Purpose and Boundaries
Recover Metal Fractions from Prepared Mixed Material
The line page explains the complete system rather than repeating one machine page.
Automatic separation works best after suitable size reduction, liberation, ferrous removal, screening and uniform spreading.
One separator does not normally produce every metal grade as a separate high-purity product. Additional sorting may be required.
Typical Objective
Recover exposed ferrous metal and separate conductive non-ferrous metal from non-conductive residue.
Separate Evaluation
Bulky, tangled, wet, sticky or iron-rich feed and uncontrolled particle sizes need pre-treatment.
Optional Expansion
Shredding, crushing, airflow, density separation, sensor sorting and manual inspection.

Mixed Metal Sorting Line Overview
The mixed metal sorting line is designed for suitably prepared material containing ferrous metal, conductive non-ferrous metal and non-metallic residue. The process may combine size reduction, magnetic separation, screening, controlled feeding and eddy current separation.
Automatic sorting performance depends heavily on material preparation. Bulky, tangled or insufficiently liberated scrap should not be fed directly into the sorting equipment.
Feed Preparation Requirements
The incoming material should have a suitable particle-size range and be capable of forming a stable layer on the feeding conveyor. Excessive moisture, sticky contaminants, wide particle-size differences and overlapping material can reduce separation stability.
Shredding or crushing may be required when valuable metals remain attached to plastic, rubber or other materials. Screening is then used to create narrower size fractions before automatic sorting.
Magnetic and Eddy Current Separation
Magnetic separation is normally performed before eddy current separation to remove exposed iron and steel. Excessive ferrous contamination can interfere with downstream sorting and affect equipment operation.
The remaining material is fed evenly into the eddy current separator. Conductive non-ferrous particles react to the changing magnetic field and are discharged separately from suitable non-conductive residue.
An eddy current separator does not normally divide aluminum, copper, zinc and brass into individual high-purity products. If separate metal grades are required, the line may need density separation, sensor-based sorting, X-ray sorting, optical sorting or manual inspection.
Material Testing and Line Selection
Please provide representative samples or clear material photos and videos, together with particle-size distribution, composition, moisture condition, required capacity and target recovered products. Testing is recommended when the feed contains several metals with similar sizes or uncertain liberation.
The final configuration may include a crusher or shredder, magnetic separator, vibrating screen, controlled feeder, eddy current separator, airflow separator and separate collection conveyors. Each stage should be selected according to the actual material and required recovered fractions.

Frequently Asked Questions
Questions Specific to the Complete Line
Can one eddy current separator produce pure aluminum, copper and zinc products?
Not normally. An eddy current separator mainly separates conductive non-ferrous metals from suitable non-conductive material. It does not usually divide aluminum, copper, zinc and brass into separate high-purity products. Additional density separation, sensor-based sorting or manual sorting may be required for individual metal grades.
Why must iron be removed before eddy current separation?
Excessive ferrous contamination can affect separation stability and interfere with downstream equipment. A magnetic separator is normally installed before the eddy current separator to remove exposed iron and steel from the prepared material stream.
Can bulky mixed scrap enter the sorting line directly?
No. Bulky, tangled or insufficiently liberated scrap normally requires shredding or crushing before automatic sorting. The prepared material should have a suitable particle-size range and be capable of forming a stable layer on the feeding conveyor.
Why is screening required before automatic sorting?
Screening divides the prepared material into narrower particle-size fractions. Material with large size differences may not travel or respond consistently during separation. A more controlled particle-size range helps improve feeding stability and allows the sorting equipment to operate under more suitable conditions.
Can wet or sticky material be processed effectively?
Excessive moisture, oil, mud and sticky contaminants can cause particles to adhere to each other, overlap on the conveyor or accumulate inside the equipment. The material may require drying, cleaning or another preparation stage before screening and automatic sorting.
When is additional density or sensor-based sorting required?
Additional sorting may be required when the project needs separate aluminum, copper, zinc, brass or stainless steel products rather than one mixed non-ferrous fraction. The appropriate method depends on particle size, material liberation, density, conductivity and the required final product quality.
