Abstract
An electrostatic separation system for separating fine metal and plastics is disclosed. An electrostatic separation system according to the present invention comprises a negative electrostatic induction plate and positive metal net made of special materials, which have appropriate dimensions and an appropriate space between them to improve separation efficiency, and a separating plate which is appropriately positioned to improve separation efficiency. The electrostatic separation system has processing capacity more than 5 times in comparison to conventional electrostatic selection systems and is able to separate fine particles of 0.1 mm in size. In addition, the electrostatic separation system has wide application in recycling other useful recourses as well as separating the mixture of fine particle metal and non-metal materials.
