Marble mining requires significant capital investment, particularly for setting up efficient crushing and sand-making production lines. The process involves primary crushing, secondary shaping, and fine sand production to transform raw marble into high-quality aggregates.
1. Jaw Crusher: Primary crushing with 500-800mm feed size capacity
2. Cone Crusher: Secondary crushing producing 20-50mm particles
3. Vertical Shaft Impact (VSI) Crusher: Final shaping for 0-5mm sand
| Equipment | Model Example | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-160 | 75 |
| Cone Crusher | HPT300 | 120-340 | 315 |
| VSI Crusher | S8-1145 | 100-260 | 250×2 |
| Screening Machine | 3YK3070 | >500t/h processing capacity |
Q: What’s the minimum viable production capacity?
A: For commercial operations, 100t/h is typically the entry-level capacity requiring ~$500k initial investment.
Q: How to control dust pollution?
A: Modern plants use water spray systems + bag filters with >99% efficiency.
Location: Dodoma Region
Configuration: PE750×1060 Jaw + HST315 Cone + 3 sets VSI1145
Output: 280t/h finished aggregates
Application: Local road construction and concrete batching plants
The complete line achieved ROI within 18 months through optimized particle gradation meeting ASTM C33 standards for construction aggregates. Proper equipment selection reduced power consumption by 22% compared to traditional setups.
