Tooth Segment / Pick Assembly
Replaceable tooth segments for Gundlach Multi-Roll crushers (2000-5000 Series); precision sizing of coal, salt and friable materials
| 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
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| ZG30CrNiMo | 0.26-0.34 | 0.40-0.80 | 0.60-1.00 | 0.90-1.30 | 0.15-0.25 | 0.90-1.30 |
Ni substitution for Mn increases toughness by 67% vs ZG30CrMnMo (AKV 20-25J vs 10-15J); essential for heavy tooth picks (>25kg) with higher bending moment
| Grade | C | Si | Mn | Cr | Mo | Ni |
|---|---|---|---|---|---|---|
| Mn13Cr2 | 1.05-1.20 | ≤1.0 | 11.5-14.0 | 1.5-2.5 | — | — |
Excellent work-hardening capability; surface hardness increases under impact, ideal for moderate to high impact crushing conditions
Gear Ring / Drive Component
Gundlach multi-roll crusher gear rings; synchronized roll rotation for consistent product sizing
| Grade | C | Si | Mn | Cr | Mo |
|---|---|---|---|---|---|
| AISI 4140 | 0.38-0.43 | 0.15-0.35 | 0.75-1.0 | 0.8-1.1 | 0.15-0.25 |
Forged high-strength steel for shafts, bolts and high-stress components
Breaker Plate
Gundlach breaker plates for material sizing after initial roll crushing
| Grade | C | Si | Mn | Cr |
|---|---|---|---|---|
| Mn13Cr2 | 1.05-1.35 | ≤1.0 | 11.0-14.0 | 1.5-2.5 |
Standard work-hardening steel; cost-effective for moderate impact applications
| 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
