single roll crusher capacity for gold ore

The capacity of a single roll crusher for gold ore depends on several factors, including:

1. Roll Diameter & Width – Larger rolls handle higher throughput.
2. Ore Characteristics – Hardness, moisture content, feed size distribution, and abrasiveness affect capacity.
3. Gap Setting – The distance between the roll and the crushing plate determines product size and throughput.
4. Roll Speed – Higher RPM increases capacity but may reduce fines generation.
5. Feed Size (F80) – Larger feed sizes reduce capacity compared to finer feeds.

Estimated Capacity Range for Gold Ore Crushing:

• Small-scale single roll crushers (~300–600 mm diameter): 5–30 TPH (tonnes per hour).
• Medium-sized (~600–900 mm diameter): 30–100 TPH.
• Large industrial units (>900 mm diameter): 100–300+ TPH.



Key Considerations:

• Gold ores are often abrasive and may contain hard quartz, requiring durable roll surfaces (e.g., manganese steel).
• Moisture content should be <10% to prevent clogging (sticky ores may need pre-screening).
• Closed-circuit crushing improves efficiency by recycling oversized material.

For precise sizing, consult manufacturers like Metso, FLSmidth, or Sandvik, providing:

• Ore hardness (Bond Work Index, UCS),
• Desired product size (P80),
• Feed size distribution (F80).
