Modern concrete crushing machines transform demolition waste into high-quality aggregates for construction. Key equipment includes jaw crushers (e.g., 90–450 kW power, 50–1,200 t/h capacity), impact crushers (for cubical-shaped output), and cone crushers (secondary/tertiary crushing). Mobile crushers like the ® LT1213™ combine mobility with 400 t/h throughput.
1. Primary Crushing: Jaw crusher (e.g., Feed size ≤1,200 mm, CSS 150–300 mm)
2. Secondary Crushing: Cone crusher (e.g., HP300 with 220 kW motor)
3. Screening: 3-deck vibratory screen (output: 0–5mm, 5–20mm, 20–40mm)
4. Sand Making: VSI crusher (50–500 t/h, producing ≤3mm manufactured sand)
| Equipment | Key Parameters |
|---|---|
| Jaw Crusher | Max feed: 1,500mm, CSS: 150–350mm |
| Cone Crusher | Closed-side setting: 6–38mm, Power: 75–315kW |
| VSI Crusher | Rotor speed: 1,500–2,500 rpm, Capacity: 60–650 t/h |
Q: What’s the lifespan of crusher wear parts?
A: Manganese jaws last ~200,000 tons in granite; reduce to 80,000 tons for abrasive concrete.
Q: How to control aggregate shape?
A: Use cone crushers with interparticle crushing or VSI for cubical aggregates.
