For small-scale marble mining operations, the average cost of essential equipment ranges from $50,000 to $200,000, depending on capacity and automation levels. Key machinery includes jaw crushers, hammer crushers, vibrating screens, and conveyors.
A compact marble processing line typically consists of:
1. Primary Jaw Crusher: Processes raw marble blocks (≤650mm) into 100-200mm fragments. Model example: PE-400×600 (Capacity: 16-64t/h, Power: 30kW).
2. Secondary Impact/Hammer Crusher: Further reduces material to ≤30mm. Model: PCΦ800×600 (Capacity: 18-25t/h, Power: 55kW).
3. Vibrating Screen: Separates aggregates into 0-5mm (sand), 5-10mm, and 10-30mm grades. Model: 3YK1548 (Processing capacity: 50-150t/h).
| Equipment | Model | Capacity (t/h) | Power (kW) | Feed Size (mm) |
|——————–|————-|—————-|————|—————-|
| Jaw Crusher | PE-400×600 | 16-64 | 30 | ≤340 |
| Hammer Crusher | PCΦ800×600 | 18-25 | 55 | ≤200 |
| Vibrating Screen | 3YK1548 | 50-150 | 15 | ≤400 |
Q1: What’s the lifespan of these machines?
A1: With proper maintenance, jaw crushers last 5-8 years; hammer crushers ~5 years due to wear parts.
Q2: Can this setup produce graded sand for concrete?
A2: Yes, by adjusting screen meshes and adding a sand washer (optional), it meets ASTM C33 standards.
Project: A Peruvian marble quarry upgraded to a 50t/h line using PE-400×600 + PCΦ800×600 + 3YK1548.
