Application of High Voltage Power Supply in Electrostatic Separation

Electrostatic separation is a method to achieve separation by utilizing the difference in electrical properties of each component in a solid material in a high-voltage electric field. The electrification method of the material in electrostatic sorting is direct conduction electrification. The material is in direct contact with the conductive electrode. The material with good conductivity will get the same charge as the electrode and be repelled. The material with poor conductivity or non-conductor will be polarized when it contacts the charged roller, and the opposite bound charge will be generated at the end close to the roller. Attracted by the roller, so as to realize the separation of different electrical materials.

The main components of the electrostatic separation equipment are a negatively charged insulating roller and a set of positive electrodes close to the roller and the feeder. When the material is close to the surface of the roller, due to the induction of the high-voltage electric field, the surface of the conductor particles is polarized and charged positively. Electric charge, attracted by the aggregated electric field of the drum. After contact, it is negatively charged due to conduction, and is repelled by the roller under the action of Coulomb force, and falls away from the roller. Because the insulator does not produce the above effects, it is quickly dropped by the roller to achieve the separation of the conductor and the insulator.

Electrostatic separation is suitable for the separation of materials with different conductive properties of each component, such as the separation of some metal ores, the separation and recovery of scrap steel scraps, etc. In the electronic waste recycling production line, it is mainly used to separate the mixed materials into three parts: semiconductor, plastic and non-ferrous metal. The high-voltage power supply produced by Dalian Teslaman Technology Co., Ltd. Ripple and other characteristics, can be widely used in electrostatic separation equipment.
