A complete rock crushing and sand-making production line typically includes primary crushers, secondary/tertiary crushers, vibrating screens, and sand washers. The core equipment—jaw crushers, cone crushers, and impact pulverizers—are engineered to process hard ores (e.g., granite, basalt) with feed sizes up to 1,500mm and output 0-40mm aggregates.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-160 | 75 |
| Cone Crusher | HPT-200 | 90-250 | 160 |
| Impact Pulverizer | PF-1315 | 100-280 | 220 |
| Vibrating Screen | 3YK-2160 | 80-500 | 30 |
Q1: How to reduce dust in crushing plants?
A: Install water spray systems or pulse bag filters at transfer points.
Q2: What’s the lifespan of crusher wear parts?
A: Manganese steel jaws/cones last 3-6 months under medium-hard ore conditions.
A 200tph line deployed a PE750×1060 jaw crusher + HST315 cone crusher + VSI1140 sand maker, achieving 45% crushed sand yield with ＜5% needle content. Maintenance cycles were extended by 40% using automated lubrication systems.
The latest electric-driven crushers reduce CO₂ emissions by 15% compared to diesel models. Noise levels are controlled below 75dB with soundproof encl
