Mechanische ontwateringstechnologie
Hogesnelheids centrifugaal ontwateringsmachine voor plastic folie
Mechanical bulk water removal for LDPE/LLDPE film, PP woven bags, and agricultural film — typically achieving ~3–5% moisture (material dependent) to stabilize extrusion and improve pellet quality.
Probleem versus oplossing
Stuit u op deze recyclingsuitdagingen?
Our centrifugal dewatering machine turns your biggest operational headaches into opportunities for higher profit and efficiency.
| Uitdaging | Traditionele aanpak | Centrifugaal Ontwateren |
|---|---|---|
| Energiekosten | Thermal dryers consume huge electricity to evaporate water | Centrifugal force removes 90%+ water mechanically — no heat needed |
| Pelletkwaliteit | Wet flakes cause gas bubbles, foaming, and brittle pellets | Stable <5% moisture ensures dense, smooth, high-value granules |
| Productiestilstand | Frequent clogs and jams from lightweight films | “Non-clog” rotor design ensures continuous operation |
| Restvocht | 20–30% vocht na traditionele droging | ~3–5% vochtgehalte (afhankelijk van het materiaal) |
Eenvoudig en effectief
Van Vochtige Korrels naar Droog Materiaal in 3 Stappen
Mechanical dewatering removes free water quickly and consistently, protecting your extruder from foaming, bubbles, and unstable melt.
Voeder nat materiaal
Wet film flakes from the washing line (friction washer or sink-float tank) are fed into the machine’s hopper.
Hoge snelheid ontwatering
The rotor spins at up to 1,500 RPM, generating immense G-force that ejects water through a perforated screen.
Verzamel droge vlokken
Dewatered flakes (~3–5% moisture) are discharged, ready for a hot-air stage, buffer silo, or pelletizing extruder.
Engineering Uitmuntendheid
Ontworpen voor maximale droogefficiëntie en bedrijfszekerheid.
Every component is designed for maximum drying efficiency, longevity, and minimal downtime.
Ultra-Hoge Snelheidsas
Heavy-duty rotor balanced for speeds up to 1,500 RPM generates extreme G-force, physically ejecting water far more effectively than low-speed tumbling. Optimized airflow design prevents clogging.
SUS304 roestvrij staal
Screen basket, housing, and all water contact points are fabricated from high-grade SUS304 stainless steel, making it impervious to corrosion.
“Non-Clog” Paddle Geometry
Aggressive, stepped paddle design tipped with wear-resistant alloy steel ensures continuous material flow, even with abrasive, sand-laden films.
Hoogwaardige lagers en eenvoudig onderhoud
Top-tier international bearings (SKF, NSK, FAG) in external water-cooled blocks extend service life. Segmented polygonal screen and pneumatic cover allow a single operator to swap screens in minutes.
Veelzijdig drogen
Ideaal voor Zachte Plastic Reinigingslijnen
Engineered for the rigorous demands of drying lightweight, high-surface-area plastics that standard dryers can’t handle.
LDPE / LLDPE-folie
Efficiently dry post-consumer and post-industrial films to prevent hydrolysis and foaming in the extruder.
PP Gesponnen Tassen
Process and dewater shredded PP woven and non-woven materials for consistent, high-quality granule production.
Landbouwmulchfolie
Our non-clog design handles sand-laden, abrasive films without blockages, ensuring continuous operation.
Algemene kunststofrecycling
Serves as the primary, high-throughput drying stage in any soft plastic washing and recycling facility.

Veelgestelde vragen
Een hoge-snelheidsfilmcentrifugaal ontwateringsmachine is speciaal ontworpen om gewassen plastic film te ontwateren met behulp van centrifugale kracht bij 800-1200 RPM. In tegenstelling tot standaard centrifuges die het moeilijk hebben met film, beschikt deze machine over een anti-wraps roterend wiel en een gespecialiseerde schermgeometrie die flexibel film kan verwerken zonder verstopping of materiaalverlies.
Speciale filmcentrifugaal ontwateringsmachines verminderen de vochtigheid van 30-40% tot 8-12%. Hoewel ze minder agressief zijn dan schroefperspersen (die een vochtigheidsreductie van 5-8% bereiken), bieden centrifugaalmachines een zachtere verwerking met minder materiaalverlies. Ze worden vaak gecombineerd met schroefpersen voor optimale vochtigheidsreductie.
They solve different problems. A centrifugal dewatering machine removes bulk water with high throughput (often ~3–5% moisture) and low energy compared with thermal evaporation. A squeezer is chosen when you also need densification and very low moisture (<1–2%), but it typically has higher capital and operating cost. Many film lines use centrifugal first, then a smaller squeezer or hot-air stage.
Material type (film vs. woven), flake size, feed stability, contamination (sand/dirt), water temperature, and upstream drainage all impact output moisture. We size the rotor/screen for your kg/h and your target dryness.
Most commonly after the final friction washer or sink-float tank. The discharge can feed a hot air pipe dryer, buffer silo, or the pelletizer/compactor depending on required moisture and layout constraints.
Yes — provided the upstream washing configuration is appropriate. For abrasive film, we recommend confirming wear protection options and selecting the correct screen perforation and wear parts for your contamination level.
