Construction waste recycling

Track-mounted jaw, impact and screen turn construction and demolition waste into recycled aggregate, on the site itself or at the recycling plant.

Construction waste moves from site to site and mixes concrete, masonry, asphalt and rebar. That is why Leimeng recommends mobile sets: a jaw crusher for the primary, an impact crusher for the secondary with a magnetic separator, and a track-mounted screen for classification.

The impact crusher is the heart of recycling: it accepts mixed material, delivers cubic particles and has a high reduction ratio, with lower investment than a cone.

A stationary recycling plant, where volume is constant, uses the same equipment on skids or on foundations.

Selection criteria

What defines the layout

HeterogeneityImpact crushing tolerates mixed material; a cone is not suited to C&D waste.
RebarMagnetic separator required ahead of the secondary.
MobilityThe face changes with every project; tracks and hybrid drive avoid dismantling.
StandardRecycled aggregate for concrete and pavement follows Brazilian standard NBR 15116; classification defines the use.

Line complements

Indicative pre-selection from the tables published by Leimeng. Final sizing considers work index, moisture, feed size, product curve and utilisation factor. An application engineer validates the layout before the proposal.
