AI Technical Summary
Existing vibrating screening devices suffer from serious dust pollution and inefficient yard management when processing construction waste concrete. In particular, the high rate of fine aggregate escaping and frequent cross-contamination between coarse and fine aggregates lead to environmental pollution and increased labor costs.
A screening device for recycled aggregates from construction waste concrete was designed. It adopts a closed screening chamber and an adjustable guide plate structure. The screening chamber is driven by a vibration motor for closed screening. Fine aggregates and coarse aggregates are output through different outlets. The angle of the guide plate is adjusted by an electric cylinder to achieve dynamic material balance and reduce dust discharge and collection frequency.
It effectively reduces dust pollution, improves space utilization, reduces labor costs, achieves efficient separation and unified collection of coarse and fine aggregates, breaks through the limitations of traditional fixed chutes, and achieves a dynamic balance between stockpile height and paving area.
