stone crusher capacity rocks mined quarry

A stone crusher’s capacity in a quarry depends on several factors, including the type of crusher, rock hardness, feed size, and desired output size. Here’s a breakdown of key considerations:

1. Types of Stone Crushers & Their Capacities

• Jaw Crusher: 50–1,600 tons/hour (for hard rocks like granite)
• Cone Crusher: 100–1,200 tons/hour (for medium-hard to hard rocks)
• Impact Crusher: 50–500 tons/hour (for softer rocks like limestone)
• Gyratory Crusher: 500–6,000 tons/hour (large quarries)



2. Factors Affecting Crusher Capacity

• Rock Hardness (e.g., granite vs. limestone)
• Feed Size (larger rocks reduce capacity)
• Crusher Settings (closed-side setting affects output size & throughput)
• Moisture Content (wet material may clog crushers)



3. Quarry Production Considerations

• A typical quarry produces 200–10,000 tons/day, depending on scale.
• Blasted rock is first reduced by a primary crusher (jaw/gyratory), then secondary/tertiary crushers refine the size.

4. Calculating Required Crusher Capacity

If a quarry mines 500 tons/hour, the crusher must handle at least that rate after accounting for:
– Downtime (maintenance, feeding delays)
– Rock variability

Example Calculation:

• Target production: 500 tph
• Efficiency factor: ~80% (due to operational delays)
• Required crusher capacity = \( \frac{500}{0.8} = 625 \, \text{tph} \)

5. Matching Crushers to Quarry Needs

| Rock Type | Recommended Crusher | Typical Capacity |
|———–|——————–|——————|
| Granite | Jaw + Cone | 300–800 tph |
| Limestone | Impact/Jaw | 200–600 tph |
| Basalt | Gyratory + Cone | 500–1,500 tph |

Conclusion

To choose the right stone crusher for your quarry:
1. Determine daily production needs.
2. Test rock hardness & feed size.
3. Select a crusher with ~20% extra capacity for efficiency losses.
