Abstract:
1. An electrostatic separation system for separating fine metal and plastics, comprising: a feeder feeding input materials comprising conductive materials and nonconductive materials into a negative electrostatic induction plate; the negative electrostatic induction plate to which negative electricity is applied, the negative electrostatic induction plate moving the input materials by using a vibrator, the vibrator being installed under the negative electrostatic induction plate; a positive metal net to which positive electricity is applied, the positive metal net having a width equivalent to or larger than the negative electrostatic induction plate; and a separating plate positioned between the negative electrostatic induction plate and positive metal net, the separating plate separating the input materials into conductive materials and nonconductive materials, wherein the input materials having less than 0.1 mm in size are supplied at a feed rate of 150 g/min, and 40 kv is applied to the negative electrostatic induction plate and the positive metal net, and the vertical distance between the negative electrostatic induction plate and the positive metal net is 50 cm.
