Optimizing Rebar Recycling: LIDI Shredding System for Steel Recovery

1. Material Specifications

Structural Properties

Composition: Carbon steel (0.25-0.29% C content)

Standard lengths: 6-12m (as-supplied), 1-3m (post-demolition)

Common contaminants:

Concrete encrustation (5-20mm thickness)

Epoxy coatings (in corrosion-resistant rebar)

2. Processing Challenges

Operational Constraints

High wear on cutting tools (3x faster than auto shredding)

Tangling risk in conventional single-shaft systems

Spark generation during processing

3. System Configuration

LIDI Shredder Technical Parameters

Rotational speed: 18-22 RPM (variable frequency drive)

Hydraulic system: 350 bar pressure rating

Feed opening: 1500×2000mm (W×H)

Ancillary Equipment

Vibratory feeder with metal detection

Post-shredder magnetic separation tunnel
