Amidst the wave of modern urbanization, the booming construction industry has brought with it a significant challenge: the disposal of construction waste. This waste not only takes up a significant amount of space but also places a significant burden on the environment. To address this challenge, construction waste sorting technology has emerged. It not only promotes resource recycling but also helps reduce and harmlessly treat construction waste.

The core of construction waste sorting technology lies in effectively separating different materials within the waste by utilizing their physical and chemical properties. This method can separate different materials within construction waste, such as wood, masonry, metal, and plastic, laying the foundation for subsequent recycling and reuse.

Screening Technology

Screening technology is one of the fundamental methods for sorting construction waste. It uses screens to separate materials by particle size. Commonly used screening equipment in construction waste management includes fixed screens, vibrating screens, and drum screens.

Fixed screens: They have a simple structure, require no power, and are suitable for coarse screening.

Vibrating screens: They separate materials through vibration and are suitable for screening wet materials, processing coarse, medium, and fine particle sizes. Drum Screen: This screens materials using a rotating cylindrical screen surface and is suitable for separating fine particles.

Gravity Separation Technology

Gravity separation utilizes density differences in materials to achieve separation within a moving medium. This method includes wind separation, jigging, heavy medium separation, and inertial separation.

Wind Separation: This uses airflow to separate light materials from heavy materials and is suitable for separating light and heavy components in municipal waste.

Inertial Separation: This separates particles by projecting particles horizontally, utilizing the inertial differences between particles of different densities and sizes.

Magnetic Separation Technology

Magnetic separation technology uses magnetic differences to separate materials. Commonly used equipment includes magnetic separators, which can separate iron and iron oxides from construction waste.

CTN Permanent Magnet Drum Separator: Suitable for recovering iron and strongly magnetic particles from construction waste.

Magnetic Drum: Used to remove iron from waste prior to crushing to protect the equipment.

Suspended magnets: Also used to remove iron from construction waste.

In addition to the aforementioned methods, there are various other sorting methods, including friction sorting, ricochet sorting, and photoelectric sorting, which can be flexibly selected and deployed according to specific processing needs.

In short, the development of construction waste sorting technology provides an effective way to achieve resource utilization of construction waste, helping to promote green urban development and environmental protection. With technological advancement and innovation, we have reason to believe that these technologies will play an even more important role in future construction waste treatment.
