Sink float plastic separation is a piece of equipment commonly used for density separation in the plastics recycling process. This equipment effectively separates mixed plastic wastes by utilizing the difference in density of different materials in water. It is commonly used in PET washing lines to separate labels and caps from PET bottle flakes.
Features of Sink Float Plastic Separation
- Efficient Separation: The sink float separation tank utilizes density technology to effectively separate plastic bottle pieces from impurities, ensuring the purity of bottle pieces.
- Stainless Steel: The equipment is made of high-quality stainless steel with excellent corrosion resistance and durability.
- Flexible location: the plastic float sink tank is flexible in design and can be reasonably arranged according to the plant layout and production line requirements to maximize production efficiency.
- Various styles to choose from: Depending on the depth of the cleaning tank, there are various styles to choose from. For lighter PET bottle materials, it is recommended to choose a deeper separation tank to ensure better separation.
Working Principle of Washing Tank
The working principle of sink float plastic separation is based on density differences. The separation is achieved by creating different buoyancy forces in the water; PET flakes are usually denser than water, so PET flakes sink to the bottom, while lighter materials, such as labels and bottle caps, float to the surface.
PET bottle flakes that sink to the bottom of the trough are transferred to the next processing step by a screw conveyor at the bottom. Floaters are discharged through the rear discharge outlet for effective separation.
Number of Plastic Float Sink Tanks
For plastic bottle washing lines with an output of 500kg/h-1000kg/h, we recommend installing two or three sink float plastic separations, while for washing lines with an output of more than 1000kg/h, we recommend installing three or four.
The first separation tank is usually installed after the crusher and is mainly used to separate caps and labels from PET bottle flakes. The other washing tanks are installed after the PET flakes hot washing machines, which can not only separate the impurities again but also wash off part of the lye or cleaning powder, controlling the pH to less than 8 to ensure the cleaning effect.

Our sink float plastic separations are available in a variety of models, allowing customers to choose between deeper tanks or models equipped with paddle wheels, depending on the characteristics of the material or the needs of the customer. The deeper tanks are particularly suitable for lighter PET bottle flakes, while the paddle wheel design allows the material to be pushed forward during the cleaning process, improving processing efficiency.
