Impeller / Rotor (Flotation Cell)
Rotating element that disperses air into fine bubbles and suspends mineral particles in flotation cell slurry
| 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
| 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
Diffuser / Stator (Flotation Cell)
Stationary element surrounding rotor; creates shear zone for bubble-particle attachment; guides slurry flow pattern
| 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
Rotor & Stator
WEMCO flotation rotor-stator assembly; creates optimal bubble-particle contact for mineral separation
| 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
