HDPE), Polypropylene (PP), Polystyrene (PS), and Acrylonitrile Butadiene Styrene (ABS). These lines are designed to efficiently process plastics in film, rigid, or foam form, transforming them into usable granules for further manufacturing.

The selection of machines and features within Plastic Granulating Lines is tailored to factors such as hourly throughput, the form and shape of the waste, as well as its humidity levels. This customization ensures optimal performance and efficiency in the recycling process, allowing for effective handling of diverse types of plastic waste.

Size reduction is often a necessary step before the extrusion process, depending on the form and size of the input material. Size reduction equipment, such as shredders or granulators, is carefully chosen to suit the specific characteristics of the input material. This step helps to prepare the waste plastic for extrusion, facilitating smoother processing and higher-quality output.

In some cases, size reduction and extrusion processes are combined in a single step using advanced equipment like the CRT Extruder Shredder. Alternatively, size reduction can be carried out separately by a shredder or granulator before proceeding to the granule extruder. This flexibility allows for adaptability to different processing needs and ensures efficient utilization of resources.

During the extrusion process, plastics are densified and transformed into pellets through fully automated and PLC controlled CRT Extruder Densifiers. These advanced machines streamline the production process, ensuring consistency and precision in pellet formation. The resulting pellets are then filtered and cut automatically by pelletizers, further enhancing efficiency and quality control.

Finally, the pellets are pneumatically transferred to storage silos or big bag filling stations based on the required throughput. This automated handling process minimizes manual intervention and reduces the risk of contamination, ensuring the integrity of the final product. By incorporating advanced technology and automation, Plastic Granulating Lines optimize the recycling process, promoting sustainability and environmental responsibility in the plastics industry.
