The use of a high-voltage electrostatic separator significantly improves the separation of metals and non-metals, especially in circuit board recycling. After crushing, the materials are broken into smaller particles, making it easier to separate metals like copper and aluminum from plastics and other non-metal materials. The electrostatic separator uses static electricity to enhance the purity and recovery rate of metals, offering a more efficient, automated, and environmentally friendly solution compared to traditional methods. This combination boosts separation accuracy and resource utilization.
