The sink float separation tank plays a vital role in the PET bottle washing and recycling process. As the key equipment for separating impurities and improving recycling efficiency, it can efficiently separate PP or PVC labels from PET bottle flakes, thus ensuring the purity of the recycled material.

What is a sink float tank and its function

The sink float separation tank is a kind of equipment that uses the difference in material density to separate impurities, which is especially important in PET bottle cleaning and recycling.

It makes the lighter impurities (such as PP bottle caps, and PVC labels) float on the water surface through the floating and sinking characteristics of the water, while the heavier PET bottle flakes sink to the bottom of the tank, to efficiently separate the impurities, improve the purity of bottle flakes, and provide a guarantee for the subsequent processing.

How Does a Sink Float Separation Tank work?

Sink float plastic separations work based on the principle of density difference and buoyancy. When the mixture enters the separation tank, the lower-density PP bottle caps or PVC labels float to the surface, while the higher-density PET bottle flakes sink to the bottom of the tank.

Using the push of the water current and the design of the equipment, the impurities floating on the surface are discharged and the PET bottle flakes that sink to the bottom are transferred to the next process through a conveyor.

Improvement of PET Bottle Flakes Quality

PET bottle recycling process contains a large number of labels, caps, and other impurities, without the sink float separation tank, the impurities will affect the quality of bottle flakes cleaning and the quality of recycled materials. The plastic float sink tank removes impurities during the initial cleaning process, providing cleaner raw material and ensuring that the quality of PET bottle flakes is suitable for subsequent processing.

Characteristics of Our Plastic Float Sink Tank

As a professional manufacturer of plastic recycling equipment, our sink float plastic separations have the following features in design and performance:

• Optimized design: the machine is wider and taller, effectively preventing excessive bottle flakes from being taken out when discharging impurities.
• High-efficiency Separation: Accurately separates PP, PVC, and other impurities to improve the purity of PET bottle flakes.
• Sturdy and durable: adopting high quality anti-corrosion material, suitable for long-term operation in high humidity environment.
• Flexible customisation: adjust the size and design according to customer’s needs, suitable for different production lines.
• Convenient operation: simple structure, low maintenance cost and stable operation.

结论

The sink float separation tank plays an irreplaceable role in the PET bottle cleaning and recycling process. It improves the recycling quality of PET bottle flakes by efficiently separating impurities while optimizing production efficiency. Our sink float tanks provide a reliable solution for our customers thanks to their high separation efficiency, durability, and flexibility.
