The ASPTM series shredding and pelletizing system is a complete solution that integrates shredding, crushing, feeding, plasticization, and pelletizing into one efficient process. Designed for the plastics recycling industry, this system offers an integrated and cost-effective approach to processing various types of plastic waste, including film, raffia, trim, purge, hollow parts, bottles, and foaming materials.
**Shredding and Feeding**
In collaboration with European shredder suppliers, the ASPTM system uses specialized shredding rotors that work in conjunction with single-screw extruders. This setup ensures effective pre-reduction, crushing, and feeding of various types of plastic scraps, such as films, bottles, raffia, woven bags, fabrics, purges, and lumps. The system is designed to handle all kinds of plastic waste regardless of its condition or form.
**Melt Filtration**
The system can be equipped with either a standard single-plate/piston double-station screen changer or a non-stop double-plate/piston four-station screen changer at the extruder head. This advanced filtration technology ensures high-quality output by removing impurities and contaminants, depending on the quality of the input material and the intended use of the final granules.
**Plasticization and Degassing**
A specialized single-screw extruder is used to gently melt and plasticize the crushed plastic scraps. The system includes a 32D processing section, along with a dual-zone vacuum degassing system, which efficiently removes moisture and low-molecular compounds. This makes it particularly suitable for processing heavily printed or moisture-sensitive plastic waste.
**Pelletizing**
The die-face water ring pelletizing system is the standard granulating method in the ASPTM system. It features a self-adjusting pelletizing head that ensures optimal granulate quality and long service life through consistent blade pressure. The rotational speed of the blades is automatically adjusted based on the extrusion pressure, ensuring smooth and stable operation.
