The jaw capacity of a crusher refers to the maximum volume or throughput of material that a jaw crusher can process, typically measured in tons per hour (TPH) or cubic meters per hour (m³/h). It depends on several factors, including:

Key Factors Affecting Jaw Crusher Capacity:
1. Feed Opening Size – Width and depth of the crushing chamber (e.g., 900×600 mm).
2. Closed Side Setting (CSS) – The smallest gap between the jaws, affecting output size and capacity.
3. Material Hardness & Density – Softer materials (e.g., limestone) allow higher throughput than harder rocks (e.g., granite).
4. Feed Size & Gradation – Larger or irregularly sized feed reduces efficiency.
5. Crusher Speed & Stroke – Faster eccentric shaft movement can increase capacity but may affect product shape.
6. Moisture & Stickiness – Wet or sticky materials may clog the crusher, reducing throughput.
Typical Jaw Crusher Capacities (Estimate)
| Model (Feed Opening) | CSS Range | Capacity (TPH) |
|———————-|———-|—————|
| 250×400 mm | 20–80 mm | 5–20 TPH |
| 600×900 mm | 50–175 mm| 50–180 TPH |
| 900×1200 mm | 75–200 mm| 150–350 TPH |.jpg)
1200×1500 mm | 100–250 mm| 300–650 TPH |
Maximizing Jaw Crusher Capacity:
– Optimize feed size distribution (pre-screening helps).
– Maintain proper CSS for desired output.
– Ensure even feeding to avoid uneven wear.
– Use a vibrating feeder for consistent material flow.
