DESCRIPTION
The Excellent Degassing and Filtering Pelletizing Line is an advanced solution engineered to tackle the challenges of recycling contaminated or moisture-laden plastic materials. Equipped with a precision-engineered degassing system and the innovative SCF self-cleaning filtration unit, this pelletizing line delivers outstanding melt purity and consistent granule output. It is particularly effective in handling printed film, post-consumer PE/PP waste, and industrial plastic scrap with up to 5% pollutant content.
Designed for continuous operation, this system reduces the risk of thermal degradation during processing and maintains a high-quality pellet output—essential for manufacturers focused on product stability and energy efficiency.

PRODUCTS DETAILS
Feeding & Automation
Plastic scraps such as films and filaments are fed via a belt conveyor, with an optional roll-hauling mechanism for continuous roll-fed input. The system uses ABB inverters to synchronize motor speed and automatically adjusts feeding based on real-time compactor fill levels. A metal detector is integrated into the conveyor, connected to the PLC to prevent machine damage from ferrous or non-ferrous contaminants.
Compactor with Air Exhausting
The compactor includes an air exhausting device, enabling friction-generated heat from rotor and stator knives to evaporate surface moisture and volatile contaminants. This pre-treatment reduces the load on downstream degassing components and improves extrusion quality while lowering energy consumption.
Dual Degassing System
Two strategically placed vacuum degassing zones remove residual micro-molecules and gases that can affect granule consistency. This setup is particularly important when dealing with printed films or hygroscopic materials prone to bubbling or discoloration during extrusion.
Barrel & Extended L/D Ratio
The extruder is built with an extended length-to-diameter (L/D) ratio, effectively functioning as a double-stage extruder within a single unit. This design increases melt residence time and stability, allowing for better plasticization and homogenization, even with low-MFI materials.
SCF Self-Cleaning Filtration
The non-stop piston-type filter features:
-
Double-station or four-station configuration
-
Large filtration area for extended service life
-
Continuous operation during screen change
-
Significant cost and labor savings
-
Quick-change modularity for minimal downtime
FAQ
Q1: What types of plastic can this pelletizing line process effectively?
A1: It handles PE, PP, PS, and ABS, particularly well with contaminated, printed, or high-moisture plastic films and scraps.
Q2: How does the SCF self-cleaning filtration system work?
A2: The SCF system allows continuous operation by automatically rotating screens without interrupting the extrusion process. This ensures melt consistency and reduces filter replacement frequency.
Q3: What is the function of the double vacuum degassing zones?
A3: They remove volatile gases, moisture, and ink residues from printed or foamed plastics. This results in pellets that are free from bubbles and discoloration.
Q4: Can the machine be customized for my specific material conditions?
A4: Yes, feeding systems, extruder L/D ratios, and screen configurations can all be tailored to your raw material composition and output requirements.
Q5: What are the advantages over a standard pelletizer without degassing and dual filtration?
A5: You’ll achieve higher pellet quality, reduced downtime, and the ability to process more challenging materials with consistent melt pressure and purity.
