In the field of waste circuit board recycling, physical separation technologies are widely used for their environmental friendliness and high efficiency. Among them, water separation, air separation and dry separation have become the mainstream solutions, each with unique advantages in practical applications.
Water Separation: High Precision & Stable Recovery Rate
Water separation uses water as the medium and separates materials according to density difference.
- High separation accuracy, ensuring thorough separation of metals and non-metals, greatly improving the purity of recycled copper.
- Stable performance, low metal loss rate, and high resource utilization.
- Equipped with a circulating water treatment system, realizing water recycling and meeting environmental protection requirements.
Air Separation: Fast Pre-Treatment & High Efficiency
Air separation completes the separation through wind power, mainly used for material pre-treatment.
- Fast sorting speed, effectively removing light impurities such as dust and plastic films.
- Water-free process, no waste water discharge, simple process and low operation cost.
- Stable and reliable, suitable for continuous production lines to improve overall efficiency.
Dry Separation: Environmentally Friendly & Wide Application
Dry separation is a totally dry physical separation technology without water participation.
- Zero wastewater discharge, complying with strict environmental protection standards.
- No drying process needed after separation, shortening the production flow and reducing energy consumption.
- Wide applicability, suitable for various types of waste circuit boards, with high degree of automation.
Conclusion
Water separation, air separation and dry separation each have their own applicable scenarios.
Water separation achieves high-purity separation; air separation excels in rapid pre-treatment; dry separation provides outstanding environmental and economic benefits.
The rational selection and combined application of these technologies can effectively improve the recovery efficiency, reduce production costs, and promote the green and sustainable development of the waste circuit board recycling industry.
