Modern crushing and sand making production lines are designed to transform raw materials like granite, basalt, and limestone into high-quality aggregates for construction. Key equipment includes jaw crushers, cone crushers, impact crushers, and sand makers, each serving a specific role in the process.
1. Jaw Crusher: Primary crushing with a feed size up to 1,500mm and output adjustable to 10-350mm.
2. Cone Crusher: Secondary crushing for hard materials, producing 5-40mm aggregates with high cubicity.
3. Vertical Shaft Impact Crusher (Sand Maker): Produces 0-5mm artificial sand with a fineness modulus of 2.6-3.0.

| Equipment | Capacity (t/h) | Power (kW) |
|---|---|---|
| Jaw Crusher | 50-1,500 | 55-400 |
| Cone Crusher | 30-800 | 90-315 |
| Sand Maker | 20-500 | 110-400 |
Raw material → Primary crushing → Secondary crushing → Screening → Sand making → Washing → Finished aggregates (0-5mm, 5-10mm, 10-20mm).

Q: What is the lifespan of wear parts?
A: Jaw plates last 6-12 months; cone crusher mantles: 3-6 months; sand maker impellers: 4-8 months.
Q: How to reduce dust pollution?
A: Install dust covers and spray systems at transfer points.
A project in Vietnam processed 500t/h limestone using a jaw crusher (PE1200×1500), two cone crushers (HPT300), and a sand maker (VSI1140), achieving 95% utilization of raw materials with outputs of 0-5mm sand and 5
