Modern rock grinding machines are engineered to transform raw stones into high-quality sand and powder for construction aggregates. These systems integrate crushing, grinding, and screening technologies to meet precise particle size requirements.
1. Primary Jaw Crusher: Handles large rocks (≤1200mm) with 50-500TPH capacity
2. Cone Crusher: Secondary reduction with hydraulic adjustment (≤300mm output)
3. Vertical Shaft Impact Crusher: Produces cubic-shaped sand particles
4. Ball Mill/Raymond Mill: For ultra-fine powder production (80-400 mesh)
| Model | Max Feed Size | Output Size | Capacity (TPH) |
|---|---|---|---|
| JCE1302 | 1200mm | 150-300mm | 500-800 |
| HPT300 | 350mm | 30-60mm | 200-350 |
| VSI1140 | 50mm | 0-5mm sand | 100-180 |
Raw material → Primary crushing → Secondary crushing → Sand making → Screening → Powder grinding → Finished product storage
Q: What’s the power consumption per ton?
A: Typically 15-30kWh/ton depending on material hardness.
Q: How to control powder fineness?
A: Adjust classifier speed or grinding pressure in mill systems.
Q: Dust control solutions?
A: Pulse bag filters achieve 99.9% collection efficiency.
