A complete crushing and sand-making production line is designed to transform raw materials (e.g., granite, basalt, limestone) into high-quality aggregates and manufactured sand. Key machines include:
1. Jaw Crusher – Primary crushing with a feed size of up to 1,500mm and output adjustable from 50–300mm.
2. Cone Crusher – Secondary crushing for medium-hard materials, producing 20–70mm output.
3. Vertical Shaft Impact Crusher (VSI) – Core sand-making equipment, yielding 0–5mm fine sand with high sphericity.
4. Vibrating Screen – Multi-layer screening for precise grading (e.g., 0–5mm, 5–10mm, 10–20mm).

| Equipment | Model Example | Capacity (t/h) | Power (kW) | Output Size (mm) |
|——————–|—————|—————-|————|——————|
| Jaw Crusher | PE-600×900 | 50–160 | 75 | 65–160 |
| Cone Crusher | HPT-300 | 100–350 | 315 | 10–40 |
| VSI Crusher | B-9100 | 150–350 | 400 | 0–5 |

Q: What’s the lifespan of wear parts in a VSI crusher?
A: Tungsten carbide tips typically last 80–120 hours for abrasive materials like granite.
Q: How to reduce dust in the production line?
A: Install water spray systems or pulse dust collectors at transfer points.
A granite processing plant in Vietnam adopted a 200tph line with jaw + cone + VSI configuration. Final products met ASTM C33 standards for concrete aggregates, achieving <5% needle content in sand.
