A concrete recycling machine is a specialized piece of equipment designed to crush and repurpose old concrete roads into reusable materials. Here are some common types of machines used for this purpose:
1. Mobile Jaw Crusher
– Function: Breaks down large chunks of old concrete into smaller pieces.
– Output: Produces coarse aggregate that can be reused in new construction.
– Advantage: Portable, can be moved to different job sites.
2. Impact Crusher
– Function: Uses high-speed impact to crush concrete into finer material.
– Output: Produces well-shaped aggregate suitable for road base or drainage layers.
Best For: Recycling reinforced concrete (removes rebar efficiently).
3. Concrete Pulverizer (Attached to Excavator)
– Function: Crushes and separates concrete from rebar or other metals.
– Use Case: Ideal for demolition sites where old road slabs need processing.
4. Screening Plant
– Function: Sorts crushed concrete into different sizes (e.g., gravel, sand).
– Output: Clean, graded material for reuse in new asphalt or concrete mixes.
5. Road Reclaimer/Soil Stabilizer
– Function: Grinds old asphalt/concrete roads in place and mixes them with binding agents (like cement or lime) to create a new base layer.
– Use Case: Full-depth reclamation (FDR) for road rehabilitation.
Benefits of Recycling Old Roads:
– Reduces landfill waste.
– Lowers costs compared to new materials.
– Sustainable construction practice (LEED credits).
