Technical Advantages and On-Site Performance
1. Capacity Achievement
The line is designed for a capacity of 100–150 tph. On-site data shows that when processing granite, the stable capacity remains between 120 and 140 tph, peaking at 150 tph (the design maximum). When processing basalt—which is harder—the capacity ranges from 100 to 120 tph, still meeting the design minimum.
2. Finished Product Shape
The PF1214 impact crusher produces excellent particle shapes, with a needle-and-flake content of ≤ 8% (well below the national standard limit of ≤ 15%). The finished aggregate is suitable for high-grade concrete (C30–C50) and asphalt mixtures without requiring additional shaping processes.
3. Wear Part Lifespan
| Component | Material | Expected Lifespan (Granite Application) |
| Jaw Plate | Mn18Cr2 High-Manganese Steel | 800–1,200 hours |
| Blow Bar | High-Chromium Cast Iron (Cr26) | 500–800 hours |
| Impact Liner | High-Manganese Steel | 1,200–1,500 hours |
4. Ease of Operation and Maintenance
• The jaw crusher features hydraulic discharge opening adjustment, allowing a single operator to adjust the gap within 5 minutes;
• The impact crusher is equipped with a hydraulic housing opening system, increasing blow bar replacement efficiency by 40%;
• The entire line utilizes centralized PLC control, requiring only two operators.
