Introduction of plastic scrap granulator
As the global plastic pollution problem is getting more and more serious, the plastic scrap granulator becomes the core equipment of the plastic recycling industry chain. This machine converts waste plastics into reusable pellets through high temperature melting, extrusion and cutting processes, which are widely used in packaging, construction and automotive manufacturing. According to the United Nations Environment Programme (UNEP), only 9% of global plastic waste is effectively recycled, and the promotion of plastic scrap granulator can significantly increase this proportion.
Working principle and technical advantages of plastic scrap granulator
Core Workflow
Pre-processing: crushing, washing and drying. Pre-treatment: crushing, washing and drying of waste plastics.
- Melt Extrusion: Heat up to 180-300℃ by screw to melt the plastic.
- Filtration and moulding: remove impurities using plastic granulator screens and extrude strips of plastic.
- Cooling & Cutting: water or air cooling and then cut into uniform granules.
Technical Advantages
- Energy efficient: new motor reduces energy consumption by 20% (source: Plastics Recycling World).
- Multi-material compatibility: supports PE, PP, PVC and other plastics.
- Environmental protection and emission reduction: Reduces landfill incineration and lowers carbon emissions.
Global Market Trends and Equipment Selection Guide
International Market Trends
According to Grand View Research report, the global plastic scrap granulator market will reach USD 4.8 billion in 2023, with the fastest growth rate in Asia-Pacific region due to policy support.
Table: Comparison of Mainstream Equipment Parameters
Model | Capacity (kg/h) | Power (kW) | Applicable Materials |
Model A-2000 | 150-200 | 55 | PE, PP |
EcoGranulator | 300-350 | 75 | PVC, ABS |
GreenMax Pro | 500-600 | 110 | Mixed plastics |
Key factors for selection
- Capacity Matching: Selection of the model is based on the average daily processing capacity.
- Screen Configuration: The mesh size of the plastic granulator screen affects the purity of the granules.
- Brand Service: Choose a reputable plastic granulator manufacturers, such as Wintech, that offers lifetime maintenance.
Synergistic equipment and industry application cases
Synergy of stretch film rewinders
In the packaging industry, waste from stretch film machines can be recycled directly through waste plastic granulators. For example, a Wintech stretch film rewinding machine with a pelletiser can close the loop of ‘produce-recycle-pelletise’ and reduce raw material costs.
Successful Cases
- Automotive Manufacturing: A German automotive company uses a granulator to recycle bumper waste, saving 300 tonnes of new plastic per year.
- Agricultural film recycling: Indian farmers jointly purchased a small-scale pelletiser, increasing the conversion rate to 85%.
Maintenance tips and common problem solving
- Regular screen cleaning: clogging can lead to reduced capacity, it is recommended that plastic granulator screens be cleaned every 50 hours.
- Screw maintenance: apply high temperature resistant grease every month to extend service life.
- Troubleshooting: Uneven pellets? Check temperature settings or screen integrity.
Conclusion and future outlook
Plastic scrap granulator is not only a key tool for environmental transformation, but also a strategic choice for enterprises to reduce costs and increase efficiency. With technological iterations (e.g. AI intelligent temperature control system) and policy incentives, this equipment will accelerate the development of the global circular economy.
