A complete crushing and sand-making production line for aggregates typically includes primary crushers, secondary crushers, sand-making machines, vibrating screens, and conveyors. Key equipment:
1. Jaw Crusher (Primary Crushing)
– Capacity: 50–1,500 t/h
– Feed Size: ≤1,200 mm
– Output Size: 10–350 mm
2. Cone Crusher (Secondary Crushing)
– Capacity: 30–800 t/h
– Closed Side Setting (CSS): 6–38 mm
3. Vertical Shaft Impact Crusher (Sand Making)
– Capacity: 60–520 t/h
– Output: 0–5 mm (adjustable)
4. Vibrating Screen
– Layers: 1–4
– Screening Efficiency: ≥90%
Raw materials (e.g., granite, basalt) are fed into the jaw crusher for coarse crushing. Secondary crushing by cone crushers refines the material. The VSI crusher then shapes particles into high-quality sand. Screens classify outputs into sizes like 0–5mm (sand), 5–10mm, or 10–20mm (gravel).
| Equipment | Model Example | Max Feed Size | Output Size Range | Power (kW) |
|——————–|—————|—————|——————-|————|
| Jaw Crusher | PE1200×1500 | 1,020 mm | 150–300 mm | 160–220 |
| Cone Crusher | HPT300 | 240 mm | 6–30 mm | 250 |
| VSI Crusher | B9100SE | 50 mm | 0–5 mm | 400 |
Q: How to reduce dust in the production line?
A: Install dust collectors or water spray systems at transfer points.
Q: What’s the lifespan of wear parts in a VSI crusher?
A: Rotor tips last ~200 hours for abrasive materials; anvils up to 600 hours.
