PVC/PET/PC Sink-Float Separation Tank for Heavy Plastics
Engineered to separate heavy plastics (PVC, PET, PC, PS) from floatables (PP/PE) with an integrated process that combines pre-rinse, density separation, and silt discharge. The modular tank connects seamlessly to washing lines and consistently outputs a high-purity heavy fraction.
Ideal for recyclers building or upgrading washing lines, this unit improves separation purity and stabilizes throughput without compromising energy efficiency or serviceability.
How It Works
Shredded feed enters the tank; process water disperses surface soils for a cleaner, more uniform flow.
Floatables (PP/PE) rise; heavy plastics (PVC/PET/PC) sink, creating a clear stratification for accurate split.
A bottom screw/scraper gently abrades the heavy fraction and guides silt to discharge, reducing carryover.
The floating layer exits via an overflow weir to dewatering or further washing; heavy fraction discharges from the bottom outlet.
Connects to settling/filtration for a closed loop; bleed and make-up water are tuned to contamination load.
Key Benefits
Optimized flow field and working volume lower cross-contamination and raise downstream product value.
Series/parallel combinations match capacity and layout, enabling easy upgrades and fast delivery.
Easy access to critical areas; standardized wear parts shorten downtime and control service cost.
Closed-loop water and adjustable overflow reduce consumption; efficient drives lower kWh per ton.
Reinforced tank, anti-corrosion details, and leakage control ensure long-term stable operation.
Handles heavy fractions (PVC/PET/PC) and floatables (PP/PE); fits diverse washing processes.
Pains We Solve
Fix: Tuned tank proportions and flow guides maintain a steady flow field, reducing short-circuiting and vortices.
Fix: Closed-loop water and adjustable overflow match system load to cut unit consumption and cost.
Fix: Bottom-mounted drives and quick-change wear parts simplify inspection and reduce downtime.
Fix: Bottom screw plus guided silt discharge minimize fines carryover into the heavy fraction.
Fix: Modular length sections and supports allow easy insertion or replacement in existing lines.
Fix: Standardized manufacturing and factory testing ensure consistent performance and traceability.
