Eddy Current Separator with PLC Control for Printed Circuit Board Recycling

Eddy Current Separator with PLC Control for Printed Circuit Board Recycling

Product Description:

This high-frequency eddy current separator targets fine non-ferrous metals in the 1 mm to 4 mm size range which are typically difficult for conventional separators to recover. The machine achieves this through an eccentric rotor design that spins at 4500 to 5500 RPM creating an alternating field with a very short wavelength. The working width of 600 mm processes 1 to 2.5 tons per hour of fine PCB millings or cable chopper fines. A 3 kW motor drives the rotor with ceramic bearings that withstand high rotational speeds. The belt is 4 mm thick anti-static polyurethane with a mirror-polished surface that minimizes material adhesion. The frame is constructed from 4 mm stainless steel with a brushed finish and sealed welds to prevent dust accumulation. A micrometer-adjustable splitter baffle provides precise cut point control with 0.2 mm resolution. The feed system includes a vibratory tray feeder with variable amplitude control to ensure uniform monolayer distribution. The magnetic rotor housing incorporates cooling fins to dissipate heat generated during high-speed operation. This machine is commonly used after a fine grinding mill and before an electrostatic separator in high-purity metal recovery lines.

Product Introduction

This Eddy Current Separator (ECS) is an advanced sorting system designed to automatically eject non-ferrous metals (aluminium, copper, zinc, brass) from mixed solid waste streams. Built for continuous operation in Municipal Solid Waste (MSW) facilities, Incinerator Bottom Ash (IBA) recovery lines, and single-stream recycling centers, it transforms low-grade residue into profitable metal fractions.

Target Applications

• Municipal Solid Waste (MSW) Treatment Plants:

  Recovers beverage cans, aluminum foils, and small non-ferrous fragments from the heavy fraction after primary crushing / bag opening.

• Incineration Bottom Ash (IBA) Valorization:

  Extracts valuable non-ferrous metals from bottom ash, maximizing resource recovery and reducing disposal costs.

• Scrap Metal Recycling (Zorba Upgrading):

  Purifies shredded non-ferrous mixtures (Zorba) into high-grade copper, aluminum, and magnesium for smelters.

• Glass / Plastic Purification Lines:

  Removes metal contaminants from crushed glass (cullet) or plastic flakes to protect downstream shredders and improve end-product purity.

Key Advantages for Heavy-Duty Waste Streams

Separation Efficiency Guarantee

Up to 98% recovery rate for aluminium cans (20-50mm size) and 85-92% for fine non-ferrous particles (2-10mm), verified in real MSW plants.

Technical Specifications (Standard Range)
