Underground mining demands robust and efficient equipment to handle hard rock crushing and sand production. Hydraulic-powered machines excel in confined spaces, offering high power density and precise control. Key equipment includes hydraulic jaw crushers, cone crushers, and vertical shaft impactors (VSI) for shaping aggregates.

| Equipment | Model | Power (kW) | Capacity (t/h) | Feed Size (mm) |
|---|---|---|---|---|
| Hydraulic Jaw Crusher | UJC-450 | 132 | 150-380 | ≤650 |
| Tunnel Cone Crusher | TCC-300H | 250 | 200-450 | ≤250 |
| Mining VSI Crusher | MVSI-900 | 315 | 120-350 | ≤50 |
| Screening Plant (Modular) | SMP-3D2160 | 37×3 | 400-600 | N/A |
Compact dimensions with foldable conveyors enable easy transport through mine shafts. All components feature dust-proof seals and explosion-proof electrical systems compliant with ATEX standards. The hydraulic system operates at 350 bar pressure with automatic overload protection.
