Gyratory crushers are primarily used in the mining and aggregate industries for primary crushing of hard, abrasive materials. These robust machines excel in high-capacity operations, processing large feed sizes (up to 1500mm) with throughput exceeding 10,000 metric tons per hour.
A complete crushing-sand making plant typically includes:
1. Primary crushing: Gyratory crusher (e.g., CG850i with 500kW motor)
2. Secondary crushing: Cone crusher
3. Tertiary crushing: Vertical shaft impactor (VSI)
4. Screening equipment
5. Material handling systems
| Model | Feed Opening | Capacity (tph) | Power (kW) |
|---|---|---|---|
| CG650i | 630mm | 3,500-12,000 | 525 |
| CG810i | 790mm | 5,000-15,000 | 660 |
| CG850i | 1,067mm | 6,000-18,000 | 895 |
– Continuous crushing action increases efficiency
– Higher capacity-to-size ratio than jaw crushers
– Longer wear part life (mantles last 6-12 months)
– Ability to handle slabby materials without bridging

Q: What’s the maintenance interval?
A: Major inspections every 10,000 hours; lubrication system checks weekly.
Q: Can it process wet material?
A: Yes, but capacity reduces by 15-20% compared to dry processing.
Q: What’s the typical reduction ratio?
A: 6:1 to 8:1 for primary crushing applications.
