Centrifugal Dewatering Machine for Rigid Plastic Flakes
The essential first step in your drying process. Our robust centrifugal dryer uses high-speed mechanical force to remove the bulk of water from PET, HDPE, and PP flakes, dramatically saving energy and improving throughput.
Your Competitive Advantage in Plastic Recycling
Achieve lower moisture content, higher quality output, and significant operational savings. Our dewatering machine is the workhorse that powers a more profitable washing line.
Exceptional Drying Performance
Drastically reduces moisture levels in rigid flakes down to 2-3%. This is crucial for preparing material for the final drying stage and producing high-quality pellets in subsequent extrusion.
Massive Energy Savings
By mechanically removing most of the water, our machine takes the heavy load off your energy-intensive thermal dryers, significantly cutting your plant's overall energy consumption and operational costs.
Dual-Action Final Cleaning
The high-speed friction at nearly 1,400 RPM not only expels water but also provides a final, intensive scrubbing action, helping to remove fine paper labels and other residues to further purify your plastic flakes.
The Principle of Centrifugal Force
Material Feed
Wet, washed plastic flakes are fed into the machine's vertical inlet.
High-Speed Rotation
A central shaft with durable paddles spins at high velocity (up to 1400 RPM).
Water Expulsion
Centrifugal force throws flakes against a mesh screen, forcing water out for collection.
Convey & Discharge
The spinning paddles propel the drier flakes along the screen towards the outlet.

Frequently Asked Questions
What types of plastic is this dewatering machine best for?
This machine is specifically designed and optimized for rigid plastic flakes, such as crushed PET from bottles, and rigid PP/PE flakes from drums, pipes, or crates. It is not suitable for soft plastics like PE films, which require a squeezer-dryer.
What is the typical moisture level after using this machine?
For rigid plastic flakes, you can expect our centrifugal dewatering machine to reduce the moisture content to an impressively low 2-3%. This provides an ideal foundation for the final, less energy-intensive thermal drying stage.
How is the mesh screen maintained?
We've designed the machine for easy access. The screen housing can be opened quickly, allowing operators to clean, inspect, or replace the screen with minimal downtime, keeping your production line running efficiently.
