Common FAQs

1. What is the recommended lubrication schedule for the CH880 crusher?
   The manual specifies oil changes every 1,000 operating hours or every six months, whichever comes first. Regular inspection of oil quality is also advised.

2. How often should wear parts like mantles and concaves be replaced?
   Depending on material hardness, mantles typically last 6–12 months, while concaves may last longer (up to 18 months). Monitoring wear patterns helps optimize replacement timing.

3. Can the CH880 handle abrasive materials like granite or basalt?
   Yes, but with increased wear. Using high-quality manganese steel liners and reducing feed size can extend component life in abrasive conditions.

4. What safety precautions are critical during maintenance?
   Always lock out power before servicing, use proper lifting equipment for heavy parts, and follow Sandvik’s guidelines for hydraulic system depressurization.

5. How does the ASRi™ automation system improve performance?
   The Automatic Setting Regulation (ASRi™) adjusts the crusher’s closed-side setting in real time to optimize throughput and reduce manual intervention.

Real-World Application: Mining Case Study

A copper mine in Chile implemented the CH880 crusher to replace an older model struggling with frequent downtime. After installation:

• Throughput increased by 20% due to optimized crushing settings via ASRi™.
• Maintenance costs dropped by 15% thanks to longer-lasting wear parts and predictive maintenance alerts from onboard sensors.
• The mine reported a 30% reduction in unplanned stoppages, attributed to improved lubrication monitoring and automated fault detection.
