What is a Styrofoam Wind Sifter?
A Styrofoam Wind Sifter, also known as a Foam Air Separator or EPS Separator, is used to separate low-density materials such as EPS foam, Styrofoam, plastic film, and other lightweight impurities from mixed waste. The machine uses adjustable airflow to separate lightweight and heavy materials based on density and airflow resistance differences. The FMX series is mainly used in EPS recycling, C&D waste recycling, and waste sorting plants, and is typically installed after shredders, crushers, or screening equipment.
Applicable Materials
FMX Styrofoam Wind Sifter is designed for separating lightweight materials from mixed waste, including EPS foam, Styrofoam, EPP and PU foam, plastic film, PET flakes, PE/PP plastics, paper, wood chips, textile pieces, rubber particles, and other low-density impurities. It is commonly used in EPS recycling, C&D waste recycling, MSW sorting, industrial waste recycling, and waste sorting plants.
During operation, the adjustable airflow carries lightweight materials such as foam, film, and paper into the light fraction outlet, while heavier materials such as concrete, stones, glass, and metals move to the heavy fraction discharge. Before separation, these materials are mixed together and reduce the quality of recycled products. After separation, lightweight materials and heavy fractions are collected separately for further recycling or processing.
Material Before & After Comparison
EPS foam separator uses aerodynamic separation to remove lightweight materials from mixed waste streams. By controlling airflow, it separates foam, plastics, and other light fractions from heavy materials such as concrete, bricks, and stones, improving the quality of recovered materials.
Working principle
FMX Styrofoam Wind Sifter uses aerodynamic separation to separate lightweight materials from heavy fractions. By controlling airflow, the system separates materials based on density and air resistance differences. The separation process includes material feeding, airflow generation, lightweight material separation, and final material collection.
Material Feeding: Mixed materials enter the separation chamber evenly through conveyors after shredding and screening for efficient airflow separation.
Controlled Airflow Generation: The fan creates adjustable airflow inside the separation chamber, with air volume and speed adjusted according to material characteristics.
Foam Material Separation: Lightweight materials such as EPS foam and plastic film are lifted and carried by airflow, while heavy materials such as concrete, bricks, and stones fall by gravity.
Separated Material Collection: Separated lightweight materials are discharged through the light fraction outlet, while heavy materials are collected from the bottom outlet for further recycling.
