The ASPTM series shredding and pelletizing system is a comprehensive solution that integrates shredding, crushing, feeding, plasticization, and pelletizing into one efficient process.
This system is specifically designed for the recycling and pelletizing of various types of plastics, including film, raffia, trim, purge, hollow parts, bottles, and foaming materials. It offers an integrated and cost-effective approach to processing all kinds of plastic waste, making it ideal for both industrial and plant-based recycling operations.
Shredding & Feeding
In collaboration with European shredder suppliers, the system uses specialized shredding rotors that work in conjunction with single-screw extruders. This ensures efficient pre-reduction, crushing, and feeding of different types of plastic scraps, such as films, bottles, woven or non-woven bags, fabrics, purges, and lumps. The system is versatile and can handle all kinds of plastic waste regardless of their condition.
Melt Filtration
A standard single-plate or piston double-station screen changer, or a non-stop double-plate or piston four-station screen changer, can be installed on the extruder head. This ensures effective filtration of the melted plastic. The level of filtration required depends on the quality of the input material and the intended use of the final granules.
Plasticization & Degassing
A specialized single-screw extruder is used to gently melt the crushed plastic scraps. The material is processed through a 32D section to ensure proper melting and plasticization. A dual-zone vacuum degassing system helps remove volatile substances like moisture and low-molecular compounds, making this system especially suitable for heavy printed or moisture-sensitive plastic scraps.
Pelletizing
The die-face water ring pelletizing system is the standard method used in the ASPTM system. The system features a self-adjusting pelletizing head that ensures optimal granulate quality and long service life by maintaining consistent blade pressure. The rotational speed of the blades automatically adjusts based on the extrusion pressure of the melt.
