3 Terms and Definitions

For the purposes of this document, the terms and definitions given in GB/T 44200—2024 and the following apply.

The percentage of the mass of various impurities sorted out by the construction waste sorting system relative to the total mass of those impurities in the construction waste before sorting.

Substances in construction waste with an apparent density of less than 1000 kg/m^3, such as waste paper, waste plastic, wood chips, textiles, and organic plant matter.

3.3 light substance sorting equipment

Mechanical equipment that uses certain process technologies to separate light substances during construction waste treatment.

3.4 iron removal equipment

Equipment that uses magnetic fields to separate ferrous metals such as iron, cobalt, and nickel from construction waste.

3.5 brick-concrete sorting equipment

Mechanical equipment that uses technologies such as image recognition to separate bricks and tiles from recycled aggregate derived from construction waste.

3.6 water separation equipment

Mechanical equipment used in construction waste treatment that utilizes the buoyancy of water or the impact force of water flow to separate light substances from waste concrete, bricks, etc.
