A crushing and sand-making production line is essential for processing raw materials like granite, limestone, and basalt into high-quality aggregates. The core equipment includes jaw crushers, cone crushers, impact crushers, sand makers, vibrating screens, and conveyors.
1. Primary Crushing: Jaw Crusher (e.g., Feed size: ≤1200mm, Capacity: 50-1500t/h)
2. Secondary Crushing: Cone Crusher (e.g., Max feed size: ≤300mm, Output: 40-600t/h)
3. Tertiary Crushing: Vertical Shaft Impact Crusher (e.g., Capacity: 60-520t/h, Finished product shape: Cubic)
4. Screening: Vibrating Screen (e.g., Layers: 1-4, Mesh size: 3-100mm)
| Equipment | Model Example | Feed Size (mm) | Capacity (t/h) | Power (kW) |
|——————–|—————|—————-|—————-|————|
| Jaw Crusher | PE750×1060 | ≤630 | 110-250 | 110 |
| Cone Crusher | HPT300 | ≤240 | 90-360 | 315 |
| Sand Maker | VSI6X1150 | ≤50 | 200-520 | 440 |
Q1: How to reduce dust in the production line?
A: Use dust collectors and water spray systems at transfer points.
Q2: What’s the lifespan of wear parts?
A: Typically 3-6 months for jaw plates and 6-12 months for cone crusher mantles, depending on material hardness.
A granite processing plant in Vietnam adopted a 500t/h production line with PE1200×1500 jaw crusher + HST315 cone crusher + VSI6X1263 sand maker. The final products met ISO standards for construction aggregates with <5% needle content.
