PP PE Film Crushing Pelletizing Line
This line transforms post-industrial or post-consumer polypropylene (PP) and polyethylene (PE) films into high-quality recycled pellets. Designed for plastic films, agricultural mulch, and packaging waste, it removes contaminants like dirt, inks, and adhesives.
Product Description
This line transforms post-industrial or post-consumer polypropylene (PP) and polyethylene (PE) films into high-quality recycled pellets. Designed for plastic films, agricultural mulch, and packaging waste, it removes contaminants like dirt, inks, and adhesives.
The system combines crushing, washing, drying, and pelletizing stages to produce uniform pellets. These pellets are ideal for manufacturing new films, containers, or injection-molded products, supporting circular plastic economies.
Built for efficiency, the line emphasizes low energy consumption, minimal water use, and automation. It scales to handle capacities from 200–2,000 kg/h, catering to small recyclers and large facilities alike.
Key Features
High-Speed Crusher: Shreds films into flakes without tangling, even for lightweight materials.
Multi-Stage Washing: Pre-wash, friction wash, and hot wash remove oils, dirt, and surface contaminants.
Dewatering & Drying: Centrifugal spin dryers and thermal systems reduce moisture to <1%.
Pelletizing Extrusion: Twin-screw extruders melt flakes, filter impurities, and cut uniform pellets.
Material Flexibility: Processes both PP and PE films (LDPE, HDPE) with quick adjustments.
Closed-Loop Water System: Recycles water to cut consumption by 60–80%.
Dust Control: Integrated filters and airflow systems ensure clean operations.
Energy Recovery: Heat exchangers reuse thermal energy from drying stages.
Process Workflow
Sorting: Films are inspected to remove non-plastic debris (metals, paper).
Crushing: Shredded into 8–12 mm flakes for easier processing.
Pre-Washing: Removes loose dirt and sand with ambient water.
Friction Washing: High-speed scrubbers strip embedded contaminants and inks.
Hot Wash: Heated detergent dissolves adhesives and oils.
Rinsing & Dewatering: Flakes are rinsed and spun-dried.
Thermal Drying: Hot air dryers achieve moisture levels below 1%.
Pelletizing: Flakes are melted, filtered, and extruded into 2–5 mm pellets.
Cooling & Screening: Pellets are cooled and sorted by size.
Packaging: Stored in bulk bags or silos for industrial reuse.
