A jaw crusher is a primary crushing machine in rock and aggregate processing plants. Its design consists of a fixed jaw and a movable jaw, creating a V-shaped cavity where materials are crushed. The movable jaw exerts compressive force against the fixed jaw, breaking large rocks into smaller fragments. Key components include the frame, eccentric shaft, toggle plate, and flywheel.
| Parameter | Value |
|---|---|
| Feed Opening | 500x750mm to 1500x2100mm |
| Capacity | 50-800 TPH |
| Motor Power | 30-200 kW |
| Crusher Weight | 7-100 tons |
| Discharge Range | 20-300 mm (adjustable) |
A complete sand and aggregate production line typically includes:
1. Primary Jaw Crusher: Breaks large rocks into 150-300mm pieces.
2. Secondary Cone/Impact Crusher: Further reduces size to 20-50mm.
3. Vibrating Screen: Classifies materials by size (e.g., 0-5mm for sand).
Q: How to maintain jaw crushers?
A: Regularly check lubrication, tighten bolts, and replace worn liners/toggle plates.
Q: What’s the optimal feed size?
A: ≤80% of the crusher’s feed opening width to avoid jamming.
A granite quarry in Canada upgraded to a 500 TPH line featuring:
• Primary CJ612 Jaw Crusher (1200x1100mm feed)
• CH660 Cone Crusher (30mm discharge)
• SS3063 Screen (3-deck). Result: 25% energy savings and 0-5mm high-quality sand output.</
