Chamarajanagar, Karnataka, is renowned for its premium black granite deposits. To process this hard rock efficiently, a well-designed crushing and sand-making production line is essential. Here’s a breakdown of the optimal equipment configuration:
1. Primary Jaw Crusher
– Model: JC120
– Feed Size: ≤650mm
– Capacity: 150-300 TPH
– Power: 132kW
2. Secondary Cone Crusher
– Model: HPC300
– Max Feed: 240mm
– Output: 30-50mm (adjustable)
– Power: 220kW
3. Tertiary Impact Crusher (for shaping)
– Model: VSI6X1150
– Throughput: 200-400 TPH
– Finished Sand: 0-5mm (cube-shaped)
4. Screening System
– Multi-deck Vibrating Screens (3YK3070)
| Equipment | Output Size | Capacity (TPH) |
|---|---|---|
| Jaw Crusher | ≤150mm | 150-300 |
| Cone Crusher | 30-50mm | 200-350 |
| VSI Crusher | 0-5mm sand | 200-400 |
