Recycled Dana Making Machine – Plastic Recycling Extruder & Pelletizing Line
A Recycled Dana Making Machine converts post-consumer and post-industrial plastic scrap into uniform granules (dana) ready for film blowing, injection moulding, sheet and pipe extrusion. A complete line typically includes feeding, shredding/agglomeration, extrusion with filtration and degassing, pelletizing, drying and silo storage. Buyers in India should balance throughput (150–1500 kg/hr), polymer types (LDPE/LLDPE/HDPE/PP/PET), power and water needs, and after-sales coverage. Use this page to compare configurations, features and maintenance practices before investing.
Working Principle & Process Flow
Scrap is size-reduced and homogenised, then conveyed to a single or twin-stage extruder. Inside the barrel, controlled heating and shear melt the plastic while vacuum vents remove moisture and volatiles. Melt passes through a screen changer to capture contaminants before being cut into pellets via water-ring, die-face or strand cutting. A closed-loop water system cools and dries the pellets; PLC/SCADA logs kWh/kg, melt pressure and temperature for quality traceability. Explore line options and service support on Hr Plastic India.
Types of Recycled Dana Lines
- Single-Stage Vented Extruder (LD/LLD/HD/PP): For relatively clean film/rigid regrind; vacuum venting controls moisture and odour.
- Two-Stage Extruder (Agglomerator + Extruder): Handles highly printed, moist or mixed film with improved filtration stability.
- Compactor/Force-Feed Film Line: Infeed compactor densifies fluffy film; ideal for shopping bags, liners and stretch film.
- PET Pelletizing with IV Control: Hot-wash + twin-vacuum degassing for rPET flakes aimed at fibre/strap applications.
- Rigid Regrind Line (HDPE/PP crates, drums): Includes metal separation, label removal and intensive washing modules.
Key Features & Specifications
- Output: 150–300, 400–800, 900–1500 kg/hr models with documented kWh/kg benchmarks.
- Screw & Barrel: Nitrided/bi-metallic; L/D 28–36; specialised mixing for colour and MFI stability.
- Filtration: Manual/auto screen changer, 80–200 mesh; pressure sensors with alarm logs.
- Degassing: Single or twin vacuum vents with condensate traps to reduce gels/odour.
- Pelletizing: Water-ring, die-face hot-cut or strand; auto cutter speed sync for uniform size.
- Drives & Controls: IE3 motors, VFDs, PLC-HMI with recipe storage, remote diagnostics.
- Material Contact: SS304 for wash tanks, piping and critical PET contact parts.
- Utilities: Three-phase power, closed-loop water circuit, optional ETP for effluent compliance.
Applications of Recycled Dana
- Film converters for garbage bags, liners, mulch films and carry bags with controlled MFI and haze.
- Injection moulding of household items, crates, caps, automotive trims and appliance parts.
- Pipe and corrugated hose production using rHDPE/rPP blends meeting stiffness and impact targets.
- Thermoformed trays and sheets where colour and thickness uniformity are essential.
- Textile/fibre and strapping from rPET where tensile strength and IV retention are critical.
Benefits of a Modern Dana Making Machine
- Lower raw-material costs by converting in-house scrap and purchased waste into consistent pellets.
- Stable quality with multi-stage filtration, recipe control and vacuum degassing for fewer rejections.
- Higher uptime via auto screen change, robust compaction feed and standardised spares.
- Traceability and compliance enabled by SCADA logs, safety guarding and EPR-friendly reporting.
- Modular upgrades—bigger die, extra vent, water-ring to die-face—without changing plant layout.
Manufacturers & Suppliers in India
India hosts established manufacturers for film, rigid and PET pelletizing lines. When comparing vendors, review their reference installations, achievable kWh/kg, filtration area, vacuum performance and after-sales footprint. Typical deliverables include layout/utility drawings, installation & commissioning, operator training, spare kits and remote support. Locations with strong service networks include Ahmedabad, Mumbai, Delhi-NCR, Coimbatore and Hyderabad. Request FAT protocols and acceptance guarantees aligned to throughput, contamination and pellet uniformity targets.
Maintenance & Safety Tips
- Track bearing temperatures, gearbox oil, vacuum levels and melt pressure; log deviations daily.
- Clean water tanks, strainers and heat exchangers; maintain TDS and biocide levels in the loop.
- Inspect screens and breaker plates; calibrate load cells and temperature sensors per schedule.
- Follow LOTO procedures; guard rotating cutters and hot zones; keep eyewash and PPE accessible.
- Stock critical spares: heaters, thermocouples, gear couplings, seals, knives and screen packs.
