HDPE LDPE Reprocessing Machine Supplier
Looking for a trusted HDPE/LDPE reprocessing machine supplier in India? Get robust pelletizing lines for film and rigid scrap—covering crushing, washing, drying, extrusion, filtration, and die-face cutting. Choose systems with proven kWh/kg benchmarks, stable output MFI, low gels, and nationwide service support to keep your line profitable and compliant.
Working Principle and Process Flow of Reprocessing Lines
Typical HDPE/LDPE reprocessing follows: sorting → shredding/granulation → washing & friction cleaning → centrifuge drying → agglomeration/compaction (for films) → extruder with vacuum degassing → melt filtration → pelletizing → silo cooling. Density separation enhances purity; screen changers stabilize pressure; SCADA logs throughput for traceability. Learn modular configurations on hrplasticindia.com.
Types of HDPE/LDPE Reprocessing Machines
- Compact film recycling lines (150–300 kg/hr) with integrated compactor for LDPE/LLDPE carry-bags and laminates.
- Medium-scale twin-vent extruders (400–800 kg/hr) for mixed post-consumer LDPE, maintaining stable MFI and color.
- High-throughput reprocessing plants (1000–1500 kg/hr) with continuous screen changers and auto-feeding systems.
- Rigid HDPE regrind lines with hot wash, label/metal removal, and multi-stage filtration for drums, crates, and caps.
- Odour-control & deodorizing modules for post-consumer film to improve pellet acceptability in packaging and liners.
Key Features and Specifications
- IE2/IE3 motors with VFDs and documented specific energy (kWh/kg) for predictable operating cost.
- Degassing zones, melt pumps, and automatic/continuous screen changers to minimize gels and pressure spikes.
- Die-face cutter or strand pelletizer options; water-ring for films, strand for rigid regrind and higher IV control.
- Stainless steel (SS304) contact parts in wash modules; closed-loop water recycling to reduce effluent load.
- PLC-SCADA with recipes, alarms, preventive maintenance prompts, and remote diagnostics for faster support.
Applications of Reprocessed HDPE/LDPE
- Blown film for liners, garbage bags, and shrink wraps with specified dart impact, COF, and printability parameters.
- Injection moulded components—crates, pails, caps, houseware—using blends of rHDPE/rLDPE with virgin resins.
- Pipe and conduit (non-pressure) with controlled MFI and carbon black dosing for UV stability and stiffness.
- Extruded sheets/laminates for thermoforming trays and protective packaging with consistent thickness tolerance.
Benefits of Partnering with a Specialist Supplier
- Lower cost per kg via energy-efficient drives, optimized heating zones, and stabilized melt quality reducing rejections.
- Higher uptime with standardized spares, fast screen changes, and remote diagnostics that shorten troubleshooting time.
- Quality compliance—traceable lots, moisture control, and filtration fineness supporting brand audits and EPR goals.
- Scalable architecture: add wash tanks, extra filtration, or pelletizing upgrades without redesigning the full plant.
Manufacturers & Suppliers in India
India’s ecosystem spans specialized plastic recycling OEMs and turnkey integrators. While comparing suppliers, evaluate film handling (agglomeration vs. force-feed), filtration mesh sizes, degassing efficiency, pellet uniformity, and after-sales coverage. Typical deliverables include layout engineering, erection & commissioning, training, and warranty with defined response times. Popular hubs include Ahmedabad, Mumbai, Delhi-NCR, Hyderabad, and Coimbatore—offering faster spares and service visits.
Maintenance and Safety Tips
- Track gearbox oil, bearing temps, and vibration; replace knives/screens per hour-based schedule.
- Maintain wash chemistry and TDS; desludge tanks and clean friction washers to prevent fines carry-over.
- Calibrate pressure, melt temperature, and load-cell feeders; log MFI and color ΔE for every lot.
- Use lockout-tagout; guard moving parts and hot surfaces; verify emergency stops monthly.
- Stock heaters, thermocouples, seals, and pelletizer blades; keep spares dry and labelled.
FAQs – HDPE LDPE Reprocessing Machine Supplier
1. What capacity should I choose for LDPE film reprocessing?
+
Size your line to consistent scrap inflow, available shifts, and target customers. For decentralised collection, 200–400 kg/hr is ideal; central facilities often start at 600–1000 kg/hr with twin-vent extruders.
2. Which pelletizer is better—water-ring or strand?
+
Water-ring suits films and low MFI LDPE with good pellet roundness and cooling. Strand pelletizers are preferred for rigid HDPE regrind and tighter pellet size control.
3. How do I control odour in post-consumer film?
+
Use hot wash with detergents, friction cleaning, twin-vent degassing, and deodorizing modules. Dry and store feedstock properly to limit bacterial odours.
4. What utilities are required?
+
Three-phase power, process water for wash/cooling, and compressed air. Plan for water recycling, ETP, and stabilised power during peak demand or monsoon outages.
5. What documentation should a supplier provide?
+
P&ID/layouts, utilities list, FAT protocols, performance guarantees (throughput, kWh/kg, filtration), manuals, and preventive maintenance schedules with spare part lists.
