In actual operation, the construction waste entering the sorting system of the present invention generally needs to be pretreated, and the pretreatment includes

Primary crushing step: the construction waste is subjected to primary crushing treatment, so that the size of the construction waste is smaller than the set value, and a part of the metal waste is initially separated by magnetic screening;

Primary separation step: send the construction waste after preliminary separation to the vibrating screen, screen out powdery waste, and continue to transport the remaining waste. After wind screening, part of the light waste is separated, and then magnetic screening is performed again to separate part of the metal waste.

The construction waste through the initial separation step is sent to the sorting system in this embodiment. However, since a lot of metal waste is contained in concrete or gravel, it is difficult to separate during the initial magnetic screening, and there are often omissions. Therefore, multiple magnetic screenings are required.

The feeding device 10 in this embodiment combines magnetic screening with the rollers at the end of the feeding belt 11, so that the construction waste can be magnetically screened once every time it is conveyed, and before entering the washing machine 20, it is magnetically screened again to separate the residual waste.
