Construction waste can be processed into renewable resources and recycled for production after multiple processes such as iron removal, winnowing, crushing, and screening with professional equipment.
Construction waste crushing process
Primary crushing: Construction waste is crushed for the first time, and then undergoes magnetic separation and primary screening to separate steel bars and miscellaneous soil. Magnetic separation: Separate steel bars from construction waste through an iron remover. Screening: Separate soil and construction waste.
Secondary crushing: After secondary crushing, light materials are first separated, and then the remaining construction waste is screened out according to certain standards through a professional screening system to produce various construction raw materials.
Crushing: Concrete blocks, bricks, etc. that have been broken once will be broken.
Winnowing: After secondary crushing, the light substances in the construction waste are separated through winnowing.
Screening: After the light materials are separated, different building stones, sand, wood, etc. are generated through the screening system according to the particle size and recycled into production.
Advantages of construction waste crusher
Crushing is an important process in construction waste disposal. Currently, the most commonly used equipment for construction waste treatment is mobile crushing station equipment, which has the following advantages:
1. No foundation or supporting construction is required, and it can be easily processed at the demolition site;
2. The workstation can be moved quickly, eliminating the material dumping process and reducing regeneration costs.
3. It can be flexibly combined and matched under different working conditions to reduce investment costs;
4. The equipment is easy to operate and maintain, reducing personnel investment costs;
5. The equipment is equipped with sound insulation equipment and dust removal equipment for dust prevention and noise reduction, and meets the national workshop environmental testing standards.
Construction waste recycling and resource utilization
(1) Use waste construction concrete and waste bricks to produce coarse and fine aggregates, which can be used to produce concrete and mortar of corresponding strength levels or to prepare building materials such as blocks, wall panels, and floor tiles. Coarse and fine aggregates can also be used as highway pavement base layers after adding curing materials;
(2) Use waste bricks and tiles to produce aggregates, which can be used to produce recycled bricks, blocks, wall panels, floor tiles and other building materials;
(3) Waste soil can be used for road construction, pile foundation filling, foundation foundation, etc.;
(4) For waste wooden construction waste, the wood that is not obviously damaged can be directly reused to rebuild buildings, and the severely damaged wooden components can be used as raw materials for wood recycled boards or paper making;
(5) Waste road asphalt mixture can be directly used in recycled asphalt concrete in appropriate proportions;
(6) Abandoned road concrete can be processed into recycled aggregate and used to prepare recycled concrete;
(7) Scrap steel, scrap steel bars and other scrap metal materials can be directly returned to the furnace for reuse or returned to the furnace for processing;
(8) Waste glass, waste plastic, waste ceramics and other construction waste are utilized according to the situation. Use professional equipment for crushing, screening, recycling and operation processes
