Hua County Daokou Big Dipper Electrostatic Separation Facility Factory is one of few enterprises recycling of renewable resources. The equipments used for the separation of scrap aluminum and plastic include: the separation equipments used for separating A***(Aluminium-plastic Composite Panel), the bottle cap of Wahaha, aluminum-plastic pipe, packaging of tablets and other leftover materials; copper-plastic separation equipments include: the separation equipments used for separating scrap wire, cable, waste printed circuit boards, copper clad laminate and leftover materials, circuit board drilling powder, copper plastic pipe etc. There are some other separation equipments used for separating conductors and non-conductors such as the high-tension electrostatic separation, the decarbonization of fly ash, separation of plastic and sands and separation of tea leaves and tea stems.
The energy-saving and environmentally friendly HL type electrostatic separator (alias: high-pressure electrostatic sorting machine) is developed through the cooperation of our factory and many domestic institutions and research units such as Peking University, China University of Mining and Electrostatic Association of China etc. on the basis of constantly absorbing domestic and foreign various separation techniques. Through years of practice and theoretical analysis, we obtain the best separation result and the impurity after separation is smaller than 1% and the best result can reach 99.9%. It belongs to complete physical separation after which, the property of various separated materials does not change, so it does not affect recycling. First the separator corona discharge generating device produces ionize in the surrounding air layer, and then metal and plastic (conductors and non-conductors) are separated from the crushed materials by the different permittivity.
The advantages of new device lie in that it needs not to use chemicals to dissolve wastes thus there¡¯s no pollution produced to environment. It is able to separate the plast
