Mining Bond Work Index: crusher_performance
Bond work index (Wi, kWh/ton) for 29 mineral and ore types, crusher performance parameters (jaw, gyratory, cone, HSI, VSI, roll, HPGR), and grinding mill design parameters (ball, SAG, AG, rod, vertical roller).

| parameter type | record id | Bond work index kWh per ton (kWh/ton) | Mohs hardness (dimensionless) | abrasion index Ai (dimensionless) | capacity tph per ft width (tph) | crusher type | feed size max mm (mm) | mineral or ore | notes | product size P80 mm (mm) | reduction ratio (dimensionless) | specific gravity (dimensionless) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| crusher_performance | Copper ore|gyratory | 14 | 3 | 0.3 | 300 | gyratory | 1,200 | Copper ore | Gyratory typical for large porphyry copper mines; reduction 3:1-10:1; compressive strength up to 600 MPa capacity | 200 | 6 | 3.02 |
| crusher_performance | Hard rock (granite/basalt)|jaw | 17.5 | 6.5 | 0.48 | 80 | jaw | 1,000 | Hard rock (granite/basalt) | Primary jaw: max feed 0.85 × gape; reduction ratio 4:1-7:1; capacity ≈ (width in inches) × 10 tph rough rule | 180 | 6 | 2.78 |
| crusher_performance | Iron ore (HPGR application)|HPGR | 16.1 | 5.5 | 0.55 | 600 | HPGR | 50 | Iron ore (HPGR application) | High-pressure grinding roll (HPGR/Polycom); pre-crush for SAG-ball circuit; micro-cracking reduces downstream Wi 10-20% | 5 | 10 | 3.88 |
