This demonstration shows a high-speed centrifugal dryer removing surface water from recycled plastics, including PP film and LDPE. Watch how the material moves through the dryer and leaves the machine. This is the mechanical drying step that can come before hot-air drying or another stage with a tighter moisture requirement.
Separating surface water by spinning
The centrifugal dryer uses a fast rotor to press wet plastic against a screen, allowing water to pass through while the plastic is discharged. The source demonstration describes applications that include LDPE and PP film alongside other recycled plastics. It focuses on mechanical water removal.
When you evaluate this stage for film, check how the wet material enters and what condition it needs to reach at discharge. If the next step has a tighter moisture requirement, use the outlet sample to decide whether the line also needs thermal drying or squeezing.
