Eddy Current Separator

Product Introduction

The eddy current separator is a high-efficiency non-ferrous metal sorting device based on the principle of electromagnetic induction. Its core components include a high-frequency magnetic roller, sorting channel, and drive system. A rapidly rotating magnetic roller generates an alternating magnetic field. When non-ferrous metals (copper, aluminum, alloys, etc.) pass through this field with the material stream, they induce eddy currents and experience Lorentz forces, propelling them out of the material stream. Non-metallic materials continue along their original trajectory, achieving precise separation.

The equipment is suitable for multiple scenarios including construction and renovation waste, dismantled home appliances, and industrial waste residue. It features high sorting efficiency, high purity, stable operation, and easy handling, significantly increasing metal recovery value. It is a core sorting device in the resource recycling industry.

Core Advantages

The core component uses a rare-earth permanent magnet array high-frequency magnetic roller, optimally arranged to form a strong-gradient alternating magnetic field. The field strength is high and uniformly distributed, providing stable and efficient magnetic field support for sorting operations and effectively improving sorting accuracy and operational stability.

Equipped with an adjustable material guide device, the angle and position of the guide plate can be flexibly adjusted via a handwheel, precisely controlling the material drop trajectory and entry state into the magnetic field. This efficiently accommodates various types of solid waste containing non-ferrous metals of different types and particle sizes, enabling targeted and optimized sorting.

The entire machine features a modular layout, with core units (magnetic roller, drive system, sorting channel) that are compact and easy to disassemble and assemble. This reduces equipment maintenance difficulty and facilitates component inspection and replacement, ensuring long-term continuous and stable operation.

The equipment is equipped with a professional electrical overload protection system. When anomalies such as abnormal current or overload operation occur, it automatically triggers an alarm and shuts down, effectively preventing equipment damage from overloading. The core magnetic roller is treated for wear and corrosion resistance, the sorting channel uses wear-resistant materials, and key wear parts have high durability, making the unit suitable for complex working conditions with high dust and heavy impact. The entire machine adopts a modular sealed design that reduces dust ingress and minimizes component wear, resulting in strong overall equipment stability and a long service life.
