Machine to Separate Mix Plastic and Paper Fibers
The generation of paper-plastic mixtures is very common in daily life, especially in the use of paper cups, food packaging, and disposables. These packaging materials usually consist of paper fibers and plastic coatings, and this paper-plastic mixture not only takes up a lot of resources after disposal but also makes its recycling and reuse a big challenge due to the different nature of the two.
Currently, there are various options for paper-plastic separation technology and equipment, of which wet separation equipment (Hydro-Pulpers / Water Separation Systems) is one of the more common. The principle is to separate the lighter plastics from the heavier pulp through the floating and sinking properties of water. This method is particularly suitable for large quantities of mixed paper-plastic materials, where the paper fibers can be recycled into pulp during the separation process, which helps to reuse the paper. Wet separation is widely used in industrial recycling due to its ability to efficiently process larger quantities of waste.
In addition to wet separation, the Air Classifier / Air Separator also plays an important role in the separation of paper and plastic. This equipment separates materials of different densities and weights using airflow and is suitable for processing dry materials that have been pre-treated. The advantages of air flow separators are their simple structure, small footprint, and low energy consumption, which makes them ideal for large-scale industrial applications. In addition, the Vibratory Separator is widely used in the preliminary screening stage, where it removes plastic pieces or paper with large differences in volume to further optimize the separation.
For fine separation of tiny particles, the Electrostatic Separator is ideal. This equipment utilizes the difference in the electrically charged nature of plastic and paper materials to separate tiny plastic particles and paper powder through an electric field to achieve a high degree of separation accuracy. In some high-end applications, electrostatic separators can be effective in improving recovery rates, especially in those cases where the waste particles are fine and highly dispersed.
When choosing the right combination of separation equipment, several factors need to be considered, including the source of the mixture, the ratio of paper to plastic, the size of the processing volume, the cost of the equipment, and the energy consumption. In addition, environmental standards and subsequent reuse requirements are important considerations. In practice, reasonable equipment selection can improve separation efficiency, and reduce operating costs, to maximize the recovery and reuse of resources, if you are interested in machine to separate mix plastic and paper fibers or need it, please feel free to contact us for advice.
