Aluminum Can Briquette Purification
Effective impurity removal enhances aluminum purity, improves recycling value, and ensures stable performance during subsequent processing. The following methods optimize briquette quality and maximize economic benefits.
Pre-processing of Raw Materials
- Thoroughly clean collected aluminum cans to eliminate food residues, oil stains, and adhesives
- Use appropriate cleaning agents that do not corrode aluminum
- Ensure sufficient drying to prevent moisture-related issues
- Conduct careful sorting to separate aluminum cans from non-aluminum materials
- Utilize manual or mechanical sorting equipment for purity assurance
Physical Separation Methods
- Use air separation technology to blow away lightweight impurities like dust or paper scraps
- Install magnetic separation devices to attract and separate magnetic impurities such as iron scraps
- Utilize screening equipment to sift out impurities of different particle sizes
- Ensure uniform briquette composition through density-based separation techniques
Chemical Auxiliary Methods
- Apply mild chemical solvents compatible with aluminum for stubborn oil stains or organic residues
- Ensure solvents are environmentally friendly and can be fully rinsed off
- Use gentle chemical polishing or pickling processes for oxide layers or surface contaminants
- Maintain strict control of process conditions to prevent damage to aluminum briquettes
Quality Inspection & Control
- Regularly sample and test treated briquettes to check for residual impurities
- Adjust impurity removal methods promptly if excessive impurities are detected
- Establish a systematic impurity removal process covering all stages
- Implement closed-loop quality control system from pre-processing to post-treatment
In summary, removing impurities from aluminum can briquettes requires a combination of raw material pre-processing, physical separation, targeted chemical auxiliary methods, and post-inspection. By integrating these measures, the purity of aluminum can briquettes can be effectively improved, laying a solid foundation for high-quality recycling and reuse.
