Two Stage Plastic Recycling Plant
Searching for a dependable two stage plastic recycling plant for film, flakes and mixed post-consumer waste? HR Plastic India engineers high-degassing pelletizing lines that stabilize MFI, remove moisture/ink volatiles and deliver uniform pellets for converters across India and export markets.
Working Principle and Process Flow
A two stage recycling plant combines a primary vented extruder with a secondary extruder. The first stage provides intensive plasticizing, melt filtration and vacuum degassing; the second stage polishes the melt, equalizes pressure and feeds the pelletizer. With force-feed hoppers, crammer feeders and automatic screen changers, the line handles printed films, washed agri-film, and light-density fluff with consistent output.

Types of Two Stage Lines We Offer
- Vent–Vent (Dual Vacuum) Lines for high-moisture films and odour-sensitive packaging waste.
- Vent–No-Vent Lines for moderately contaminated regrind with downstream melt-pump integration.
- Water-Ring Die Face Cutter systems for uniform spherical pellets and high throughput in PE/PP.
- Strand Pelletizer setups for engineering plastics and controlled pellet length distribution.
- Compounding-Ready Packages with gravimetric dosing, side feeders and masterbatch/filler capability.
Key Features & Specifications
- Dual vacuum ports with condensers to strip moisture and volatiles from printed films.
- Automatic screen changers (hydraulic/continuous) for steady pressure and fewer black specks.
- Hardened screw & barrel metallurgy, multi-zone heating and precise temperature control.
- Optional melt pump for pressure stability and finer filtration (up to 120+ mesh stacks).
- PLC-SCADA with recipes, alarms, energy logs and remote diagnostics; documented kWh/kg.
Applications
- Washed LDPE/LLDPE agri-film and packaging film conversion to rPE pellets for films, liners and molding.
- rPP from woven sacks, raffia and injection regrind for non-critical automotive/appliance components.
- Mixed post-consumer streams stabilized via dual degassing for reliable downstream extrusion/coating.
- Filler/MB compounding lines for CaCO₃/talc functionalization with controlled MFI and dispersion.
Benefits of Two Stage Plastic Recycling Plants
- Superior degassing—reduced odour, moisture and ink volatiles for stable melt quality.
- Consistent pellets—pressure-balanced second stage improves size and MFI repeatability.
- High uptime—auto screen changers, robust metallurgy and standardized spares.
- Lower operating cost—optimized screw design and energy-logged kWh/kg benchmarks.

FAQs – Two Stage Plastic Recycling Plant
1. When should I choose a two stage line over single stage?
+
When feed has higher moisture/inks (printed films, washed agri-film) or when you need tighter MFI control and odour reduction. Dual degassing stabilizes quality.
2. What pelletizer is best—water-ring or strand?
+
Water-ring suits PE/PP films and high throughput with spherical pellets; strand works well for engineering plastics and when you need fixed pellet length.
3. Can I integrate filler or masterbatch dosing?
+
Yes—side feeders and gravimetric dosing integrate with the second stage for MB/filler compounding and recipe repeatability.
4. What filtration levels are typical?
+
For washed films, dual-stage 60–120 mesh is common; add continuous screen changers and optional melt pump for tighter specs and fewer black specks.
5. Do you provide installation and after-sales support?
+
We provide installation, commissioning, operator training, preventive maintenance schedules, remote diagnostics and guaranteed spares with response-time SLAs.
