Sink Float Separation Tank for PET Bottle Recycling
The essential heart of any PET washing line. This sink float separation tank uses water density to perfectly separate valuable PET flakes from lighter PP/PE bottle caps and labels. Simultaneously wash and purify your material stream to achieve superior purity, higher yields, and greater profitability.
描述
The Ultimate Sink Float Tank for PET Bottle Recycling
Expertly separate valuable PET flakes from lighter PP/PE bottle caps and labels. Our tank uses advanced density separation to simultaneously wash and purify your material stream, guaranteeing higher quality output for your recycling line.
Key Advantages for Your PET Recycling Line
Isolate Pure PET Flakes
Achieve exceptional purity by effectively separating sinking PET flakes from floating PP/PE contaminants, boosting the value of your final product.
Built for Durability
The interior, constructed with Type 304 stainless steel, withstands the demanding environment of a 24/7 washing line, ensuring longevity and reliability.
Wash & Separate
The extended tank design and rotating drums provide ample soaking time, not only separating materials but also washing away dirt and grime.
How We Isolate PET Flakes from Caps & Labels
Crushed Bottle Mix
SEPARATION IN WATER
Floating: PP/PE (Caps/Labels)
Sinking: PET (Bottle Flakes)
Pure PET Flakes
Because PET plastic (density ~1.38 g/cm³) is denser than water, it sinks to the bottom and is removed by a screw conveyor. Lighter materials like PP/PE caps and labels float to the surface and are discharged separately, leaving you with a clean, high-value PET stream.
Applications & Technical Specifications
Primary Application
PET Bottle Recycling
The indispensable heart of any PET washing line. Granulating whole bottles results in a mixed stream; this tank provides the crucial separation step that defines the purity and profitability of your entire operation.
Other Applications
Also effective for separating heavy contaminants from plastic films and processing various co-mingled rigid plastics.

Frequently Asked Questions
What is the typical separation purity I can expect for PET flakes?
Our sink float tank is engineered to achieve a separation purity of over 99% for PET flakes from PP/PE contaminants under optimal conditions. The final purity can be influenced by the initial contamination level and the condition of the input material.
How does the tank handle water consumption? Is the water recyclable?
Yes, the water is highly recyclable. The system is designed to operate as a closed loop. Water is continuously circulated within the washing line. You only need to replenish the water lost due to evaporation and discharge with the contaminants, making it very water-efficient.
What happens if other dense plastics like PVC are mixed in with the PET?
This is an excellent question. Since PVC is also denser than water, it will sink along with the PET flakes. Our sink float tank is designed specifically to separate materials based on density relative to water. For removing PVC contamination from PET, we recommend incorporating additional technologies like an optical sorter into your recycling line before or after the washing process.
What kind of maintenance is required for the tank?
The tank is designed for low maintenance. Regular tasks include checking and cleaning the filters, inspecting the screw conveyors and rotating drums for any blockages, and periodically draining the tank to remove fine sediment buildup. The robust 304 stainless steel construction minimizes corrosion-related maintenance.
