LDPE Reprocessing Machine Supplier
As a trusted LDPE reprocessing machine supplier in India, we help processors convert post-consumer and post-industrial LDPE films into high-quality recycled granules. Our lines cover shredding/agglomeration, degassing extrusion, melt filtration, and pelletizing to deliver consistent MFI and colour with low energy per kg. We size plants to your scrap profile, utilities, and compliance needs, focusing on uptime, automation, and lifecycle cost.
Working Principle & Process Flow of LDPE Reprocessing
Typical LDPE reprocessing follows: inspection & sorting → size reduction/agglomeration → hot & cold washing (as needed) → drying → extruder with multi-zone heating & vacuum degassing → automatic screen changer filtration → pelletizing (die-face or strand) → cooling → drying & siloing. For flexible films, force-feed extruders stabilize throughput; gravimetric dosing ensures recipe accuracy. Learn more on hrplasticindia.com.
Types of LDPE Reprocessing Lines We Supply
- Compact Start-Up Lines (150–300 kg/hr): For decentralized aggregators and MSMEs handling clean packaging film offcuts.
- Standard Film Recycling Plants (300–800 kg/hr): With agglomerator/compactor, force-feed extruder, and die-face cutter for mixed film streams.
- High-Throughput Twin-Line Systems (800–1500 kg/hr): Redundant operation, reduced changeovers, and continuous production during maintenance.
- Wash+Reprocess Lines: Hot caustic/friction washing modules for printed, dusty, or lightly contaminated LDPE.
- Odour-Control & De-inking Options: Add-ons for monsoon-affected bales and high-print laminates.
Key Features & Specifications
- Energy-efficient motors with VFDs; documented kWh/kg benchmarks for cost prediction.
- Force-feed extruder, vacuum degassing, and automatic screen changer to reduce gels and black specs.
- Multi-zone heating, melt pressure/temperature monitoring, and online MFI sampling for consistent quality.
- PLC-SCADA with recipe control, alarm logs, and remote diagnostics for faster troubleshooting.
- Bolt-on capacity expansion, standardized spares, and pan-India service network for high uptime.
Applications of LDPE Reprocessed Granules
- Liner & Carry Bags: Controlled MFI for film blowing, with good seal strength and printability (subject to state guidelines).
- Garbage/Utility Bags & Stretch Films: Balanced elongation and dart impact for municipal and industrial use.
- Agri Mulch & Tunnel Films: Recipes tuned for UV stability and tear resistance.
- Plastic Furniture & Injection Parts: rLDPE blends for non-critical moulded components and profiles.
- Protective Packaging: Foam/lamination layers, bubble film cores, and cushioning sheets.
Benefits of Partnering with an LDPE Reprocessing Machine Supplier
- Lower Material Cost: Convert scrap to value; predictable OPEX with documented energy figures.
- Stable Quality: Multi-stage filtration and degassing ensure uniform MFI/colour and fewer rejections.
- Higher Productivity: Automated dosing, quick screen changes, and robust conveying reduce downtime.
- Compliance & Traceability: SCADA logs, EPR alignment, and safety guarding support audits and ESG reporting.
Manufacturers & Supplier Considerations in India
When selecting an LDPE reprocessing partner, compare experience with local film scrap (printed, laminated, washed), pellet quality metrics, and proven throughput on similar inputs. Deliverables should include layout, installation & commissioning, operator training, critical spares, and remote diagnostics. Common upgrades: stainless contact parts, water-recycling/ETP, odour control, and silo automation. Seek FAT documentation and performance guarantees linked to contamination, kg/hr, and pellet specs.
Maintenance & Safety Tips
- Inspect knives, screens, bearings, belts daily; record vibration/noise/temperature trends.
- Maintain wash chemistry and replace contaminated water; clean tanks, pipes, and nozzles routinely.
- Verify melt pressure, heater zones, and target MFI; calibrate sensors and load cells on schedule.
- Train operators on lockout-tagout, hot surfaces, confined spaces, and emergency stops.
- Stock critical spares—heaters, thermocouples, seals, screens—stored dry with traceable part numbers.
FAQs – LDPE Reprocessing Machine Supplier
1. What capacity should I choose for LDPE reprocessing?
+
Match capacity to steady scrap availability, planned shifts, contamination levels, and downstream demand. Modular designs allow scaling without compromising washing or filtration performance.
2. Which pelletizing method is better—die-face or strand?
+
For thin LDPE films, die-face cutting offers stable granule size and simpler handling. Strand pelletizing suits cleaner feed and when lower equipment cost is a priority. Choice depends on input quality and product specs.
3. Can one line handle mixed LDPE/LLDPE films?
+
Yes, with proper segregation and recipe control. Force-feed extruders, vacuum degassing, and suitable filtration help maintain consistent MFI and reduce gels caused by inks and contaminants.
4. What utilities are required?
+
Three-phase power, process water (if washing), and compressed air. Plan for water recycling/ETP, gensets for grid fluctuations, and adequate space for bale storage and finished pellet silos.
5. How do you ensure consistent pellet quality?
+
Through controlled heating profiles, vacuum degassing, fine-mesh filtration via automatic screen changers, and periodic lab checks for MFI, colour, moisture, and contamination levels.
