How do mobile crushers process construction waste?

Construction waste—concrete, bricks, mortar, and mixed debris—can be efficiently recycled into high-quality aggregate with mobile crushing plants. As a leading provider of crushing and screening solutions, Shanghai Dongmeng designs mobile crushers that turn demolition waste into valuable building materials on-site, supporting circular economy and green construction.

Step 1: On-site feeding & pre‑sorting

Waste is loaded into a vibrating grizzly feeder, which screens out fine soil and small debris upfront. An integrated magnetic separator automatically extracts steel bars and metal, protecting the crusher and recovering valuable scrap.

Step 2: Primary crushing

Dongmeng’s mobile jaw crusher takes large concrete blocks and rubble, crushing them down to 100–150 mm via high‑pressure extrusion. Its robust design handles mixed waste with ease, serving as the core of the primary stage.

Step 3: Secondary crushing & shaping

For finer, well‑shaped aggregate, material moves to a mobile impact or cone crusher. This step refines particles to 0–31.5 mm and improves grain shape, making recycled aggregate suitable for concrete, road base, and brick production.

Step 4: Screening & classification

A mobile screening plant divides material into graded sizes (0–5 mm, 5–10 mm, 10–20 mm, 20–31.5 mm). Oversized material is recirculated for re‑crushing, ensuring full utilization.

Step 5: Cleanup & final output

Optional air separation removes light impurities (plastic, wood), producing clean, high‑purity recycled aggregate that meets national standards.

Why choose Shanghai Dongmeng mobile crushers?
