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:

Parameter	Standard Model	Premium Model
Throughput Capacity	12 t/h	28 t/h
Particle Size Range	2-150 mm	0.5-200 mm
Aluminium Recovery	92%	97.5%
Power Consumption	25 kWh/t	18 kWh/t

Manufacturer Performance Benchmarking

Vendor	Model	Capacity	Warranty	ROI Period
EcoTech	ECS-3000	22 t/h	5 years	14 months
MetalSep	MagnaSort Pro	18 t/h	3 years	18 months
PureCycle	AluMaster+	30 t/h	7 years	22 months

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
