Construction waste refers to the spoil, waste, and other waste generated during the construction, reconstruction, demolition, and repair of various buildings and structures by construction units or individuals, as well as when residents decorate their houses. According to the source classification, construction waste can be divided into five categories: land excavation, road excavation, old building demolition, building construction and building materials production waste. It mainly consists of concrete blocks, brick fragments, muck, gravel blocks and waste mortar. It is composed of asphalt blocks, waste plastics, waste metal materials, waste packaging materials, waste bamboo wood, etc.
The current urban construction waste can be separated into different materials after crushing, sorting, screening, and cleaning, which can be used in different fields: wood block-board production; metal-metal recycling; plastic-plastic recycling; construction waste soil -Backfill material or paving.
What is left in the end are concrete blocks and brick residue.
Production process of concrete blocks and brick slag:
The construction waste generated after the demolition of buildings is pre-processed to a particle size that can enter the crusher, and then sent to the vibrating feeder by the excavator. The fine waste is pre-screened by the feeder and discharged, and the large waste is fed into the

The crusher crushes, and an iron remover is placed above the impact crusher discharge belt conveyor to separate the steel bars in the construction waste. After that, the materials enter the mobile screening station for screening. The large materials return to the impact crusher for cycle crushing, and the small materials are transported by the belt conveyor. to each finished product material pile.
Performance of construction waste treatment production line:
In addition to the feeding system, crushing system, screening system, and conveying system, the mobile construction waste treatment production line is equipped with its own power device according to the mobility of mobile operations. According to different crushing and screening operation processes, the structure of the equipment is also different.
1. Improve the utilization rate of equipment, have good maneuverability and extend with the site;
2. Save production costs: reduce the high costs incurred by construction waste transportation;
3. Convenient for supporting installation: saving basic installation costs and installation and adjustment manpower;
4. Easy maintenance: it can be directly shipped to the repair shop for maintenance;
5. Simplify the production process: advance along with the mining surface, simplifying the transportation link.
