How to Solve Construction Waste & Industrial Tailings Issues?

Summary: How to Solve Construction Waste & Industrial Tailings Issues? The Million-Ton Annual Recycling Project for Construction Waste and Industrial Tailings, successfully developed by SBM, provides a practical answer....

With the acceleration of urban construction and industrial production, large volumes of solid waste occupy land and pollute soil and water, while natural sand resources grow increasingly scarce. Efficiently recycling construction waste and industrial tailings has become a critical issue the industry must address.

SBM delivered a complete set of core equipment and customized processing solutions for the one Million-Ton Annual Recycling Project for Construction Waste and Industrial Tailings, offering the industry a green, sustainable development model.

Addressing Project Pain Points Head-On

For a long time, the treatment of construction waste and industrial tailings has remained stuck in the early stages of simple crushing, low utilization rates, and low added value. Most production lines can only process a single type of raw material. When faced with impurities like rebar, plastics, or soil in construction waste, or the highly abrasive nature of tailings, they often encounter issues such as:

· Rapid equipment wear

· Unstable product quality

· High operating costs

· Frequent breakdowns

· Poor economic returns

What the market truly needs is not just equipment to handle waste, but a systematic solution that guarantees high-quality recycled aggregates and long-term sustainable development. This is precisely why, after evaluating multiple suppliers, the client ultimately chose SBM as their technical partner.

SBM’s Customized Solution

SBM analyzed client needs and material characteristics, proposing a tailor-made crushing and sand-making solution that achieves a fully closed-loop system—from "waste input" to "green building materials output." The project has since become a government-endorsed, media-highlighted demonstration project.

Flexible Process Design: Dual-Material Compatibility

For construction waste and industrial tailings, SBM developed differentiated processing solutions:

· For Construction Waste:

Multi-Stage Crushing + Impurity Removal + Lightweight Material Separation + Magnetic Iron Removal.

After initial feeding via a vibrating feeder, raw materials enter the SBM-PEW Jaw Crusher for coarse crushing; Multi-stage iron removal, impurity separation, and soil washing eliminate contaminants like rebar, plastics, wood, and mud; PFW Impact Crusher handles medium crushing, while the VSI5X Sand Maker shapes the material for refined gradation. Finally, precision screening produces different specifications of high-quality recycled aggregates.

· For Industrial Tailings:

Given their high hardness and abrasiveness, the production line adopts SBM-HPT Cone Crushers as the core crushing machines. After removing non-crushable magnetic metals, materials enter the "Crushing-Screening-Shaping" closed-loop system, significantly improving efficiency.

The entire production line adopts dry processing technology, operating in a fully enclosed system with zero wastewater discharge and minimal dust pollution, maximizing both production efficiency and environmental sustainability.

High-Quality Recycled Aggregates & High-Value Building Materials

SBM’s scientific, customized process design enables the project to annually produce:

· 1 million tons of premium recycled sand & aggregates

· 300,000 tons of dry-mixed mortar

· 150,000 m³ of green sponge city products

The line can also be extended to produce prefabricated construction elements and other recycled materials, catering to municipal, architectural, and sponge city applications.

A Win-Win for Ecology & Economy

· Saves land occupation and reduces solid waste pollution, delivering significant ecological benefits;

· Recycled aggregates replace natural sand and gravel, lowering construction material costs;

· Magnetic separation recovers metals like rebar and wires, generating additional revenue for clients.
