Roll segments, Crushing segments
Crushing Roll Shell / Segment
Eccentric roll surface in ERC 18-14 to ERC 25-30; combines gyratory compression with roll crushing for primary reduction
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| ZG30CrMnMo | 0.26-0.34 | 0.40-0.80 | 0.90-1.30 | 0.90-1.30 | 0.15-0.25 | — |
Excellent balance of hardness and toughness; optimized for sizer tooth picks under combined impact + shear loading
Jaw Plate (Fixed Crushing Surface)
Stationary counter-crushing surface; works with rotating roll shell to create wedge-shaped crushing zone
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Mn18Cr2 | 1.05-1.35 | ≤1.0 | 16.0-19.0 | 1.5-2.5 | — | — |
Higher Mn content provides superior work-hardening depth; 20-30% longer service life than Mn13 in high-compression applications
Impact Bar / Crusher Segment
ERC eccentric roll crusher impact segments; replaceable crushing surface on roll
| Grade | C | Si | Mn | Cr |
|---|---|---|---|---|
| Mn18Cr2 | 1.05-1.35 | ≤1.0 | 16.0-19.0 | 1.5-2.5 |
Superior work-hardening depth; 20-30% longer life than Mn13 in high-compression applications
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| ZG30CrMnMo | 0.25-0.35 | 0.3-0.6 | 0.8-1.2 | 0.8-1.2 | 0.15-0.30 |
High strength and wear resistance for sizer tooth applications; verified composition with full QC documentation
