The Cedar Rapids jaw crusher is a robust primary crushing solution for aggregate production. Known for its durability and high throughput, it’s widely used in sand, gravel, and hard rock processing. Regular maintenance, guided by the service manual, ensures optimal performance and longevity.
| Model | Feed Opening (in) | Capacity (TPH) | Power (HP) |
|---|---|---|---|
| 3042 | 30×42 | 150-250 | 150 |
| 3055 | 30×55 | 200-400 | 250 |
| 3648 | 36×48 | 300-500 | 300 |
A typical sand/gravel production line combines Cedar Rapids crushers with vibrating screens (e.g., 6×20 triple deck), cone crushers for secondary crushing, and conveyors. Proper alignment reduces wear and boosts output by 15-20%.
– Q: Excessive vibration? A: Check unbalanced flywheels or worn bearings.
– Q: Low output? A: Verify jaw plate wear (replace if gap exceeds 10%).
– Q: Overheating bearings? A: Inspect lubrication (use ISO 150+ grease).
A Missouri quarry increased uptime by 30% after adopting Cedar Rapids 3055 with scheduled lubrication (per manual) and pairing it with a MVP380X cone crusher. Annual production reached 1.2M tons of ASTM C33-spec aggregates.
