In the context of urban renewal and the construction of zero-waste cities, the disposal of urban construction waste has become a key indicator to measure urban governance. Faced with a huge amount of demolition waste and decoration waste, the traditional "excavation-transport-landfill" model is no longer viable. With the core concept of turning waste into reusable resources, Shanghai Dongmeng Heavy Industry provides one-stop solid waste recycling solutions covering scheme design and equipment delivery for customers nationwide with reliable construction waste crushing equipment.

1. Core Pain Points of Construction Waste Disposal

Urban construction waste has complex components, including waste concrete, bricks and stones, mixed with steel bars, wood scraps, plastics and muck. To realize resource recovery, three major problems must be solved: impurity removal, crushing and meeting environmental protection standards. With stricter environmental inspections and limited mining of natural sand and gravel, the industry is in urgent need of a standardized process integrating crushing, screening, sorting, iron removal and dust control.

2. Breakthrough: Dongmeng’s Construction Waste Treatment Equipment and Process Technology

To address the above pain points, Shanghai Dongmeng has developed a mature treatment process, including five core procedures: pre-sorting and soil removal, multi-stage crushing, magnetic iron removal, light material separation and screening forming.

In practical projects, Dongmeng usually adopts the technological design of two-stage crushing and closed-loop screening:

• Primary coarse crushing: Adopt mobile jaw crushing plant or heavy-duty feeder to crush large construction waste to below 150mm.
• Iron removal and material sorting: Recycle steel scrap by high-strength magnetic separator; separate wood and plastic with variable-frequency negative pressure air separation system with a purity of over 98%.
• Secondary fine crushing and screening: Use impact crusher or cone crusher for fine crushing, and produce multi-specification high-quality recycled aggregates of 0-5mm, 5-10mm, 10-31.5mm with multi-layer screening machines.

3. Foundation: Dongmeng Equipment Manufacturing Factory

Theory must be supported by solid equipment manufacturing. Relying on the industrial chain advantage of Shanghai, Shanghai Dongmeng has accumulated rich technical experience in mobile crushing and screening equipment.

The equipment factory mainly has two major product lines:

• Mobile processing equipment: Aimed at scattered demolition sites requiring on-site treatment, Dongmeng developed crawler-type and wheeled mobile crushing stations. The equipment requires no complex infrastructure and can drive into construction sites flexibly. Equipped with hydraulic drive and folding structure, it is easy to transfer, especially suitable for small and medium-sized demolition and decoration waste treatment projects.
• Fixed production line: For large centralized disposal centers, Dongmeng provides modular fixed production lines equipped with dust removal and noise reduction facilities, featuring large capacity and high automation to meet large-scale operation demands.

Integration: Dongmeng’s One-stop Solution for Urban Construction Waste

Shanghai Dongmeng is not merely an equipment manufacturer, but a one-stop solution provider for solid waste recycling.

For specific project cases, the service process is as follows:

• Customized scheme: Work out general layout and process flow according to the composition of construction waste, site area and finished product application.
• Equipment integration: Supply complete self-produced equipment including feeders, crushers, screening machines, dust removal and iron removal systems to guarantee matching performance and stable operation.
• Environmental compliance: The scheme is equipped with spray dust suppression system and sound insulation devices. Production water is recycled, and the discharge of dust and noise is better than national standards, helping customers avoid environmental risks.

4. Value Realization: Turn Construction Waste into Valuable Resources

The resource recovery rate of construction waste treated by Dongmeng’s system can exceed 90%. Recycled aggregates can be used in road base courses, permeable bricks and slope protection blocks. Waste metal is resold, and light materials are made into RDF fuel rods to realize full resource utilization.
