Plastic Dana Plant Supplier in India

A Plastic Dana Plant converts post-consumer and post-industrial plastic waste into uniform granules (dana) for reuse in films, moulded parts, and sheets. A reliable supplier helps you select the right capacity, filtration level, degassing, and automation for LDPE, LLDPE, HDPE, PP, and mixed polyolefins. Evaluate energy consumption (kWh/kg), water usage, and maintenance support before purchase.

Working Principle & Process Flow

Typical dana lines include sorting, shredding/agglomeration, washing, drying, feeding, extrusion with melt filtration and vacuum degassing, followed by strand or die-face pelletizing and cooling. Density separation improves purity; hot-wash boosts adhesion and odour control; screen changers capture fines. SCADA records throughput, melt pressure, and temperatures for quality consistency and traceability.

Types of Plastic Dana Plants

Compact 120â€“250 kg/hr mono-stage extruder lines for LDPE/LLDPE film scrap and startup operations.
High-throughput 400â€“1200 kg/hr twin-degassing lines for printed/contaminated films and multilayer laminates.
PET bottle flake to r-PET pellet systems with hot-caustic washing, IV retention, and stainless contact parts.
Rigid regrind (HDPE/PP) plants with label removal, metal separation, friction washers, and intensive drying.
Odour-control and deodorizing add-on modules for post-consumer waste streams targeting FMCG applications.

Applications of Dana (Recycled Granules)

Film & packaging: carry bags, liners, shrink films, geomembranes with controlled MFI and haze values.
Moulding: crates, caps, buckets, pallets, and auto trims using rPP/rHDPE with impact and ESCR targets.
Textile & straps: r-PET chips into fibre/filament and PP/HD straps meeting tensile and elongation specs.
Infrastructure: pipes, fittings, sheets, and boards using blends of rPE/rPP tailored to end-use norms.

Why Partner with a Plastic Dana Plant Supplier

Lower material costs by converting scrap into saleable, spec-compliant granules; faster ROI with higher uptime.
Consistent quality via controlled washing, filtration, and degassing delivering stable MFI and colour.
Higher productivity with auto feeding, quick screen change, and pelletizing that reduces changeover losses.
Compliance & sustainability support for EPR documentation, audits, and ESG reporting.

Selection Guide for Buyers

Match plant capacity to steady scrap inflow and target customers. Specify polymer mix, contamination thresholds, and pellet specs (MFI, density, moisture, ash). Ask for layout drawings, utility charts, FAT protocols, warranty, and service SLAs. Consider water-recycling skids, deodorizing, stainless wetted parts, and automation upgrades for long-term reliability.

Maintenance & Safety Tips

Inspect knives, bearings, heaters, thermocouples, and screens; log vibration, amps, and melt pressure daily.
Maintain wash chemistry; replace contaminated water and clean tanks, pipes, and nozzles routinely.
Calibrate load cells, check vacuum levels, and verify MFI against production recipes per shift.
Train teams on lockout-tagout, hot-surface zones, and emergency stops; keep PPE and guards in place.
Stock critical spares (heaters, filters, seals) with traceable part numbers in dry storage.

FAQs â€“ Plastic Dana Plant Supplier

1. Which pelletizing method should I choose? +

Strand pelletizing is economical and versatile; water-ring die-face offers compact layout and uniform pellets; underwater is premium for narrow PSD and glossy finish. Choose based on polymer, throughput, and pellet quality targets.

2. What mesh size should I use for filtration? +

For relatively clean LDPE/LLDPE film, 100â€“120 mesh is typical. For printed/multilayer films, go 140â€“200 mesh with continuous screen changers and dual-degassing to control gels and black specks.

3. Can one line process both films and rigid regrinds? +

Yes, if equipped with proper feeding (forced/side), screw design, and filtration. However, dedicated lines or quick-change recipes reduce contamination carryover and stabilize pellet specs.

4. How do I control odour in post-consumer pellets? +

Use intensive washing, thermal conditioning, multi-zone vacuum, deodorizing additives, and post-treatment silos with aeration. Avoid overheating which can worsen smell and yellowing.

5. What utilities are required for a 500 kg/hr line? +

Three-phase power (as per motor list), process water for washing/cooling, compressed air for pneumatics, and ETP/WTP for recycling. Request a detailed utility chart from the supplier.
