The Double Stage Water Ring Pelletizer with Compactor is a complete film-to-pellet recycling system engineered for PE and PP film waste. It transforms post-consumer agricultural film, industrial stretch wrap, and packaging film scrap into high-density, uniform recycled pellets suitable for reprocessing into film, pipe, and injection-molded products. Core differentiators include an integrated compactor that eliminates pre-crushing, a dual-stage venting system that delivers superior melt purity, and water-ring die-face cutting that ensures consistent pellet geometry - all managed through PLC automation for 24/7 continuous operation.
The Double Stage Water Ring Pelletizer Machine is a closed-loop film recycling solution designed to convert light, bulky PE/PP film waste into dense, free-flowing recycled pellets ready for commercial reuse.
Unlike single-stage pelletizer that produce irregular flakes requiring further processing, this integrated two stage plastic pelletizing line combines three critical functions in one continuous line: densification, extrusion and pelletizing. The result is a streamlined workflow that reduces labor, floor space, and intermediate handling.
Applications & Feedstock
This water ring pelletizing system is engineered for the following film waste streams:
- Post-consumer agricultural mulch film
- Post-industrial stretch wrap and silage film
- LDPE/LLDPE packaging film from sorting facilities
- PP woven bags and raffia
- Mixed film scrap with up to 20% printed or laminated content
The resulting recycled pellets (3–4 mm spherical) exhibit consistent melt flow index (MFI) and are directly usable in:
- Blown film extrusion (for non-food packaging)
- Pipe and profile extrusion
- Injection molding applications
- Compounding and masterbatch production.
How It Works - Three Mechanisms for Superior Pellet Quality
This water ring pelletizing line solves the fundamental challenges of film recycling through three engineered mechanisms:
1, Integrated cutting compacting & feeding
The heavy-duty compactor unit pre-cuts, densifies and force-feeds loose film material directly into the extruder barrel. It eliminates the need for separate shredding or agglomeration equipment, prevents bridging and surging, and ensures a consistent material feed rate even with low-bulk-density films (down to 50–80 kg/m³).
2, Dual-stage extrusion with advanced venting and perfect filtration
The unique double-stage configuration features two independently controlled extrusion stages separated by a large venting zone. This design actively removes moisture, volatiles, and residual contaminants - a critical advantage when processing printed, washed, or mixed film scrap. The degassing efficiency significantly outperforms single-stage systems, resulting in melt with fewer voids and higher tensile properties in the final pellets.
Hydraulic screen changers are installed on each of the two extruders, providing effective contamination removal from the film feed and guaranteeing premium pellet purity.
3, Water-Ring die-face pelletizing
At the extrusion die, the molten strands are cut directly at the die face by rotating blades and immediately quenched in a water-ring chamber. This rapid cooling prevents pellet agglomeration, maintains precise dimensional tolerance (±0.5 mm), and produces high-bulk
-density pellets (550–650 kg/m³) with excellent flowability for downstream pneumatic conveying and blending operations.

Why This System - An Economical and Environmental Value Proposition
From an operational perspective, the Double Stage Water Ring Pelletizer with Compactor reduces processing costs by eliminating pre-crushing and minimizing energy consumption. Its PLC-controlled automation allows single-operator supervision, reducing labor overhead.
From an environmental standpoint, this system enables closed-loop film recycling, diverting post-consumer and industrial film waste from landfills or incineration. The high-purity pellets produced can substitute virgin resin in many applications, delivering measurable carbon footprint reduction. For film processors and recyclers alike, this represents a sustainable, commercially viable approach to plastic waste valorization.
Engineered for Reliability - Built for 24/7 Industrial Operation
All contact parts are constructed from wear-resistant steel with anti-corrosion coating. The machine frame features vibration-damping mounts for stable high-speed operation. The modular design allows easy integration with upstream washing lines and downstream pellet storage silos. Backed by a comprehensive warranty and global technical support network, this water-ring pelletizing system is built for the demanding conditions of continuous industrial recycling facilities.
