Q: What is the service life of the roller skins?

The durability of the roller skins is the most critical factor for operational cost. Generally, our rollers last between 6 months and 2 years. The exact lifespan depends on the following factors:

• Material Abrasiveness: Hard ores like quartz or granite wear the surface faster than coal.
• Feeding Consistency: Even distribution across the roller prevents uneven “groove” wear.
• Moisture Levels: Excessive wetness can cause material slippage and accelerated abrasion.
• Operational Pressure: Higher hydraulic pressure for fine crushing increases mechanical stress.

💡 Engineering Tip:
Our rollers use High-Chromium Manganese Alloy. Unlike standard skins, these can be surface-welded and repaired on-site, which can extend the total service life by 30-50% without a full replacement.
