Shell Liner / Grinding Ball
Protects MShR (МШР) ball mill shell; grinding balls and liner plates for Russian-standard wet grinding mills
| 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 Panel
MSHR ball mill discharge grate; Cr26 high-chrome option for Russian grinding circuit applications
| 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
Trunnion Liner
MSHR mill trunnion liner; protects feed/discharge trunnion from pulp abrasion
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| Cr15 | 2.0-3.3 | ≤1.2 | ≤1.5 | 13.0-18.0 | ≤3.0 |
Balanced hardness-toughness ratio; versatile for medium-impact applications
| 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
