The Electrostatic Sorting Machine is a high-efficiency separation equipment that uses electrostatic principles to sort materials with different electrical properties. When mixed materials pass through a high-voltage electric field, particles become charged and respond differently based on their conductivity. Conductive and non-conductive materials are then separated with high precision.
This dry separation process does not require water, making it energy-saving, environmentally friendly, and highly efficient in improving material purity while reducing manual labor and processing costs. The machine typically offers a processing capacity of 200–500 kg/h, making it suitable for small to medium-scale recycling operations.
This machine is widely used in recycling and resource recovery industries. It is commonly applied in plastic separation (such as PVC, PET, and ABS), electronic waste recycling for metal and plastic separation, cable recycling to recover copper and plastic, and mineral processing for fine particle sorting.

How does the electrostatic sorting machine work?
An electrostatic sorting machine works by separating materials based on differences in electrical conductivity inside a sealed high-voltage electric field. After pre-processing, mixed materials are fed into the separation chamber where they pass through a corona electric field generated by stainless steel electrodes. In this field, conductive and non-conductive materials become charged differently and respond in different ways to the electric force.
Under the combined action of electrostatic force, gravity, and centrifugal force, materials follow different trajectories and are collected separately at different outlets. This dry separation process requires no water or chemicals and enables efficient, high-purity recovery of metals and plastics from mixed waste such as aluminum-plastic and copper-plastic materials.
