Sink-Float Tank

Grinder-Injection-Series01

The float sink tank is a highly effective separation system designed to segregate plastic materials based on density. This pet float sink tank enables lightweight plastics such as LDPE, HDPE, and PP to float, while heavier materials like PET, PVC, and PC sink to the bottom, ensuring accurate and efficient separation in recycling processes.

Widely used as a pet bottle separation tank, it plays a crucial role in removing contaminants and improving the purity of recycled plastic flakes. The pet density separation tank enhances overall washing line efficiency by delivering consistent, high-quality output suitable for further processing such as drying and extrusion.

Built for durability and continuous operation, the float sink tank can be customized in size, structure, and processing capacity to meet specific recycling requirements. It is an ideal solution for plastic recycling plants seeking reliable performance, better material recovery, and precise separation results.

Details of Sink-Float Tank

Description

A Sink FLoat Tank is ideal for PE/PP/PET/PVC/ABS/HIPS/PC bottle recycling.

The PET Flakes will sink to the bottom while other material such as plastic wrapper and bottle cap flakes with float, Another application is mixed plastics streams.

Rigid PP/PE or film has a lower density making the plastics float while contaminatnt particles with sink to the bottom to be discarded.

  • Effective separation of different specific densities
  • Dosage unit for density adhjustment of the water with salt for example.
  • Compact design
