Excellent Degassing and Filtering Pelletizing Line
The Excellent Degassing and Filtering Pelletizing Line is a high-performance recycling system developed for efficient re-granulation of contaminated plastic waste. It is designed to deliver strong degassing and advanced filtration, helping prevent overheating and material degradation during processing. This results in stable output and consistently high-quality plastic pellets suitable for reuse in production.
At the core of the system is a newly developed standard recycling granulation platform combined with the SCF self-cleaning filtration system. This configuration allows continuous removal of impurities from the melt flow, effectively eliminating up to 5 percent of pollutants without interrupting production. By maintaining a clean and stable melt, the system improves pellet quality and reduces downtime caused by screen changes or clogging.
The Excellent Degassing and Filtering Pelletizing Line is especially suited for highly polluted and printed plastic materials that are difficult to process using conventional pelletizing systems. Its balanced processing design supports smooth plasticization, reliable degassing, and effective filtration in one continuous line. This makes it a practical and dependable solution for recycling operations focused on material recovery, quality improvement, and long-term operational stability.

FEEDING
Films, filaments, and raffia are conveyed to the compactor via a belt conveyor as standard, while roll stock can be handled with an optional roll-haul-off unit.
Both drives work with ABB inverters, automatically matching feed speed to the compactor fill level for steady, jam-free throughput.
A belt-mounted metal detector integrates with the control system to warn and stop the line upon detecting metal, protecting downstream components.
COMPACTOR WITH AIR EXHAUST
Continuous cutting and friction in the compactor generate gentle process heat, lifting surface moisture and dust from the feedstock.
The integrated air-exhaust unit removes these volatiles without extra energy input, pre-dries the material before granulation, and reduces load on downstream degassing—boosting efficiency and final pellet quality.
SLIDING GATE WITH SERVO MOTOR
A servo-driven sliding gate controls residence time to suit both hard and soft materials.
Only clean, pre-dried feed proceeds to the barrel; off-spec material is retained for additional conditioning.
PLC logic precisely meters forced feeding to maintain target throughput with consistent results.
PROTECTION SYSTEM
– Electrical safety interlocks guard all access points and rotating parts, prioritizing operator safety.
– Tight temperature control and optimized plasticization deliver uniform, high-quality pellets.
– Smart logistics across modules ensure each polymer type receives the right pre-heating and compacting—avoiding overheating and degradation.
REMOTE MONITORING & INFORMATION TRANSMISSION
Built-in program control and Bluetooth connectivity enable remote status checks, parameter adjustment, and performance data transfer—supporting proactive maintenance and faster decision-making.
ROTATORY BLADES OF COMPACTOR
High-speed rotary and fixed blades reduce material to uniform flakes while frictional heat pre-shrinks and pre-heats them—stabilizing feed density and improving extrusion efficiency.
INTELLIGENT CONTROL
Intelligent Start: One-button startup synchronizes all modules.
Intelligent Stop: One-button stop brings the line down safely and quickly.
Emergency Stop: Dedicated E-stop circuits protect operators and equipment in unexpected scenarios.
SINGLE SCREW EXTRUDER
The precision single-screw extruder gently plasticizes and homogenizes the melt.
A bi-metallic barrel/screw package delivers outstanding wear and corrosion resistance for long, stable service life.
BARREL
An extended L/D design enables single-stage processing with double-stage performance.
Positioned after a mid-line double-piston screen, an optional final filter further elevates pellet purity and stability.
DOUBLE VACUUM DEGASSING ZONES
Dual degassing ports remove moisture, micro-molecules, and volatile contaminants—ideal for heavily printed or mixed feeds—resulting in cleaner melt and higher-grade granules.
LIQUID OUTLET
Designed to improve melt filtration and throughput, the line can be configured with multiple single-screw extruders feeding a second-stage extruder—scaling capacity and refining quality.
NON-STOP PISTON TYPE FILTER
Choose single/double-station or continuous four-station piston screen changers for high filtration capacity.
Large filter areas extend screen life, and quick, on-the-fly changes keep production continuous—reducing costs and downtime.
PLATE TYPE FILTER
A continuous dual-plate layout keeps one filter active during screen changes.
A ring heater ensures uniform, stable temperature for consistent filtration performance.
SELF-CLEAN FILTER
The SCF system enables continuous extrusion with highly contaminated streams, removing up to ~5% impurities.
It reliably separates paper, wood, aluminum, unmelted plastic, rubber, and more—keeping lines running and pellets clean.
WATER RING PELLETIZING SYSTEM
A self-adjusting head keeps blade pressure optimal for consistent granulate quality and uptime.
Blade RPM adapts to melt pressure, and quick blade changes require no re-tuning—saving valuable maintenance time.
UNDER-WATER PELLETIZING SYSTEM
Highly automated for high-MFI resins and large capacities, this package includes pelletizer, valve, piping, dewatering vibration screen, and silo—delivering uniform pellets at scale.
VIBRATION DRY
A high-efficiency dewatering vibration sieve pairs with horizontal centrifugal drying to cut energy use and deliver drier pellets.
Screw-assembled sieves (no welds) speed future changeovers and reduce maintenance effort.
PLASTIC PARTICLES
The line produces high-quality recycled pellets suitable for reuse in premium plastic applications—closing the loop and maximizing material value.
PACKING SYSTEM
Final pellets are efficiently dried with a shaker and horizontal centrifuge before storage.
Online capacity monitoring and precise weighing ensure accurate inventory and shipment readiness.
