Plastic Pelletizing Machines & Pelletizers for Recycling
Convert washed flakes, PE/PP film, woven bags, BOPP, PET flakes, EPS foam, EVA foam, meltblown nonwovens, and rigid regrind into uniform recycled pellets. Energycle supplies single-screw, twin-screw, cutter-compactor, water-ring, strand, and material-specific pelletizing lines for industrial recycling plants.
Turn Washed Plastic Waste into Higher-Value Pellets
Pelletizing plastic — turning washed scrap into uniform, higher-value pellets — improves bulk density, handling, storage, feeding stability, and resale value. The right line configuration depends on the polymer, material form, moisture, contamination, melt flow, and final application.
Stable Recycled Pellet Quality
Filtration, degassing, melt pressure control, and pellet cutting help produce uniform recycled pellets with consistent downstream processability.
Haute densité volumique
Pellets are easier to convey, store, package, and sell than loose film, low-density regrind, or washed flakes with inconsistent shape.
Material-Specific Screw Design
Screw structure, L/D ratio, venting, temperature zones, and feeding method are selected for film, rigid flakes, PET, EPS, EVA, BOPP, or compounding tasks.
Dégazage et filtration
Single, double, or multi-stage degassing and screen changers remove moisture, volatiles, ink residue, gels, and solid contaminants before pelletizing.
Turnkey Line Integration
Pelletizers can connect with shredders, washing lines, dryers, squeezers, conveyors, silos, and packing systems for continuous recycling production.
Lower Operator Burden
Automatic feeding, melt pressure monitoring, temperature control, pellet drying, and pneumatic conveying reduce manual handling and stabilize output.
Comment fonctionne une ligne de granulation de plastique
A pelletizing line converts clean plastic scrap into melt, filters and degasses the melt, then cuts it into uniform pellets for reuse in extrusion, injection molding, compounding, or film production.
Feed & Pre-Densify
Film, foam, flakes, or regrind are fed by conveyor, force feeder, cutter-compactor, agglomerator, or side feeder.
Melt & Degas
The extruder melts plastic and removes trapped moisture, air, ink volatiles, and low molecular contaminants through venting zones.
Filter & Stabilize
Screen changers and melt pumps help remove solids and stabilize pressure before pellet cutting.
Cut, Dry & Pack
Water-ring, strand, or underwater cutting forms pellets that are dewatered, dried, cooled, and conveyed to storage.
Feed & Pre-Densify
Prepare low-density or irregular scrap for stable extrusion feeding.
Melt & Degas
Melt plastic while removing moisture, air, and volatile residues.
Filter & Stabilize
Remove solid contamination and stabilize melt pressure.
Cut, Dry & Pack
Cut uniform pellets and prepare them for storage or sale.

Connect Pelletizing with Washing, Drying, and Material Preparation
Pellet quality starts before the extruder. If the material is dirty, wet, bulky, or mixed, upstream preparation is just as important as the pelletizer itself.

Plastic Pelletizer Questions
A few practical questions to clarify before choosing a pelletizing line.
What is the difference between a pelletizer and an extruder?
The extruder melts, mixes, degasses, and pressurizes the plastic. The pelletizer cuts the molten polymer into pellets. In recycling, both are usually integrated with filtration, cooling, drying, and conveying as one pelletizing line.
Which pelletizer is best for PP/PE film?
For low-density film, a cutter-compactor or agglomerator feeding system with a single-screw extruder and water-ring pelletizing is commonly recommended. The exact choice depends on moisture, print level, contamination, and capacity.
Do plastic flakes need to be washed before pelletizing?
If flakes contain dirt, labels, glue, oil, paper, sand, metal, or mixed polymers, washing and drying are strongly recommended before pelletizing. Clean post-industrial scrap may go directly to size reduction and extrusion.
When should I choose twin-screw extrusion?
Twin-screw extrusion is useful when you need strong mixing, additive dosing, filler dispersion, polymer modification, devolatilization, or compounded recycled pellets with controlled formulation.
What information is needed for a quotation?
Please provide material type, photos or videos, moisture level, contamination, bulk density, target output capacity, desired pellet application, power supply, and whether washing or drying equipment is already installed.
