The crystal stone crusher grinder is a critical piece of equipment in modern aggregate processing lines, designed to transform raw crystalline rocks (e.g., quartz, granite) into high-quality sand and crushed stone for construction and industrial applications. This article delves into the technical specifics, production line integration, and real-world applications of these machines.
Crystal stone crusher grinders combine impact, compression, and attrition principles to achieve precise particle size reduction. Key variants include:
1. Jaw Crushers (Primary Crushing)
– Feed Size: ≤1,200mm
– Capacity: 50-1,500 t/h
– Power: 55-400 kW
2. Cone Crushers (Secondary/Tertiary)
– Closed-side Setting: 6-38mm
– Throughput: 45-1,000 t/h
– Hydraulic Adjustment: ±10% CSS
3. Vertical Shaft Impactors (VSI Grinders)
– Rotor Speed: 1,500-3,000 rpm
– Product Shape: Cubical (>90%)
– Moisture Tolerance: ≤5%
| Model | Max Feed (mm) | Output Size (mm) | Motor Power (kW) |
|---|---|---|---|
| CS-J160 | 800 | 0-40 adjustable | 132 |
| CS-VSI85 | 50 | 0-8 (sand mode) | 315 |
| CS-HP300 | 230 | 10-25 | 250 |
Optimal configuration for crystalline materials requires:
– Pre-screening: Remove fines (<5mm) before primary crushing to reduce wear
– Multi-stage crushing: Typically 3 stages for producing 0-5mm sand and 5-20mm aggregate
– Air Classification: Essential for high-purity quartz processing (SiO₂ >99%)
