Efficient Separation with the Sink-Float Tank System

Efficient Separation with the Sink-Float Tank System-04


In the ever-evolving world of plastic recycling, the Sink-Float Tank System stands as a beacon of efficiency and effectiveness. This machine is a cornerstone in PET bottle recycling plants and other recycling applications, offering unparalleled separation of various plastics based on their densities. If you’re looking to streamline your recycling operations, this system is a must-have.

Working Principle

The Sink-Float Tank System utilises water as the medium for separation. As mixed plastic materials enter the tank, those with a density greater than water sink to the bottom, while those with a lower density float to the top. The system is equipped with specially designed rotating drums that help move the plastic pieces forward, ensuring a thorough separation process. Additives can also be introduced to enhance the separation efficiency.
