Plastic Granule Plant Manufacturer

Plastic Granule Plant Manufacturer in India | High-Output Granulation Lines

Plastic Granule Plant Manufacturer

A plastic granule plant converts clean or mixed plastic scrap into uniform granules with controlled melt flow for film, molding, and fiber applications. As a manufacturer in India, we engineer washing, extrusion, filtration, and pelletizing modules to suit LDPE, LLDPE, HDPE, PP, PET, HIPS, and ABS. Our focus is stable throughput, low kWh/kg, consistent pellet size, and simplified maintenanceâ€”helping processors achieve repeatable quality and faster ROI.

Working Principle and Process Flow of Plastic Granule Plants

Typical lines include sorting, size reduction, washing, drying, feeding, extrusion with filtration and degassing, and final pelletizing. Density separation raises purity; vacuum vents strip volatiles; screen changers capture fines. SCADA logs energy and throughput for traceability and preventive maintenance. Match design to scrap variability, moisture, and target MFI. Learn modular configurations and upgrades on hrplasticindia.com.

Types of Plastic Granule Plants We Offer

Compact single-stage granulation lines (120â€“300 kg/hr) for relatively clean LDPE/LLDPE film and regrind.
Two-stage (mother-baby) degassing lines (300â€“900 kg/hr) for printed film, foils, and moisture-laden inputs.
High-throughput twin-line systems (800â€“1500 kg/hr) enabling redundancy and reduced changeovers.
PET bottle wash + pelletizing with hot caustic modules, friction washers, and IV-retention options.
Rigid plastics plants for HDPE/PP crates, drums, and housings with label removal and metal separation.

Applications of Plastic Granules

Packaging: blown/cast films, liners, shrink wraps, and laminates meeting MFI, haze, and dart impact targets.
Molding: injection and blow-molding parts for consumer goods, closures, crates, and containers.
Pipes and profiles: pressure/non-pressure pipes, corrugated ducts, and cable conduits with controlled MRS.
Textiles and straps: rPET chips for fibers and strapping with tensile and elongation stability.

Maintenance and Safety Tips

Inspect bearings, belts, knives, and filters daily; log vibration, temperatures, and pressures.
Maintain wash chemistry and replace contaminated water; clean tanks, pipes, and nozzles on schedule.
Calibrate sensors and load cells; verify heater zones, extruder pressure, and target MFI.
Train operators on lockout-tagout, hot surfaces, confined spaces, and emergency stop use.
Stock critical sparesâ€”heaters, thermocouples, seals, and screensâ€”stored dry with traceable codes.

FAQs â€“ Plastic Granule Plant

1. Which pelletizing method should I chooseâ€”die-face, water-ring, or strand? +

Die-face suits flexible films and higher throughputs; water-ring gives rounder pellets with compact layout; strand is simple and robust for rigid regrind. Selection depends on polymer, output, and downstream needs.

2. How do I size the extruder for my scrap mix? +

Match screw diameter and L/D to material bulk density, moisture, and target MFI. Moist or printed film benefits from two-stage degassing; rigid HDPE/PP may run well on single-stage with efficient filtration.

3. What utilities are typical for a 500â€“800 kg/hr plant? +

Three-phase power, process water for washing/cooling, and compressed air. Add water-recycling and effluent treatment to stabilize operations and reduce consumption during long shifts.

4. How can we ensure odor control and stable color? +

Use hot washing, effective drying, dual-vacuum vents, and fine filtration. Keep feedstock segregated, avoid burnt material, and track residence time to limit yellowing and odors.

5. What should be included in the after-sales package? +

Installation, commissioning, operator training, preventive maintenance plan, remote diagnostics, guaranteed spares, defined response times, and performance guarantees tied to throughput and pellet quality.
