Questions
Product FAQ
What materials can the sink-float separation tank process?
It can be used for PET flake separation and for washing compatible PP/PE rigid and flexible plastic materials, depending on the equipment configuration.
How does it separate PET flakes from PP/PE caps?
PET generally sinks in water, while common PP and PE caps float. The tank separates these materials according to their density differences.
Can it remove all contaminants from PET flakes?
It mainly separates materials based on density. Adhesives, certain labels, metals, and contaminants with similar densities may require additional washing or sorting equipment.
Can the equipment be integrated into an existing recycling line?
The tank dimensions, water supply, discharge arrangements, and conveying system can be configured according to your existing line.
How can I get a quotation?
Please provide your material type, expected processing capacity, and existing process flow so we can recommend a suitable solution.
