Rigid plastic recycling granulating line
Name: Rigid plastic pelletizing line
Raw materials: Bottles, chemical drums, HDPE milk bottles, industrial pipes, WEEE Waste Electrical Equipment, ABS recycling, etc. rigid plastic materials.
Pelletizing way: water-ring cutting, cold strand cutting, under water cutting all available from POLYTEC to meet different conditions of materials.
Below use water-ring cutting as an example.
01— Project introduction
Rigid plastic waste is far from disposable. Through recycling and reprocessing, it is transformed into uniform, high-quality pellets that serve as raw material for new plastic containers, crates, pipes, bags, and pallets — turning waste into a valuable resource while reducing environmental impact.
02— Applicable materials
Daily plastic products, household appliances waste, auto parts(such as bumpers), electronic equipment cover, pipe, container, bottle, etc.

04— Advantages
  • Efficient Degassing — Effectively handles materials with printed surfaces and moderate moisture content, removing volatile contaminants during extrusion.
  • Continuous Filtration — Self-cleaning filtration system enables non-stop operation and prevents material leakage for uninterrupted production.
  • Hot Die-Face Pelletizing — Delivers stable, consistent production of uniform, high-quality plastic pellets.
  • User-Friendly & Energy-Saving Design — Ergonomic operation with optimized energy efficiency for lower running costs.

Plate type, piston type, and automatic self-cleaning type filter, you have different choice according to impurity contents in material and your habit. image.png Comparative advantages of large area net changer and plate type net changer:
1) larger filtration area 2-4 times, particle quality greatly improved
2) lower energy consumption :40-70 per cent lower energy consumption
3) the true meaning of no stop network without pressure fluctuations, water ring particles thickness more uniform.
4) higher durability and tightness
5) reduce filter mesh cost by 20% effectively
6) effectively prolong the time of network exchange, save manpower, reduce waste of raw materials

Water Ring Pelletizing Unit
Featuring an advanced European design, our water ring pelletizer delivers reliable, high-quality pellet formation.
Intelligent PLC Control Cutting speed is automatically regulated by the PLC in real time based on die-head pressure feedback, dynamically adjusting to maintain consistent cutting intervals — ensuring uniform pellet size and shape without manual intervention.
Key Advantages
  • Uniform pellet geometry for consistent downstream processing
  • Water ring cooling quenches pellets instantly, preventing agglomeration
  • Precision cutter head with durable alloy blades for long service life
  • Stable operation across PP, PE, PS, ABS, PET and other thermoplastics
The result is a steady stream of uniform, high-quality recycled pellets.
