Construction Waste

Technical Overview

Construction waste is transported to the factory's stacking area and pre-sorted by excavators, then conveyed to a heavy-duty screening machine. The heavy-duty screen separates materials into oversize, middle-size, and undersize fractions. The undersize fraction consists of mixed slag and soil; the middle-size fraction passes through a magnetic separator to remove magnetic metals, and the remaining materials are conveyed to a high-pressure density separator to separate heavy and light materials. The heavy materials are conveyed to an impact crusher by a conveyor belt. The oversize fraction undergoes manual sorting, and the remaining materials are transported to the impact crusher after passing through a magnetic separator. The impact crusher crushes the materials, which are then conveyed to a vibrating screen. The vibrating screen separates aggregates of different particle sizes, which are then transported by a conveyor belt to corresponding aggregate storage bins for temporary storage.

Project Cases

Yingtan Project

The total scale is 10,000 tons/year for bulky waste disposal, and 100,000 tons/year for construction decoration waste disposal (of which the scale of decoration waste is 70,000 tons/year, and construction waste is 30,000 tons/year). The daily processing capacity for bulky waste is 300 tons/day, and for construction waste, it is 300 tons/day, with a single line disposal and a daily processing time of 10 hours.

Shenzhen Dakonggang Construction Waste Resource Utilization Project

The demolition and construction waste design treatment scale is 500,000 tons/year, and the project earthwork scale is 2,000,000 tons/year. The single-line capacity for regenerated pressed bricks ranks first in Asia.
As Shenzhen's first construction waste treatment project, it is a pioneer in the large-scale, resource-based collaborative disposal of demolition and construction waste in China. The project adopts BIM three-dimensional design and constructs a smart factory design concept to achieve the coordination of social, economic, and ecological benefits.
