Aluminum Profile Crushing and Sorting Process
1. Material Inspection and Feeding
Aluminum profile scrap should be checked before feeding. Oversized steel parts, sealed components, glass and other unsuitable materials should be removed or handled separately. Prepared profiles are then transferred into the line by a conveyor or other suitable feeding system.
2. Optional Primary Shredding
Long profiles, complete window and door frames, bundled material and scrap exceeding the crusher feeding limits may first pass through a twin shaft shredder. The shredder uses low-speed, high-torque shearing to reduce bulky material into shorter, coarse pieces and provide more stable feeding for the downstream crusher.
Primary shredding is optional. Properly sized profile offcuts and pre-cut aluminum sections may be fed directly into a suitable crusher.
3. Hammer Crushing
The aluminum profile crusher uses a high-speed rotor and hammer system to impact, deform and break the prepared material. The hammers, liner plates and screen grate work together to reduce the profiles into smaller pieces and open hollow sections for downstream separation.
4. Output Size Control
Material smaller than the screen openings is discharged from the crushing chamber, while oversized pieces remain inside for further crushing. The screen opening is selected according to the downstream sorting process and required output condition.
5. Ferrous Metal Removal
After crushing, a magnetic separator can recover exposed ferrous components such as screws, steel brackets, hinges and iron fittings. The separation result depends on material size, material depth, feeding uniformity and magnetic separator configuration.
6. Optional Screening and Eddy Current Separation
Screening or material spreading equipment may be added when the crushed output contains a wide particle size distribution or when more uniform feeding is required before subsequent sorting.
After ferrous metal removal and suitable material preparation, an eddy current separator may be used to recover conductive non-ferrous metals from an appropriate non-metallic material stream.
An eddy current separator does not normally separate mixed aluminum, copper and other non-ferrous metals into individual high-purity products. Additional sorting equipment may be required when separate metal fractions are needed.
7. Optional Airflow Sorting and Dust Collection
Airflow sorting can be considered when the processed material contains protective film, loose plastic, rubber, foam or other light impurities. Dust collection can be configured around the crusher, transfer points and screening equipment according to the material condition and workshop requirements.
8. Material Collection
The processed material is discharged into separate collection areas according to the selected crushing and sorting process. The final recovered fractions depend on the feed composition and installed separation equipment.
Typical Aluminum Profile Crushing Plant Configurations
Basic Crushing Configuration
Suitable for short, loose and prepared aluminum profile offcuts that meet the crusher feeding requirements.
Feeding Conveyor → Aluminum Profile Crusher → Discharge Conveyor → Magnetic Separator
Crushing and Non-Metallic Separation Configuration
Suitable for prepared aluminum profiles containing plastic strips, rubber, protective film or other non-metallic attachments.
Feeding Conveyor → Aluminum Profile Crusher → Magnetic Separator → Screening or Material Spreading → Eddy Current Separator → Optional Airflow Sorting
Primary Shredding and Crushing Configuration
Suitable for long profiles, complete window and door frames, bundled material or scrap that cannot be fed steadily into the crusher.
Feeding Conveyor → Twin Shaft Shredder → Transfer Conveyor → Aluminum Profile Crusher → Magnetic Separator → Optional Screening and Sorting
These configurations are examples rather than fixed equipment lists. The final process depends on the incoming material, required capacity, expected output size and separation objective.
