PS Granulator
For industries requiring high-quality, food-grade or medical-grade recycled PS materials—such as packaging, medical devices, and food containers—precision and purity are non-negotiable. The PSG-800 High-Precision PS Granulator is engineered to meet these strict standards, producing pellets with uniform size, low impurity content, and consistent quality. This advanced PS recycling machine integrates precision crushing, high-temperature melting, and precise pelletizing technologies, ensuring recycled PS meets FDA and EU food-contact regulations, as well as medical device standards. It is the ideal solution for businesses seeking high-value recycled PS materials.
Core Features & How It Solves Your PS Recycling Challenges
The PSG-800 is designed for high-precision applications, addressing the unique challenges of producing food-grade and medical-grade recycled PS:
- High Precision Pelletizing:Equipped with a precision die head and adjustable pelletizing system, the PSG-800 produces pellets with a size tolerance of ±0.1mm—ensuring uniform particle size, which is critical for food and medical applications where material consistency directly impacts product safety and performance.
- Low Impurity Content:A multi-stage filtration system removes 99.9% of impurities (e.g., metal, paper, other plastics), and a sealed processing chamber prevents contamination from dust, moisture, and external pollutants. This ensures the final pellets meet FDA and EU food-contact standards.
- Controlled Melting Temperature:A precise temperature control system (±5℃) maintains the optimal melting temperature (180-200℃) for PS, preventing thermal degradation and preserving the material’s mechanical properties—resulting in recycled PS pellets as strong and durable as virgin PS.
- Strict Compliance:The PSG-800 is FDA, CE, and ISO 13485 (medical device standard) certified, and fully compliant with PPWR regulations. It also meets EU Food Contact Materials (FCM) requirements, making it suitable for recycling PS waste from food and medical industries.
