What is an electrostatic separator?
An electrostatic separator is an advanced equipment that utilizes the difference in material conductivity to achieve separation under the action of a high-voltage electrostatic field. It is not like a magnetic separator that only targets ferromagnetic metals, but can effectively separate various non-ferrous metals (such as copper, aluminum) and different types of plastics, making it a key equipment for achieving fine sorting of “urban minerals”.

Main application areas

Electrostatic separators play an irreplaceable role in the following fields:
Electronic waste recycling: Efficiently recover precious metals (gold, silver, copper, etc.) and resin powders from waste circuit boards (PCBs).
Scrap car recycling: Separate non-ferrous metals and plastics from crushed materials to improve resource reuse efficiency.
Cable and wire recycling: replacing traditional incineration methods, cleanly separating copper/aluminum cores and plastic sheaths.
Mixed plastic sorting: In the plastic recycling industry, it is used to separate plastics of different materials such as PVC, PE, PP, ABS, etc.

How does an electrostatic separator work?

The working principle of an electrostatic separator: The crushed and dried material is uniformly sent to a high-speed rotating grounding drum; At this point, the electrostatic field generated by the high-voltage electrode instantly charges all materials. Conductive metals quickly carry away charges and are adsorbed by the drum due to electrostatic induction; However, non-conductive plastics are strongly repelled due to the accumulation of same-sex charges. It is precisely this difference in charged characteristics that causes the separation of the motion trajectories of metal and plastic on the drum – plastic is quickly “bounced” into the front collection bin, while metal is carried by the drum to the rear and falls, thus achieving one-step, pure and efficient dry separation.
