The PVC/PP/PE/EVA/PLC/HDPE Plastic Extruder Granulator Air Cooling Pelletizer represents the pinnacle of modern recycling engineering. When operational, the machine emits a steady, rhythmic hum, a testament to the sheer power of its 315 kW motor driving the heavy-duty screw. Industrial facilities dealing with massive volumes of plastic waste will find this equipment transformative. Instead of accumulating space-consuming scraps, operators can feed irregular plastic pieces into the system, watching as the material is seamlessly melted, homogenized, and extruded into perfectly cylindrical, smooth-to-the-touch pellets.
The process begins with a precise feeding mechanism that channels raw waste into the heated barrel. Inside, the high-torque screw generates intense mechanical shear and thermal energy, breaking down the molecular memory of the plastics and transforming them into a flawless, viscous melt. As the molten plastic is forced through the precision-engineered die head, it forms continuous, uniform strands. These strands are rapidly cooled by a high-velocity air cooling system, instantly solidifying the material without introducing moisture. Finally, the rotating cutter shears the strands into immaculate, dense pellets that clink softly as they fall into the collection bin, ready for immediate integration into new manufacturing cycles.
To ensure your facility achieves optimal production targets, it is crucial to understand the technical capabilities of your processing equipment. The following specifications detail the precise engineering parameters of our advanced pelletizing system. Each metric is carefully calibrated to deliver maximum throughput while maintaining strict energy efficiency and operational stability. From the robust motor power to the precise screw speed, every component is designed to handle the most demanding industrial recycling tasks with unwavering reliability. We encourage facility managers and procurement engineers to review these exact specifications to ensure seamless integration into your current material recovery infrastructure.

It also reduces the overall equipment footprint by eliminating the need for large water tanks and centrifugal dryers.
Q: Can this machine handle heavily printed or contaminated plastic films?
A: Yes. The robust hydraulic screen changer effectively filters out solid impurities like paper labels or dirt. Additionally, the aggressive vacuum degassing system extracts the volatile inks and moisture associated with heavily printed films, ensuring a clean, solid, and odor-free pellet.
Q: What maintenance is required for the 315 kw main motor and gearbox?
A: The heavy-duty drive system requires routine lubrication of the thrust bearings and periodic oil changes in the reduction gearbox. The PLC system features built-in maintenance reminders based on operational hours, making it simple for your technicians to perform preventative upkeep before any mechanical wear occurs.
Q: Is it possible to adjust the pellet size during operation?
A: Absolutely. The rotary cutter is driven by an independent frequency inverter. By adjusting the cutting speed via the central touchscreen interface while maintaining a constant extrusion rate, operators can precisely calibrate the length and weight of the final pellets without stopping the machine.
