Agricultural Plastic Film Recycling Granulator

Product Overview

The agricultural plastic film recycling granulator is a specialized machine designed for the regeneration of used plastic films. Equipped with an advanced compaction and agglomeration feeding system, it efficiently converts loose, used plastic films into high-quality recycled plastic pellets after compacting and preheating. As a customized product, this equipment does not have a fixed price; it is tailor-made according to the customer’s production requirements. Originating from Nantong, the machine bears the PURUI trademark and brand name. Its core components are sourced from internationally renowned brands, ensuring stable and reliable performance. It can handle various types of waste plastic films, including agricultural greenhouse films, packaging stretch films, BOPP/CPP industrial films, courier plastic bags, heat-shrink films, and more, providing an efficient and energy-saving solution for waste plastic recycling.

Technical Principle

This granulator employs an integrated process combining a compactor and a single-screw extrusion system, creating a complete closed-loop workflow from waste film collection to regenerated pellets. First, the used plastic film does not require prior shredding and can be fed directly into the compactor (agglomeration hopper), where high-speed rotating blades cut and crush the material. Friction generated during rapid movement produces heat, naturally raising the temperature. The originally fluffy film contracts and compacts into uniform agglomerates, significantly increasing its bulk density, before being smoothly fed into the extrusion screw. In the extrusion stage, the material undergoes staged heating and shear action to achieve melting and plasticization. Multi-stage filtration removes impurities while simultaneously venting moisture and gases. Finally, water cooling and pelletizing produce high-quality recycled plastic pellets. Each step in the process is tightly coordinated, leveraging the material’s inherent frictional heat to enhance plasticization efficiency while reducing energy consumption.

Core Advantages

1. Compactor feeding system: Featuring a compacting and agglomeration design, this system effectively prevents loose films from becoming airborne or slipping during feeding, ensuring more uniform material input and maintaining stable, continuous production without requiring additional manual adjustments to the feeding rhythm.
2. Self-friction preheating for energy savings: The material achieves self-heating through high-speed friction within the compactor, resulting in higher plasticization efficiency upon entering the extrusion stage. Compared to conventional granulators, this approach saves over 15% of electricity per ton processed.
3. Elimination of pre-shredding: The equipment can accept whole rolls or bundles of used plastic film without prior shredding, removing the need for a separate crushing step, reducing labor by 1–2 workers, and cutting both labor costs and processing time.
4. Efficient venting and dehumidification: An advanced venting and dehumidification process effectively removes moisture and impurities, producing clean, bubble-free recycled pellets with a defect rate kept below 3%, meeting the stringent quality standards required for high-grade recycled plastics.
5. Stable and controllable output: With standard models ranging from 100 to 1500 kg/h, the machine can produce up to 36 tons per day under 24-hour operation. Any edge trimmings generated during production are fully recycled back into the process, maximizing resource utilization.

Core Value of the Product

1. Simplified processes reduce costs: By eliminating the pre-shredding step and minimizing labor input, the overall cost of production and processing is lowered, enhancing the economic viability of recycling operations.
2. Energy-efficient, high-performance production: Leveraging self-friction preheating to boost plasticization efficiency, the machine significantly cuts electricity consumption, delivering substantial long-term savings while maintaining high, stable output.
3. High-quality recycled pellets: Produced pellets feature low moisture content, no bubbles, excellent appearance, and a defect rate below 3%, making them suitable for direct use in manufacturing various plastic products and increasing the value of recycled resources.
4. Customizable solutions: Tailored to meet specific production needs, the equipment flexibly adapts to businesses of different scales, addressing diverse scenarios in waste plastic film recycling.

Target Customer Groups

This equipment primarily serves plastic film manufacturers, waste plastic recycling plants, packaging material companies, and resource recovery enterprises—businesses that generate large quantities of used plastic films requiring proper disposal. With its efficient, energy-saving, and high-quality output, the machine perfectly aligns with their operational needs, helping them achieve circular use of waste resources while improving both economic and environmental benefits.

Application Scenarios

This equipment is suitable for recycling and regenerating various types of waste plastic films, including post-season recovery of agricultural greenhouse films, collection of leftover stretch film from the packaging industry, recycling of BOPP/CPP industrial films produced during manufacturing, handling vast quantities of discarded courier plastic bags, and processing heat-shrink films and other waste plastic materials. Whether operating small-scale recycling workshops or large-scale resource recovery facilities, customers can customize models to match their specific production capacities, achieving efficient transformation of waste plastic films.

Solutions to Industry Pain Points

1. Solving the challenge of feeding loose films: Traditional granulators often suffer from issues like loose films becoming airborne or feeding unevenly. The compactor feeding system of this machine compresses loose films into uniform agglomerates, ensuring steady, consistent feeding and uninterrupted production.
2. Eliminating the cost of pre-shredding: Conventional recycling requires preliminary shredding, adding extra steps and labor. This equipment accepts whole rolls or bundles directly, saving on both labor and time.
3. Enhancing plasticization efficiency and output: Addressing the problem of insufficient plasticization and low productivity in traditional machines, this equipment uses self-friction preheating to raise material temperature, combined with screw shearing for melting and plasticization, dramatically boosting efficiency and enabling higher output—up to 36 tons per day under 24-hour operation.
4. Reducing defects in wet-material granulation: Traditional equipment tends to produce pellets with numerous air bubbles and high defect rates when processing moist materials. This machine’s multi-stage venting and dehumidification system effectively removes moisture, keeping finished pellet moisture content at ≤0.3%, free of bubbles, and limiting defect rates to below 3%, thus elevating product quality.
