“…Electrostatic separation is efficient method to separate not only plastics or metals (e.g. cables and electric wires, electronic equipment, household appliances, cars), but also organic materials such as wheat, grain, flour, roughage, protein, oilseeds, legumes and has been used on a large scale for over 60 years [13][14][15][16][17][18][19][20][21]. Currently, scientists in many research centers are working intensively on the development of modern electrostatic separation systems -separators -aiming their efforts to increase the effectiveness of the separation process.…”

“…accumulation of electrostatic charge on its surface as a result of its friction with another material is the most common method to charge the plastic particles. [18][19][20]26]. Despite many experimental and theoretical research of this process, due to its complexity in the atom scale, the phenomena of triboelectrization of plastics is still not fully recognized.…”

Plastics recycling has become a key industry in developed countries, to reduce ecological damage and save non-renewable resources. This paper discusses the concept and the design of electrostatic separator as a test bench for the separation of different plastics in recycling applications. In the automotive recycling process, all these waste materials must be processed further for re-entering the cycle or thermal utilization. The following application presents the possibility of research and technological tests by changing several parameters, such as a position of the electrodes, control of the polarity and voltage, variable speed of feeder and drum, and also tribo-electrification parameters (time, intensity). The impact of process parameters on the efficiency of the plastic separation can be analyzed by the developed a specialized computer vision system. The preliminary results of conducted tests showed that separation is dependent on many variations of parameters. The results of this study indicate that the proposed innovative design of the research stand ensures the high research potential of the proposed equipment.

Many researchers in the developed countries have been intensively seeking effective methods of plastic recycling over the past years. Those techniques are necessary to protect our natural environment and save non-renewable resources. This paper presents the concept of an electrostatic separator designed as a test bench dedicated to the separation of mixed plastic waste from the automotive industry. According to the current policy of the European Union on the recycling process of the automotive industry, all these waste materials must be recycled further for re-entering into the life cycle (according to the circular economy). In this paper, the proposed concept and design of the test bench were offered the feasibility to conduct research and technological tests of the electrostatic separation process of mixed plastics. The designed test bench facilitated assessing the impact of positions of high-voltage electrodes, the value and polarity of the high voltage, the variable speed of feeders and drums, and also triboelectrification parameters (like time and intensity) on the process, among others. A specialized computer vision system has been proposed and developed to enable quick and reliable evaluation of the impact of process parameters on the efficiency of electrostatic separation. The preliminary results of the conducted tests indicated that the proposed innovative design of the research stand ensures high research potential, thanks to the high accuracy of mixed plastics in a short time. The results showed the significant impact of the corona electrode position and the value of the applied voltage on the separation process effectiveness. It can be concluded that the results confirmed the ability to determine optimally the values of the studied parameters, in terms of plastic separation effectiveness. This study showed that this concept of an electrostatic separator designed as a test bench dedicated for separation of mixed plastic waste can be widely applied in the recycling plastic industry.

Separacja proszków węglowych o dużym stopniu rozproszenia za pomocą metody tryboelektrycznej Streszczenie. W artykule zostały przeanalizowane warunki rozdzielenia materiałów węglowych za pomocą metody tryboelektrycznej. Została opracowana konstrukcja i wykonane urządzenie powietrznej separacji tryboelektrycznej z oddzielaczem bębnowym. W drodze eksperymentu ustalono, że zastosowanie wibracji podczas podawania proszku do bębna oraz obróbka cieplna proszków istotnie wpływa na wartość tryboładunków. W celu uzyskania dobrego wyniku rozdzielenia materiałów węglowych konieczne jest osuszenie. Materiał osusza się w temperaturze 100-120 о С. Otrzymane za pomocą separacji frakcje węglowe zastosowano do budowy superkondensatorów. Określono pojemność właściwą. Ustalono, że największą pojemność właściwą posiada materiał zawierający cząstki o wymiarach 1-10 µm.
