Modern aggregate production relies on efficient crushing and grinding circuits to transform raw materials into high-quality sand and stone aggregates. These circuits typically consist of primary crushers, secondary/tertiary crushers, screens, and grinding mills, forming a complete processing line.
1. Jaw Crushers: Primary reduction of large rocks (Feed size: ≤1500mm, Capacity: 50-2000t/h)
2. Cone Crushers: Secondary/Tertiary crushing (Closed-side setting: 6-38mm)
3. Impact Crushers: For shaping aggregates (Product cubicity ≥90%)
4. Vibrating Screens: Material classification (Screen decks: 1-4 layers)
5. Ball Mills/Vertical Mills: Fine grinding (Fineness: 80-325 mesh)
| Equipment | Model | Power(kW) | Capacity(t/h) |
|---|---|---|---|
| Jaw Crusher | C6X160 | 160-250 | 300-800 |
| Cone Crusher | HPT300 | 315 | 120-440 |
| VSI Crusher | S8-1145DR | (2×)315kW | 200-500 |
| Trommel Screen | TTS620 | 45 | 400 |
Q:What’s the difference between open-circuit and closed-circuit grinding?
A:Open-circuit processes material once while closed-circuit recycles oversize material through classifiers.
Q:How to choose between jaw crusher and gyratory crusher?
A:Jaw crushers suit smaller operations (1000t/h).
