Part of a Complete Plastic Washing & Pelletizing Line
This machine is one stage of a full recycling line. A typical wet line runs in this sequence, and the equipment below covers each stage:
- Friction Screw Washer — scrubs off oil, labels, and surface dirt before separation.
- Sink-Float Separation Tank — separates plastics by density, floating light polyolefins off heavier resins.
- Centrifugal Dryer — spins off free surface water mechanically after washing (this machine).
- Thermal Dryer — hot-air drying to below 1% moisture before pelletizing.
- Rigid PP/HDPE Flake Pelletizer — pelletizes clean rigid HDPE and PP flake into uniform pellets.
- Single-Screw Pelletizing Line — water-ring or strand single-screw pelletizing at production throughput.

Frequently Asked Questions
This machine serves as the crucial first step in the drying process. It uses centrifugal force to mechanically remove the majority of surface water from plastic flakes, which is a very energy-efficient method before the final thermal drying stage.
A dewatering machine can typically reduce the moisture content of washed plastic flakes down to approximately 20-30%. This prepares the material perfectly for a thermal dryer to achieve final moisture levels of under 3%.
Yes, our innovative design allows it to also function as a friction washer. It uses cold water to simultaneously cool and further scrub the plastic flakes, helping to remove any remaining fine contaminants.
It is designed for washed plastic flakes such as PET, HDPE, PP and rigid mixed flakes, and it can also be used for washed film flakes. The best configuration depends on flake size, density and incoming moisture level.
Selection depends on your washing line throughput, incoming moisture and flake characteristics. Choose a model whose capacity matches your line and leaves headroom to avoid bottlenecks; we can recommend HXJ400/550/750 based on your material and target output.
Part of a Complete Drying System
As a first-stage dewatering solution, the centrifugal dryer is an essential part of any complete plastic drying system. For final moisture targets below 3%, follow it with a thermal dryer to achieve bone-dry results required for premium pelletizing. For film materials, consider a film squeezer dryer which handles flexible plastics more effectively.
