PS Granulator
Polystyrene (PS) waste—including expanded polystyrene (EPS), rigid polystyrene (RPS), and PS foam—poses unique challenges in recycling due to its low density, high volume, and dust-generating nature during processing. The PSG-1200 High-Capacity PS Granulator is specifically engineered to tackle these pain points, efficiently converting PS waste into high-quality regrind and pellets that can be reused in manufacturing new plastic products—from packaging materials to industrial components. As a professional PS recycling machine, it integrates crushing, melting, and pelletizing functions into a seamless line, enabling manufacturers to reduce waste disposal costs, comply with PPWR regulations, and achieve sustainable production objectives.
Core Features & How It Solves Your PS Recycling Challenges
The PSG-1200 PS granulator is built for industrial-scale efficiency and reliability, focusing on addressing the key pain points of recycling facilities and plastic manufacturers:
- Low Dust Emission:Equipped with a built-in dust collection system and sealed crushing chamber, the machine reduces dust leakage by 95% compared to standard granulators. This not only enhances workplace safety but also prevents dust contamination of the final regrind, ensuring high-quality output that meets ISO 9001 standards.
- High Output Capacity:Featuring an optimized rotor design and powerful motor, the PSG-1200 delivers a stable output of 500-800 kg/h—ideal for large-scale PS waste processing. This eliminates the low-efficiency bottleneck that plagues small-scale granulators, helping businesses scale their recycling operations effectively.
- Energy-Saving Technology:Integrated with an inverter control system and high-efficiency motor, the machine cuts energy consumption by 18-25% compared to traditional PS recycling machines. For facilities processing 10 tons of PS waste daily, this translates to annual energy savings of over $15,000.
- Versatile Compatibility:The PSG-1200 works seamlessly with all types of PS waste, including EPS foam, PS bottles, PS sheets, and manufacturing scrap. Its adjustable screen mesh size (1-5mm) allows customization of pellet diameter, meeting the diverse needs of downstream production.

FAQ (Frequently Asked Questions)
- How to choose a PS granulator for large-scale PS waste recycling?
Opt for a granulator with high motor power (30+ kW), a large rotor diameter (≥250mm), and adjustable output capacity (500+ kg/h). The PSG-1200 is ideal, as it combines high efficiency, low energy consumption, and dust control, fully complying with industrial recycling standards. - What is the difference between dry and wet plastic granulation for PS?
Dry granulation—used in the PSG-1200—is ideal for PS waste with low moisture content, requiring less water and reducing environmental impact. Wet granulation uses water for pellet cooling but increases energy use and requires wastewater treatment, making dry granulation more cost-effective for PS recycling. - Can the PSG-1200 process EPS foam efficiently?
The machine includes a pre-crushing module that compresses EPS foam to reduce volume, then crushes and pelletizes it into high-density regrind at 500-600 kg/h—significantly more efficient than standard granulators. - How to maintain the PS granulator for long service life?
Regularly inspect and replace tungsten carbide blades every 6-8 months, clean the screen mesh weekly, and lubricate rotor bearings monthly. We provide a 1-year warranty and on-site maintenance to ensure stable operation.
Why It Matters (Core Benefits for Your Business)
In today’s strict environmental regulatory landscape (including PPWR) and growing demand for sustainable materials, investing in a high-quality PS recycling machine is a strategic decision. The PSG-1200 PS granulator helps your business: 1) Cut PS waste disposal costs by 70% by reusing waste as raw material; 2) Generate additional revenue by selling high-quality PS pellets to plastic manufacturers; 3) Enhance your brand image as an eco-friendly enterprise, attracting environmentally conscious clients; 4) Reduce carbon emissions and energy use, aligning with global sustainability goals.
