Sink Float Plastic Separation

Our sink float plastic separation is a specially designed machine for PET bottle washing plants to clean and separate mixed plastics. Its main function is to effectively separate PET bottle flakes from labels or caps made of PP, PE, etc. to provide clean raw materials for subsequent processing.

Our sink float separation tank is designed to be advanced and easy to operate, with excellent separation efficiency and processing capacity. The equipment is made of high-quality materials with high durability to ensure long-term stable operation. In addition, we offer customized services to adjust and optimize the equipment according to customers’ specific needs.

Working Principle of Sink Float Plastic Separation

The machine uses water as the medium and utilizes the density difference for separation. When the mixed plastics enter the sinking and floating separation tank, the PET plastic will sink to the bottom of the tank because its density is greater than that of water, while PP, PE, and other materials will float on the surface of the water. By this way, the effective separation of mixed plastics is realized. The bottom of the machine is designed with a screw conveyor, which smoothly conveys the separated PET bottle flakes to the next process node and improves processing efficiency.

Configuration Recommendations For Sink Float Separation Tank

The number of sink float plastic separations is determined by the level of plastic contamination and the specific needs of the customer. Typically, this machine is installed after the automatic plastic bottle crusher to separate caps and residual labels from PET bottle flakes. If the quality of the final product is more important, one or two plastic float sink tanks can be considered to be installed in front of the plastic dewatering machine to further increase the separation efficiency.

Other PET Flakes Washing Machine

In addition to sink float plastic separations, our company also offers PET flakes washing machines such as hot washed PET flakes machines and friction washers. These machines work in conjunction with other PET bottle recycling machines to form a complete PET bottle washing line. We also provide customized solutions to flexibly configure the cleaning line according to the customer’s needs and production scale to achieve the best cleaning effect and production efficiency.
