Granite crushing and sand-making production lines require robust machinery to handle this hard, abrasive material. A gradient machine system typically includes jaw crushers for primary crushing, cone crushers for secondary reduction, and vertical shaft impact (VSI) crushers for shaping aggregates.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Primary Jaw Crusher | PE750×1060 | 110-250 | 110 |
| Hydraulic Cone Crusher | HPT300 | 120-350 | 315 |
| VSI Sand Maker | S8-1145 | 150-380 | 400×2 |
| Tertiary Impact Crusher | TIC-1220 | 200-450 | 315×2 |
1. Primary crushing reduces 800mm granite blocks to ≤200mm
2. Secondary cone crushing produces 40-70mm aggregates
3. Tertiary shaping creates 0-5mm manufactured sand
4. Air screening separates products into required gradations
Q: What’s the wear life of crusher parts?
A: Manganese steel jaws last 3-6 months; tungsten carbide tips in VSI last 80-120 hours.
Q: How to control dust pollution?
A: Recommended solutions include:
• Water spray systems at transfer points
• Pulse bag dust collectors
• Enclosed conveyor galleries
Q: What final products can be obtained?
A: Typical outputs:
• 0-5mm artificial sand (≤15% needle content)
• 5-10mm aggregate
• 10-20mm aggregate
• 20-31.5mm coarse aggregate
