The Plastic Granulation Line is a highly efficient recycling solution designed to convert waste plastics into high-quality reusable pellets. It integrates feeding, extrusion, filtration, pelletizing, and cooling into one continuous automated system.
This line is suitable for processing various plastic materials such as PE, PP, HDPE, LDPE films, rigid plastics, and industrial plastic scraps. With stable performance and intelligent control, it ensures consistent output and excellent pellet quality.
The complete system includes key components such as belt conveyor, forced feeder, extruder, hydraulic screen changer, pelletizing unit, cooling system, and electrical control cabinet.
Working Principle
The Plastic Granulation Line operates through a continuous and automated process:
First, plastic waste is transported into the system via a belt conveyor.
Then, the material enters the forced feeder, ensuring stable and uniform feeding into the extruder.
Inside the extruder, the material is heated, melted, and plasticized through screw rotation and controlled temperature zones.
The molten plastic passes through a filtration system to remove impurities.
After filtration, the clean melt is extruded and cut into uniform pellets by the pelletizing system. Finally, the pellets are cooled, dried, and collected for reuse.
Working Principle
Details
Stable Feeding with Magnetic Separation
The belt conveyor with magnetic drum effectively removes metal impurities and ensures safe, continuous feeding into the system.
Forced Feeding System for High Efficiency
The screw-type forced feeder guarantees stable material input, especially suitable for irregular or bulky plastic scraps.
Advanced Degassing & Continuous Filtration
The extruder is equipped with an exhaust (degassing) section to remove moisture and volatile gases, improving pellet quality.The dual-station hydraulic screen changer enables non-stop filtration, ensuring cleaner melt and uninterrupted production.
Vertical Water Ring Pelletizing System
This system features uniform pellet size with Φ3×5mm customizable specifications, automatic blade pressure adjustment, and a splash‑free cooling design, ensuring smooth cutting, stable operation, and consistent production of high‑quality pellets.
Efficient Dewatering & Intelligent PLC Control
The vertical centrifugal dewatering machine efficiently removes residual moisture from pellets, while the PLC control cabinet delivers full automation control, overload and pressure protection, a temperature self-locking system, and alarm and automatic shutdown functions for safe and stable operation.
Pneumatic Conveying System + Cyclone Hopper
The pneumatic conveying system transports dried pellets efficiently to the cyclone hopper for storage.This system significantly enhances production efficiency and ensures clean, continuous pellet collection.
