The specific gravity separator machine is used to separate non-ferrous metals from non-metals and is widely used in the scrap recycling industry. They are particularly suitable for separating copper from plastic after shredding scrap wires and cables, as well as for separating copper, aluminum, and iron after shredding copper-aluminum radiators.
The machine features an integrated, compact design with a small footprint. It can be placed directly on a level surface, plugged in, and operated immediately, making it suitable for use in small-to-medium-sized and large-scale recycling production lines.
As the core component of the fine sorting process in copper granulator production systems, the equipment combines airflow suspension with the principle of density differences. When integrated with an electrostatic separation system, copper recovery purity can consistently reach 99.5% or higher. This further reduces residual copper in the plastic, ensuring the final sorting meets the high standard of “no plastic in the copper, no copper in the plastic.”

specific gravity separator working principle
The equipment utilizes differences in material density as the core principle of sorting. A vibrating conveyor system evenly spreads the crushed mixture, while an air suspension device causes materials of different densities to form distinct layers under the influence of airflow.
Heavier metal particles (such as copper and aluminum) settle under the force of gravity and are collected, while lighter plastics are carried by the airflow to different outlets, achieving efficient separation. By adjusting the vibration frequency and airflow intensity, the system can adapt to different material compositions and achieve precise sorting.
