Impellers, Liners, Throatbush
Rotating impeller accelerates slurry; volute liner converts kinetic energy to pressure; both face severe abrasive/erosive wear from solids
| 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
| Grade | Base | Hardness | Tensile | Abrasion |
|---|---|---|---|---|
| Natural Rubber / Polyurethane | NR/SBR or PU | Shore A 50-75 | ≥ 20 MPa | DIN ≤ 150 mm³ |
Superior corrosion and cavitation resistance; reduces noise by 50-70%; ideal for slurry pump liners and flotation cell impellers in acidic/corrosive environments
KREBS pump wet-end liners; rubber or high-chrome iron options for different slurry conditions
| 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
