Shell liners, Lifter bars
Shell Liner (Lifter Bar + Plate)
Protects SAG mill shell and provides lifting action for grinding charge; optimized lifter height and spacing for maximum grinding efficiency
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Cr-Mo Alloy Steel | 0.15-0.25 | 0.30-0.60 | 0.50-0.80 | 1.00-1.50 | 0.45-0.65 | — |
Good combination of hardness and toughness; ideal for SAG mill liners, grate bars and crusher frame liners under abrasive wear
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Cr26 | 2.0-3.3 | ≤1.0 | 0.5-1.5 | 23.0-30.0 | 1.0-3.0 | ≤1.5 |
Excellent abrasion resistance with M7C3 carbide network; 3-5x longer life than Mn steel in pure abrasive wear; ideal for vertical mill rollers and VSI rotors
Grate Plate (Discharge)
Controls discharge size while retaining grinding media; pebble port design for autogenous grinding circuits
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Cr26 | 2.0-3.3 | ≤1.0 | 0.5-1.5 | 23.0-30.0 | 1.0-3.0 | ≤1.5 |
Excellent abrasion resistance with M7C3 carbide network; 3-5x longer life than Mn steel in pure abrasive wear; ideal for vertical mill rollers and VSI rotors
Grate Panel
SAG mill discharge grate; retains grinding balls while allowing pulp to exit
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| Cr20 | 2.0-3.3 | ≤1.2 | ≤1.5 | 18.0-23.0 | ≤3.0 |
High hardness with moderate toughness; excellent for impact-crusher blow bars and hammer tips
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| Cr26 | 2.0-3.3 | ≤1.2 | ≤1.5 | 23.0-30.0 | ≤2.0 |
Highest hardness for abrasive wear; best for fine crushing and grinding applications with low impact
