Alpine Stone Grinding Industries: Revolutionizing Aggregate Processing
Alpine Stone Grinding Industries specializes in high-performance crushing, grinding, and screening solutions tailored for the aggregate and mining sectors. Our advanced equipment ensures optimal particle shape, gradation control, and energy efficiency—critical factors for modern sand and gravel production.
Our flagship products include jaw crushers, cone crushers, vertical shaft impactors (VSIs), and grinding mills designed for hard rock and abrasive materials. Below are key specifications:
| Model | Capacity (TPH) | Max Feed Size (mm) | Power (kW) | Application |
|—————–|——————–|————————|—————-|——————————|
| ASGI-JC120 | 150-350 | 750 | 132 | Primary crushing |
| ASGI-VSI800 | 200-500 | 50 | 315 | Sand shaping |
| ASGI-GM4000 | 30-100 | 25 | 160 | Fine grinding |

A typical Alpine-designed sand-making line integrates:
1. Primary Crushing: ASGI-JC120 jaw crusher reduces raw stone to ≤150mm.
2. Secondary Screening: Multi-deck vibratory screens segregate oversized material for recirculation.
3. Tertiary Shaping: ASGI-VSI800 optimizes particle roundness (<5% flakiness index).
4. Grinding & Classification: Closed-circuit mills with air classifiers produce ultra-fine fillers (0-0.6mm).
