For coal mining operations complying with MSHA (Mine Safety and Health Administration) standards in New Mexico, integrating a high-efficiency sandstone crushing and screening line is critical for producing quality aggregates. This setup ensures optimal resource utilization while meeting safety regulations.
The primary components include:
1. Jaw Crusher: Primary reduction (e.g., PE600×900, capacity 50-160t/h)
2. Cone Crusher: Secondary crushing (e.g., HPT300, max feed size 240mm)
3. VSI Crusher: Shaping (e.g., B9100SE, throughput up to 350tph)
4. Vibrating Screens: Multi-layer classification (e.g., 3YK3070, screening area 7.5m²)
| Equipment | Key Parameters |
|---|---|
| Jaw Crusher | Feed opening: 600×900mm, Power: 75kW |
| Cone Crusher | Closed-side setting: 13-51mm, Capacity: 120-400tph |
| VSI Crusher | Rotor speed: 1200-1800rpm, Max feed size: 65mm |
| Screening System | Screen mesh: 3-100mm layers, Inclination: 15-20° |
A coal mine in Farmington upgraded their aggregate production with:
– Throughput: 250tph of ASTM C33 compliant sand
– Final products: 0-5mm (40%), 5-20mm (35%), 20-40mm (25%)
– Dust control achieved through mist cannons and enclosed conveyors
Q1: How does MSHA affect equipment selection?
A: Requires explosion-proof motors and dust suppression systems on all units.
Q2: Typical
