PP Dana Making Machine

Introduction 

A PP Dana Making Machine converts polypropylene scrap—raffia/woven sack waste, non-woven, film trims, injection regrind—into uniform granules (dana) for tapes, sheets, films, and moulded parts. A complete line integrates crushing/agglomeration, vented extrusion, melt filtration, and water-ring or die-face pelletizing to achieve consistent MFI, colour, and pellet geometry. When shortlisting partners in India, compare throughput (kg/hr), energy (kWh/kg), filtration strategy, degassing, and after-sales coverage. Explore line options and layouts on HR Plastic India.


Working Principle and Process Flow of a PP Dana Line

Sorted PP scrap is size-reduced and, if required, washed and dried. A cutter–compactor or force-feed stabilizes bulk density for steady screw feed. In the extruder, vacuum venting removes volatiles and moisture; the melt passes through hydraulic/continuous screen changers before pelletization via water-ring or die-face hot cutting. PLC/SCADA logs throughput, energy, alarms, and recipes for traceability and repeatability. Learn modular configurations on hrplasticindia.com.


Types of PP Dana Making Machines

  • Monolayer vented extruder (150–350 kg/hr): For clean raffia/offcuts and sorted injection/film regrind.
  • Two-stage extruder with twin venting (300–1000 kg/hr): For printed/ink-laden or odour-prone PP with higher contamination.
  • Cutter–compactor/force-feed lines: Densifies light film/non-woven to stabilize amps and raise output.
  • Water-ring pelletizer systems: Compact layout, fast start/stop, uniform spherical pellets.
  • Strand pelletizer lines: Simple to maintain, tolerant to water-quality variation, robust knives.

Key Features & Specifications

  • Energy-efficient motors with VFDs; documented kWh/kg for cost benchmarking.
  • Vacuum degassing, multi-zone barrel heating, precise melt temperature control.
  • Automatic screen changer (hydraulic/back-flush/continuous) for stable pressure and fewer gels.
  • Bi-metallic barrels, nitrided/EN41B screws; optional gear pump for pressure stability.
  • PLC–SCADA with recipe control, alarm logs, preventive maintenance prompts, remote diagnostics.
  • Additive/masterbatch dosing for odour control, UV/antioxidant stabilization, colour consistency.
  • Water-ring/die-face or strand pelletizer with auto knife advance for consistent dana size.

Applications of PP Dana

  • Woven-sack/raffia tape lines (denier stability, tensile/elongation targets).
  • Non-woven (spunbond) back-to-granule loops with strict filtration and odour control.
  • Sheet & thermoforming for trays, PP stationery, and automotive liners.
  • Injection moulding of crates, caps/closures, and household components.
  • Fluted boards, monofilament ropes, and extrusion coating substrates.

Benefits of a PP Dana Making Machine

  • Lower raw-material cost with consistent recycled PP granules and stable MFI.
  • Higher productivity via force-feed/agglomeration, continuous screen change, and automated pelletizing.
  • Improved quality through vacuum venting, fine filtration, and recipe repeatability.
  • Compliance & traceability support (EPR alignment, SCADA data, safety guarding).

Manufacturers & Suppliers in India

Specialized Indian manufacturers supply turnkey PP dana machines—layout design, utilities, installation, commissioning, operator training, and spares. Request FAT data under varied feed conditions (raffia/non-woven/film), targeted pellet specs (MFI, ash, contamination ppm), and odour benchmarks. Consider water-recycling, deodorizing, gear pump integration, and quick-change dies to cut transition losses. Service coverage across Ahmedabad, Mumbai, Delhi-NCR, Coimbatore, and Hyderabad is common.


Maintenance and Safety Tips

  • Monitor screw/barrel wear, gearbox oil, and motor amps; log temperatures and vibration daily.
  • Keep knives sharp and pelletizer clearances calibrated; check water-ring/strand bath parameters.
  • Calibrate melt pressure/temperature sensors; verify MFI and colour every shift against targets.
  • Practice lockout–tagout; shield nip points and hot zones; test emergency stops routinely.
  • Maintain critical spares—screens, heaters, thermocouples, knives, seals—with traceable SKUs.


FAQs – PP Dana Making Machine

1. What capacity should I choose? +
Align kg/hr with steady scrap availability, shifts, and downstream demand. For printed/non-woven feeds, size up degassing and filtration to keep output and pellet quality stable.
2. Water-ring vs die-face vs strand—what’s better for PP? +
Water-ring is compact with uniform pellets and quick start/stop; die-face hot cutting suits higher throughputs and frequent recipe changes; strand is simpler to maintain and tolerant to water variation.
3. How do I manage odour and inks in PP recycling? +
Use effective washing/drying, strong vacuum venting (two-stage if needed), longer L/D, and deodorizing additives. Post-conditioning of pellets further reduces residual odour.
4. How do I control MFI consistently? +
Control feed mix, maintain stable melt temperature, and use gravimetric dosing for flow modifiers. Log batch MFI and adjust recipes to meet downstream tape/film specifications.
5. What utilities are required? +
Three-phase power, process/chilled water for washing and cooling, and compressed air. Plan for water recycling/ETP and backup power to stabilize production.
