[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration and repair. According to the source of generation, construction waste can be divided into engineering slag, decoration waste, demolition waste, engineering mud, etc.

[0003] For example, a multifunctional construction waste treatment equipment (announcement number: CN218222541U) includes a box body, a screening mechanism for screening construction waste is provided at the lower end of the box body, a second rotatable crushing mechanism is provided in the middle of the box body, a first slidable crushing mechanism is provided at the top of the box body, a top connecting piece for feeding is provided at the top of the box body, and a discharge port B is provided at the bottom of the box body. This multifunctional construction waste treatment equipment makes the crushing effect of construction waste more efficient and the treatment effect is better by setting the first crushing mechanism and the second crushing mechanism.

The driving part 54 in the screening mechanism 5 cooperates with the supporting part 53 to screen the crushed construction waste of different sizes on the screen 52, so that construction waste of different sizes falls from different outlets for different treatment. After the construction waste is crushed and screened, the first electromagnetic plate 42 and the second electromagnetic plate 45 can be controlled to be de-energized through the control panel 9, so that the metal adsorbed on the first electromagnetic plate 42 and the second electromagnetic plate 45 falls and is discharged.
