Roller tires, Studs, Cheek plates
Rolling surface that applies extreme pressure (up to 350 bar) to material bed; studded with WC pegs to create autogenous wear layer
| Grade | WC | Co | Other |
|---|---|---|---|
| WC-Co Cemented Carbide | 84-89% | 11-16% | ≤1% |
Extreme hardness for HPGR roller studs and VSI rotor tips; 5-10x longer life than Cr26 in pure abrasion; requires careful installation to avoid thermal shock
| Grade | C | Cr | Nb | W | Fe |
|---|---|---|---|---|---|
| Hardfacing Overlay (Cr-C) | 3.0-5.5 | 20.0-35.0 | 4.0-8.0 | 0-10.0 | Balance |
Weld overlay on cast steel base; can be re-welded 3-5 times for extended service life; cost-effective for VRM rollers and HPGR cheek plates
Prevents material extrusion at roller edges; hardfacing surface resists extreme abrasive wear
| 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
Polycom HPGR tungsten carbide studs forming autogenous wear layer on roll surface
| 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
