Two Stage Plastic Recycling Plant Supplier
Find reliable mother–baby extruder lines that turn mixed, washed plastics into clean, consistent granules. As a specialist Two Stage Plastic Recycling Plant Supplier in India, we help you size, configure, and automate systems for LDPE films, HDPE rigs, PP raffia, and more. Expect stable output, low gels, and better odour control with vacuum degassing and fine filtration. Explore layouts, utilities, and upgrade paths on hrplasticindia.com.
Working Principle and Process Flow of Two Stage Lines
Two stage (mother–baby) plants pair a primary extruder for heavy melting and degassing with a secondary extruder for final filtration and pelletizing. The flow typically is: sorting and size reduction, wash and dry, agglomeration or densifying, first-stage extrusion with vacuum, screen change, melt transfer to second stage, fine filtration, and die-face or strand pelletizing. Recipe control and SCADA improve repeatability and traceability.
Two Stage Plant Configurations
- Film recycling mother–baby lines for LDPE/LLDPE carry-in moisture and inks, featuring forced feeding and long L/D ratios.
- Rigid HDPE and PP lines with label removal, metal separation, and hot-wash compatibility for drums, crates, and housings.
- PET washing plus extrusion modules with IV management where non-food rPET chips or pellets are targeted.
- High throughput tandem systems for 800–1500 kg/hr with twin venting and continuous screen changers.
- Compact modular sets for 150–300 kg/hr suited to decentralized scrap aggregators and municipal projects.
Key Features and Specifications
- Primary extruder with deep vacuum degassing to cut odour and volatiles from post-consumer streams.
- Automatic or continuous screen changers; fine filtration up to 80–120 mesh for low gels and specks.
- Multi-zone barrel heating, VFDs, and documented kWh/kg for predictable operating costs.
- PLC–SCADA with recipe save, alarms, preventive maintenance prompts, and remote diagnostics.
- Bolt-on upgrades: stainless contact parts, water-recycling, odour-control, and higher capacity motors.
Applications of Two Stage Recycling Plants
- Packaging converters producing films, sheets, and moulded parts with rPP/rPE that meet brand MFI and colour targets.
- Textile, strapping, and fiber producers consuming rPET and rPP pellets with tensile and elongation stability.
- Automotive and appliance suppliers using rPP, ABS, HIPS for non-critical trims, ducts, and interior parts.
- Municipal and industrial waste handlers converting mixed streams into saleable pellets aligned with EPR goals.
Why Choose a Two Stage Plastic Recycling Plant
- Cleaner melt with fewer gels due to staged filtration and strong vacuum, improving downstream quality and yield.
- Higher productivity from automated dosing, stable feeding, and fast screen changes that reduce unplanned stops.
- Lower lifecycle cost through energy-efficient drives, robust wear parts, and pan-India service coverage.
- Better compliance and ESG reporting with batch traceability, safety guarding, and water-recycling options.
Manufacturers and Suppliers in India
India hosts proven suppliers of two stage plastic recycling plants with experience in local scrap profiles and chemistry. Standard deliverables include layout design, installation, commissioning, operator training, spares, and remote support. Compare vendors on documented energy benchmarks, pellet quality metrics, and service response. For assistance, review sample P&IDs, utility charts, and performance guarantees aligned to throughput, contamination, and moisture limits.
Maintenance and Safety Tips
- Log bearing temperature, vacuum levels, motor loads, and melt pressure; investigate abnormal trends early.
- Keep wash tanks and piping clean; maintain chemical concentration and replace water when contaminated.
- Calibrate sensors, load cells, and temperature zones; verify MFI against target before long runs.
- Train teams on lockout–tagout, hot surfaces, confined spaces, and emergency stop procedures.
- Stock critical spares like heaters, thermocouples, seals, and screens with traceable part numbers.
FAQs – Two Stage Plastic Recycling Plant Supplier
1. When is a two stage (mother–baby) line better than a single stage extruder?
+
Use a two stage system when input contamination and odour are high or when very fine filtration is needed. The first stage handles heavy degassing, while the second stage finishes filtration and pelletizing for cleaner, more consistent output.
2. What capacities are typical for film and rigid plastics?
+
Compact modules start around 150–300 kg/hr for film. Industrial lines range from 600–1500 kg/hr depending on polymer type, washing quality, and mesh size. Final capacity depends on moisture, contamination, and recipe.
3. Which utilities should we plan for?
+
Three-phase power, process water for washing and cooling, and compressed air are typical. Many buyers add water-recycling and ETP units plus gensets to reduce grid-related interruptions.
4. Can the same line process mixed municipal plastics?
+
Yes, with pre-sorting and density separation. For consistent pellet specs, run separate loops for different polymer families and use appropriate filtration and venting settings.
5. What contract terms should I request from suppliers?
+
Seek installation and commissioning, operator training, preventive maintenance schedules, remote diagnostics, and guaranteed response times. Ask for performance guarantees tied to throughput, moisture, and contamination limits.
