The puzzle stone recycling machine is a cutting-edge solution for transforming construction waste into high-quality sand and aggregates. This equipment integrates crushing, screening, and shaping functions to process hard rocks (granite, basalt) and demolition concrete into 0-5mm manufactured sand and 5-40mm coarse aggregates.
| Model | Capacity (t/h) | Power (kW) | Max Feed Size (mm) |
|---|---|---|---|
| PSR-750 | 50-80 | 132 | 350 |
| PSR-1060 | 120-180 | 220 | 500 |
| PSR-1315 | 200-280 | 315 | 650 |
A complete puzzle stone recycling system typically includes:
1. Vibrating feeder with pre-screening
2. Jaw crusher for primary reduction
3. Impact crusher or cone crusher for secondary crushing
4. VSI sand maker for cubical shaping
5. Multi-layer vibrating screen
6. Sand washing system
Q: What’s the final product application?
A: The output meets ASTM C33 standards for concrete production, road bases, and precast elements.
Q: How to control dust emission?
A: Our system features water spray nozzles and pulse bag filters with ≤20mg/m³ emission.
A 200t/h recycling plant processed demolished concrete from old buildings to produce:
– 45% 0-4.75mm fine aggregate for new concrete mixing
– 35% 5-20mm coarse aggregate for pavement base
– 20% oversize materials recycled back to crusher
The operation achieved 95% material utilization rate with ROI within 18 months.
