The ASPTM series shredding and pelletizing system is a fully integrated solution that combines shredding, crushing, feeding, plasticization, and pelletizing in one seamless process. Designed for the plastics recycling industry, this system offers an efficient and cost-effective way to process various types of plastic waste, including film, raffia, trim, hollow parts, bottles, and foam materials.
**Shredding & Feeding**
In collaboration with European shredder suppliers, the ASPTM system uses specialized shredding rotors that work in conjunction with single-screw extruders. This combination allows for pre-reduction, crushing, and efficient feeding of different types of plastic scraps, such as films, bottles, woven bags, fabrics, purges, and lumps. The system is designed to handle all kinds of plastic waste in any condition, making it highly versatile.
**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. These filtration units ensure high-quality output by effectively removing impurities from the molten plastic. The choice of filtration technology depends on the quality of the input material and the intended use of the final pellets.
**Plasticization & Degassing**
A specialized single-screw extruder is used to gently melt and plasticize the crushed plastic scraps. The system includes a 32D processing section, ensuring thorough melting and homogenization. A dual-zone vacuum degassing system efficiently removes moisture and low-molecular-weight compounds, making it ideal for processing heavy-printed and moisture-sensitive materials.
**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 maintains consistent blade pressure for optimal pellet quality and long service life. The rotational speed of the blades is automatically controlled based on the extrusion pressure, ensuring stable performance throughout the process.
