Scrap Metal Recycling Line Solutions

Complete Scrap Metal Crushing and Sorting Line Solution

Haoxing Machinery provides complete scrap metal crushing and sorting line solutions for recycling plants, metal recovery centers and industrial scrap processing facilities. Each scrap processing line is configured according to the feed material, required throughput, target output size, separation objective and available installation space.

A complete system may combine a twin shaft shredder, scrap metal crusher, feeding and discharge conveyors, screening equipment, magnetic separation, eddy current separation, airflow sorting and dust collection. These stages work together to reduce bulky scrap, improve metal liberation and recover valuable ferrous and non-ferrous materials from mixed waste streams.

The process is selected according to the material rather than built around a fixed equipment list. Bulky or baled scrap usually requires low-speed, high-torque primary shredding before secondary crushing. Thin metal sheets and pre-cut materials may be fed directly into a suitable crusher. Mixed scrap containing plastics, rubber and other impurities may require additional screening and separation stages.

What Is a Scrap Sorting Line?

A scrap sorting line is an integrated recycling system used to process mixed scrap and separate it into recoverable material streams. Depending on the feed composition, the system can recover iron and steel, aluminum, copper-containing fractions and other valuable metals while removing plastics, rubber, dust and light fluff.

A typical line may include feeding equipment, primary shredding, hammer crushing, screens, conveyors, a magnetic separator, an eddy current separator, an air separator and a dust collection system. The exact configuration depends on material size, density, composition and the required quality of the final products.

The magnetic separator recovers iron and steel from the processed material. The eddy current separator recovers aluminum, copper and other conductive non-ferrous metals from non-metallic fractions. Screening controls particle size, while airflow separation removes light impurities.

An eddy current separator does not normally divide copper and aluminum into separate high-purity products. If individual copper and aluminum fractions are required, the non-ferrous separation system may need additional density separation, sensor-based sorting or other specialized equipment.

Typical Scrap Metal Sorting Process

Feeding → Primary Shredding → Hammer Crushing → Screening → Magnetic Separation → Eddy Current Separation → Airflow Sorting → Final Recovered Materials

Not every project requires every stage. The process can be simplified or expanded according to the raw material, required capacity, final output size, product purity and plant layout. Material testing is recommended when the feed contains several metals or a high proportion of non-metallic impurities.

Materials Suitable for Scrap Sorting Systems

Scrap crushing and sorting systems can be configured for different ferrous, non-ferrous and mixed scrap materials, including:

• Scrap steel and scrap iron

• Baled scrap metal

• Light mixed scrap

• Scrap cars and car body shells

• End-of-life vehicle scrap

• Household appliance shells

• Aluminum profiles and aluminum sheet scrap

• Cast aluminum parts and aluminum crankcases

• Motor rotors and stators

• Copper-aluminum radiators

• UBC aluminum cans

• Mixed industrial metal waste

• Metal waste from construction and demolition projects

Different materials should not be processed with the same standard configuration. Material size, thickness, bulk density, moisture, contamination level and composition should be evaluated before selecting the equipment. Photos, videos or samples of the raw material can help determine whether primary shredding, hammer crushing, magnetic separation, eddy current sorting or airflow separation is required.

Baled Scrap Shredding and Sorting Solutions

Baled scrap metal has a high bulk density and may contain compressed steel sheets, appliance shells, aluminum scrap, binding wire and mixed impurities. Bale dimensions, density, material thickness and internal composition should be checked before selecting the feeding, shredding and downstream separation equipment.

A baled scrap shredder uses low-speed, high-torque cutting to open compressed bales and reduce oversized material into a more manageable feed size. The cutter chamber, blade thickness, motor power and feeding method should be selected according to the bale dimensions, material composition and required throughput.

For continuous industrial processing, a baled scrap shredding plant may include a chain plate conveyor, twin shaft shredder, discharge conveyor, magnetic separator, screening equipment, dust collection system and PLC control system. Additional crushing and non-ferrous separation equipment can be added when the material requires further size reduction, metal liberation or recovery of aluminum and other conductive metals.

The final configuration depends on whether the project only requires bale opening and volume reduction or needs complete crushing, sorting and metal recovery. Material photos, bale dimensions, approximate composition and required processing capacity should be provided before equipment selection.

Main Equipment in a Scrap Metal Recycling Line

• Twin Shaft Shredder

• Scrap Metal Crusher

• Feeding and Discharge Conveyors

• Vibrating Screen or Trommel Screen

• Magnetic Separator

• Eddy Current Separator

• Air Separator

• Dust Collection System

• PLC Control System

The twin shaft shredder performs low-speed, high-torque primary size reduction for bulky, loose or baled materials. The scrap metal crusher uses high-speed hammer impact for secondary crushing and improved metal liberation. Screens control the material size entering each separation stage, while magnetic and eddy current sorting equipment recover the main metal fractions.

Recovered Materials and Separation Results

The final output depends on the feed composition, particle size and selected sorting equipment. A properly configured scrap sorting system may produce:

• Ferrous metal recovered by magnetic separation

• Aluminum and other conductive non-ferrous metals recovered by eddy current separation

• Copper-containing fractions for further sorting

• Stainless steel and other residual metal fractions

• Separated plastics and rubber

• Light fluff, dust and other impurities

Recovery rate and product purity vary with material composition, moisture, contamination and equipment configuration. Final performance should be evaluated through material testing rather than estimated from throughput alone.

Advantages of a Complete Scrap Sorting Line

• Combines size reduction, metal liberation and material separation in one process

• Recovers ferrous and non-ferrous metals from mixed scrap

• Reduces manual sorting requirements

• Improves the consistency and market value of recovered materials

• Supports continuous industrial production

• Can be adjusted for different scrap compositions and processing capacities

• Integrates dust collection and centralized PLC control

• Can be arranged according to the available plant dimensions

How to Select the Right Scrap Processing Line

Required throughput in tons per hour is important, but capacity alone is not enough to select a recycling line. Two materials with the same hourly weight may require different feeding systems, shredding power, crusher configuration, screen size and separation equipment.

Before preparing a production line proposal, the following project information should be confirmed:

• Raw material type and approximate composition

• Loose material, compressed bale or mixed scrap load

• Maximum feeding size and material thickness

• Bale dimensions and approximate bale weight, when applicable

• Required processing capacity per hour

• Expected output size

• Target metals or materials to be recovered

• Required product purity

• Available plant length, width and height

• Local power supply and environmental requirements

• Photos, videos or samples of the feed material

Custom Scrap Recycling Plant Solutions

Every recycling project has different raw materials, operating conditions and final product requirements. Haoxing Machinery can configure scrap metal crushing and sorting lines for scrap steel processing, baled scrap recycling, mixed scrap treatment and aluminum recycling applications.

Depending on the project, the recommended process may range from a simple bale opening and magnetic separation system to a complete shredding, hammer crushing, screening and non-ferrous separation line. Equipment selection and process design are determined after evaluating the customer's material, required throughput, separation objective and investment plan.

Based on the project information, Haoxing Machinery can provide equipment recommendations, process configuration, production line layout and technical support for recycling yards and industrial metal recovery facilities.
