The correct eddy current separator should match the particle size distribution, material characteristics, and required hourly throughput of the recycling plant. Fine particles may require specialized rotor configurations, while coarse scrap requires suitable magnetic field exposure and adequate conveying capacity. Conveyor width, belt speed, material-layer depth, and feeding uniformity must also be considered. Before ordering, request material testing to verify both metal recovery and concentrate purity under representative operating conditions.

Particle size is one of the first specifications buyers should provide.

Do not describe the feed only as "shredded metal." Record the minimum and maximum particle size, the percentage in each size range, and the shape of the particles.

Fine flakes, irregular fragments, and large pieces may behave differently in the magnetic field.

Review the Eddy Current Separator and its role in modern recycling plants.

Different rotor arrangements and magnetic field characteristics suit different separation duties.

Fine electronic scrap may require a more specialized configuration. See high-precision e-waste ECS technology and non-ferrous recovery from electronic waste.

For mixed plastic and metal streams, compare automatic plastic and non-ferrous sorting equipment with sorting solutions for recycling lines.

Required throughput should be expressed in tons per hour and based on actual feed conditions.

Check:

• Average and peak feed rate.

• Bulk density and metal content.

• Conveyor width and speed.

• Material burden depth.

• Feeding consistency.

• Operating hours and planned downtime.

A wider conveyor does not automatically guarantee higher recovery. Excessive feed depth can cause particle overlap and unstable separation.

For integrated systems, consider automated sorting for recycling factories, complete metal recycling line engineering, and complex feedstock line configuration.

A vibrating screen machine can help prepare more consistent size fractions.

Ask the supplier to test representative material at the expected feed rate. Record recovery rate, concentrate purity, and material losses.

Do not compare quotations using nominal tons per hour alone.

The best separator is not necessarily the largest model. It is the configuration that can handle the actual particle size distribution and required throughput while meeting the plant's recovery and purity targets.
