01 / Equipment overview
Equipment overview
A downstream finishing stage for prepared conductive/non-conductive particles, not a machine for whole PCBs, cables or batteries.
The Electrostatic Separator is a dry high-voltage separation machine for dividing conductive and non-conductive particles according to their different electrical behavior in an electrostatic field. It is used as a downstream upgrading stage for prepared copper/plastic, aluminum/plastic, PCB and selected mixed-plastic fractions. The separator is intended for controlled, free-flowing particles rather than whole or bulky scrap. Stable feed size, low moisture and suitable upstream liberation are important for consistent trajectories and product quality.

02 / Operating Principle
How the Electrostatic Separator Works
Mixed granular material enters through the upper feed inlet and is distributed across the internal conveying section. As the material passes through the electrostatic separation zone, conductive and non-conductive particles respond differently to the electric field, allowing the separated fractions to move toward their respective discharge paths.
02
Feed Distribution
The material is spread into a controlled layer and conveyed horizontally toward the electrostatic treatment zone.
03
Electrostatic Separation
Conductive and non-conductive particles follow different trajectories under the applied electric field and separate into distinct fractions.
04
Fraction Discharge
The separated material fractions move downward and leave through the lower collection and discharge outlet.

09 / Equipment FAQ
Common selection questions
What material size is suitable?
The feed should be liberated, dry and within a relatively controlled particle-size range. The acceptable range must be determined by sample testing because it depends on the selected drum, electrode and feed system.
Can it process a whole PCB, cable or battery?
No direct assumption should be made. Whole or bulky items require upstream dismantling, shredding and screening before electrostatic separation.
How is the final purity determined?
Purity and recovery depend on feed composition, liberation, moisture, particle size, voltage, drum speed, splitter position and recirculation. They should be established from representative test results rather than treated as fixed catalogue values.
Is middlings recirculation included?
It can be included as a conveyor or return elevator when required by the process design. Confirm the layout and control method in the quotation.
What information is needed for a quotation?
Provide material photos or samples, composition, particle-size distribution, moisture, required capacity, target products, desired purity/recovery, installation country, site power and available layout.
