Understanding Aluminium Eddy Current Separation

Eddy current separation has revolutionized aluminium recovery in scrap processing, achieving 95-98% purity rates in industrial applications. This non-contact technology uses magnetic fields to repel conductive metals, enabling efficient segregation of aluminium from mixed waste streams. Modern systems process up to 25 tonnes/hour while consuming only 18-22 kWh/tonne, making them indispensable for sustainable metal recycling.

Technical Superiority in Metal Sorting

Advanced eddy current separators feature dynamic rotor systems (1,800-4,200 RPM) and AI-powered material recognition. Key metrics demonstrate superiority:

Third-party testing reveals EcoTech's dual-frequency technology reduces non-ferrous metal loss by 41% compared to industry averages.

Tailored System Configurations

Modular designs allow custom throughput scaling from 5 t/h to 50 t/h installations. Smart control systems adapt to variable material composition, maintaining 94% efficiency across different feedstock types. Typical configurations integrate:

  • Variable belt speeds (1-4 m/s)
  • Multi-stage separation chambers
  • Real-time metal purity sensors

FAQS on aluminium eddy current

Q: How does an eddy current separator work for aluminium recycling?

A: Eddy current separators use a rotating magnetic field to induce eddy currents in aluminium, repelling non-ferrous metals and separating them from other materials during recycling.

Q: What are the benefits of using an eddy current separator for aluminium scrap?

A: It ensures high-purity aluminium recovery, reduces contamination, and improves processing efficiency in scrap recycling plants.

Q: What factors affect the capacity of an eddy current separator for aluminium separation?

A: Capacity depends on material feed rate, particle size, belt speed, and magnetic rotor strength, typically ranging from 5-50 tons per hour.

Q: How much maintenance does an aluminium eddy current separator require?

A: Minimal maintenance is needed, primarily involving belt inspections, rotor cleaning, and occasional bearing replacements for optimal performance.

Q: What is the typical cost of an aluminium scrap recycling plant with eddy current separation?

A: Costs range from $500,000 to $3 million, depending on separator capacity, automation level, and auxiliary equipment like shredders or conveyors.
