What are the processes for intelligent sorting of construction and Decoration waste?

With urbanization, the disposal of construction and Decoration waste has become an unresolved issue. Therefore, establishing a professional construction and Decoration waste resource utilization center is crucial. Henan Guoxin Machinery Co., Ltd., a company with extensive experience in household and stale waste sorting equipment, construction waste treatment, and Decoration waste screening, offers a range of equipment and system solutions, including vibrating screens, drum screens, bar screens, butterfly screens, bouncing screens, magnetic separators, eddy current separators, shredders, crushers, and fully automatic balers, as well as corresponding project solutions and equipment installation and maintenance services.

The following is a detailed description of the intelligent sorting process for construction and Decoration waste:

Preliminary Screening: After manual preliminary sorting, the construction and Decoration waste material is fed by a loader into a vibrating feeder. The material is screened by grates. Material smaller than the interstices between the grates is conveyed by a belt conveyor to a magnetic separator for iron screening. Material larger than the interstices between the grates is directly fed to the crusher inlet for crushing.

Primary Crushing: Materials larger than the screen size are fed into a crusher. After multiple stages of crushing, they pass through a magnetic separator to remove iron. Separated magnetic metals, such as rebar, are conveyed out of the facility via a conveyor belt for recycling.
Primary Sorting: Aggregates that have undergone iron removal are mixed with aggregates conveyed from the initial screening process in an air separator. The air separator uses wind power to separate lightweight materials, such as plastic, paper, and wood chips. Construction aggregates can be recycled, while lightweight materials can be packaged for processing.

Closed-Circuit Circulation: After the construction waste completes the complete crushing, screening, and impurity removal process, larger materials can be returned via a return conveyor for further processing, creating a closed-circuit circulation system to improve crushing efficiency.

Environmentally Friendly Production: To reduce noise and dust pollution, the production site is equipped with noise reduction and dust removal equipment, such as fog cannons and sprinklers. These devices help reduce dust and secondary pollution during the processing of construction waste, protecting the surrounding environment and ensuring environmentally friendly production.
Henan Guoxin Machinery Co., Ltd. uses these advanced process flows and technical equipment to provide efficient and environmentally friendly solutions for the treatment of urban construction and decoration waste, contributing to the sustainable development of the city.
