Every year, billions of tons of construction and demolition (C&D) waste are generated globally. Simply landfilling it wastes precious space, resources, and harms the environment. So, how can we transform this discarded concrete and rubble into a valuable resource? The answer lies in an efficient C&D waste crushing and screening plant.

The Core Solution: Mobile Crushing and Screening Stations

For scattered demolition sites, mobile crushing and screening stations are the ideal choice. They can be driven directly to the site, processing waste on the spot and eliminating high transport costs.

1. Pre-Sorting and Feeding: Wood, plastic, and other impurities are removed via manual or mechanical sorting. The remaining concrete blocks are evenly fed into the crusher by a feeder.

2. The Core Crushing Stage: A jaw crusher is typically used for primary crushing, breaking down large concrete chunks. Next, an impact crusher or cone crusher handles secondary crushing. Impact crushers produce well-shaped aggregate, ideal for road base materials. For higher demands on particle shape and hardness, a cone crusher is preferred.

3. De-ironing and Screening: A magnetic separator removes rebar during crushing. Subsequently, a vibrating screen classifies the material into different specifications (e.g., 0-5mm, 5-10mm, 10-31.5mm), producing clean recycled coarse and fine aggregate.

4. Final Application: This recycled aggregate can be used for road sub-bases, backfill, producing recycled bricks, concrete blocks, and even in some non-structural concrete, closing the resource loop.

The Investment Value: It not only solves waste disposal problems but also creates a new revenue stream, helps companies obtain green building certifications, and enhances their social responsibility profile.
