Here is a systematic introduction to the core equipment for sorting construction waste, including functions, applicable scenarios, and commonly used combination processes:
1、 Front end preprocessing&fragmentation
1. Vibration feeder: evenly conveying large pieces of construction waste to the crusher, anti blocking, adjustable speed; Adapt to demolition sites/disposal sites
2. Jaw/impact crusher: coarse crushing+medium crushing, reducing concrete blocks and bricks to the appropriate particle size (such as ≤ 300mm → ≤ 50mm); Heavy duty wear-resistant, suitable for high hardness materials
3. Mobile crushing and screening station: integrated vehicle mounted, on-site operation does not require civil engineering; Suitable for projects with short construction periods and multi-point transportation

2、 Screening equipment (graded particle size)

1. Vibration screen/drum screen: The vibration screen has precise grading (5/10/20/50mm); Drum screen is impact resistant and suitable for wet/sticky materials; Used for grading aggregates
2. Bounce screen: Separate weight/size through collision bounce differences; Commonly used for initial sorting of decoration waste, with high efficiency

3、 Core sorting equipment (material classification)

1. Magnetic separator (drum/suspension): strong magnetic field adsorbs steel bars and iron nails; The metal recovery rate is often greater than 98%; Essential link
2. Air separator: air separation of light materials (plastic film, wood chips, foam) and heavy aggregates; Low cost and environmentally friendly
3. Eddy current separator: separates non-ferrous metals such as aluminum and copper; Recovery rate of 85% -95%; Suitable for refined recycling lines
4. AI vision/optoelectronic sorting: high-definition camera+deep learning recognition of concrete, bricks, plastics, and wood; Sorting purity>80%; Suitable for high value-added regeneration lines

4、 Auxiliary environmental protection equipment
Pulse bag filter: Control dust (emission<10mg/m ³)
Sealed conveyor belt: reduces dust and noise
Intelligent electronic control system: monitoring parameters, automatic parameter tuning, fault warning

5、 Typical process flow
Feeding → coarse crushing → magnetic separation for iron removal → medium crushing → multi-stage screening → air separation for light substances → eddy current separation for non-ferrous materials → AI fine sorting → classification and discharge of recycled aggregates/metals/combustibles

6、 Key selection points
Small projects: Fixed line, priority vibration screen+magnetic separation+air separation;
Large scale demolition: mobile station+multi-level sorting, balancing efficiency and flexibility;
High resource utilization rate: By combining eddy current and visual sorting, the recovery rate of metals and lightweight materials is improved.
