Production line equipment for sorting and recycling construction waste
What is construction waste?
Construction waste refers to the construction waste generated in the project due to man-made or natural reasons, including waste slag soil, waste soil, silt and waste materials. These materials are not of any help to the building itself, but they are substances produced in the process of construction, which need to be treated accordingly, so as to achieve the ideal construction project. Because it is a whole process, the consideration of its links is more important.
The hazards of construction waste
1. Random stacking of construction waste is easy to produce safety hazards. The site selection of most urban construction waste dumps is largely arbitrary. Under the influence of external factors, construction waste collapses, obstructing roads and even rushing to other buildings. In the suburbs, pits and ditches are the first choice for the storage of construction waste, which not only reduces the capacity of water regulation and storage, but also leads to the reduction of surface drainage and flood discharge capacity.
2. Construction waste is seriously polluting water resources. Construction waste in the process of stacking and landfill, due to fermentation and rainwater leaching, scouring, as well as surface water and groundwater soaking and leachate leachate or leachate, will cause serious pollution of the surrounding surface water and groundwater. Once drinking this polluted water, it will cause great harm to the human body.
3. Construction waste affects air quality. With the continuous development of the city, a large number of construction waste piled up at will, not only occupy land, but also pollute the environment, and directly or indirectly affect the air quality. When the construction waste is disposed by landfill, some organic substances decompose and produce harmful gases under the action of temperature and moisture during the stacking process. A small amount of combustible construction waste in the incineration process will produce toxic carcinogens, resulting in secondary pollution to the air.
4. Construction waste occupies land and reduces soil quality. With the increase of the amount of urban construction waste, the garbage dumping point is also increasing, and the area of the garbage dumping site is also gradually expanding. Most of the suburban garbage dumps are mainly stacked in the open, after a long period of sun and rain, the harmful substances in the garbage penetrate into the soil through the landfill leachate, resulting in a series of physical, chemical and biological reactions, resulting in the pollution of the suburban soil, thereby reducing the quality of the soil. In addition, under the action of various external forces, the urban construction waste stacked in the open air will enter the nearby soil, change the material composition of the soil, destroy the structure of the soil, and reduce the productivity of the soil.
Construction waste disposal methods
Steps:
Sorting → crushing → Packing
Machine:
Plate chain feeder → bar screen → manual sorting platform → Vibrating feeder → box crusher → iron remover → Vibrating screen → Finished sand stacking area
→ Roller screen → Belt conveyor → Vibrating feeder → box crusher → iron remover → Vibrating screen → Finished sand storage area
→ Roller screen → Air sorter → Belt conveyor → manual sorting platform → vibrating feeder → box crusher → iron remover → Vibrating screen → Finished sand stacking area
