What level of automation and technical support do you provide?

The system features centralized PLC control for real-time monitoring and adjustment. We provide comprehensive installation, commissioning, and operator training, backed by 24/7 remote support and a global spare parts network to maximize your uptime.

How energy-efficient is your granulation system compared to conventional models?

Equipped with permanent magnet motors and advanced electromagnetic heating, our system reduces energy consumption by up to 35% per ton of output compared to traditional setups, delivering a faster return on investment.

What is the key advantage of your closed-loop water circulation system?

Our closed-loop system recycles over 95% of process water, drastically reducing freshwater consumption and eliminating wastewater discharge. This not only cuts operational costs but also ensures full environmental compliance.

How does your system ensure the final pellet quality meets production standards?

 

Through a multi-stage process including friction washing, floating separation, and precision filtration, we achieve material purity exceeding 99%. The integrated degassing extruder removes moisture and volatiles, ensuring the pellets' mechanical properties meet manufacturing requirements.

What types of plastic waste is your system suitable for processing?

 

Our system is engineered to handle a wide spectrum of plastics, including PET bottles, HDPE containers, PP woven bags, and LDPE films. It effectively removes contaminants like labels, adhesives, and sand, transforming mixed waste into high-purity, reusable pellets.
