VIEW PRODUCTSBest Crusher Wear Parts Suppliers for Mining Companies: Technical Selection & Procurement Guide 2026
Jun 09,2026
1. Definition
Crusher wear parts are engineered consumables that directly contact and fracture ore inside crushing equipment. They include:
Jaw plates (fixed and moving) for jaw crushers
Mantle and concave for cone crushers and gyratory crushers
Blow bars and impact plates for impact crushers
Rotor tips and anvils for VSI crushers
These parts are manufactured primarily from manganese steel (Mn13, Mn18, Mn22) due to its unique work-hardening property.
2. Working Principle – Metallurgy Focus
Manganese steel is austenitic. Under impact from ore, the surface layer transforms into a hard martensitic structure (up to 550–600 HB), while the core remains tough and ductile.
Critical condition: Sufficient impact energy must be applied. If ore is too soft (e.g., certain limestone or coal), work-hardening does not activate, and wear accelerates.
3. Benefits of Properly Selected Crusher Wear Parts
| Benefit | Engineering Explanation |
|---|---|
| Longer wear life | Higher manganese grade and optimal heat treatment |
| Lower cost per ton | Extended life + lower part price |
| Less downtime | Fewer liner changes per year |
| Stable product size | Consistent crushing chamber profile |
| Lower energy draw | Optimised liner geometry reduces friction |
4. Applications by Industry and Ore
Industry Application Matrix
| Industry | Typical Crusher Type | Recommended Wear Part | Manganese Grade |
|---|---|---|---|
| Iron ore | Cone / Gyratory | Mantle + concave | Mn22 |
| Copper ore | Cone / Gyratory | Mantle + concave | Mn18–22 |
| Gold ore | Jaw + Cone | Jaw plate, mantle | Mn18 |
| Lithium ore | Jaw crusher | Jaw plate | Mn13–18 |
| Silica sand | VSI | Rotor tips | Mn22 / chrome |
| Coal | Impact / Hammer | Blow bar | Mn13 |
| Aggregates | Jaw / Cone / Impact | All types | Mn18 |
5. Comparison: Aftermarket vs OEM – Detailed
| Parameter | OEM (Metso, Sandvik) | Quality Aftermarket (HUATAO) |
|---|---|---|
| Wear life | 100% baseline | 90–98% (field-proven) |
| Price (per set) | 100% | 50–70% |
| Cost per ton | baseline | 20–35% lower |
| Lead time (weeks) | 8–16 | 3–6 |
| Customisation | None or very limited | Full (any drawing) |
| Engineering support | Limited after sale | Full technical support |
| Material certificate | Yes | Yes (chemical + mechanical) |
| Foundry ownership | Usually outsourced | Own foundry (HUATAO) |
Conclusion for procurement: For copper, gold, iron ore, lithium and aggregates, quality aftermarket wear parts provide superior total value.
6. Selection Guide for Mining Engineers
Step-by-step:
Document your crusher: Make, model, serial number
Collect OEM part number (if available)
Obtain drawing (PDF/DXF/DWG) or provide sample
Characterise ore: Abrasivity index (Ai), work index (Wi), top size (F80)
Select manganese grade:
Mn13: low impact, soft rock, coal
Mn18: standard for most metallic ores
Mn22: high impact, high abrasion (iron, silica, copper porphyry)
Request quotation with lead time
Verify supplier foundry certification (ISO 9001, material testing lab)
7. Failure Analysis – Detailed Table
| Failure Mode | Visual Sign | Root Cause | Corrective Action |
|---|---|---|---|
| Premature cracking | Cracks through thick section | Low Mn grade / poor heat treatment / hydrogen embrittlement | Switch to certified Mn18/Mn22 foundry, request hardness report (350–400 HB as-cast) |
| Uneven wear (high-low) | One side worn more | Incorrect CSS, feed segregation, or crusher speed | Adjust CSS weekly, install feed distributor, check eccentric speed |
| Plastic deformation (bulging) | Liner surface bulging outward | Oversize feed exceeding design | Install grizzly or reduce top size |
| Low work hardening | Soft, smeared surface | Ore too soft or insufficient impact | Increase crusher speed or change to Mn13 (better low-impact performance) |
| Broken lug / mounting | Liner loose in crusher | Improper wedge tightening or worn seating area | Torque to specification, inspect crusher frame seating |
8. Maintenance Guide for Crusher Liners
Daily
Listen for knocking sounds (loose liner)
Monitor power draw and current peaks
Weekly
Measure closed side setting (CSS) at three points
Record product P80 (size analysis)
Per liner change
Record total tonnes and operating hours
Photograph worn liner profile
Weigh new liner (baseline)
Compare actual vs expected life
Storage best practice
Store manganese liners indoors or under cover
Prevent rust pitting (affects work hardening)
Keep matching sets together
9. Procurement Guide for Mining Companies
Required information for supplier:
Crusher make/model (e.g. Sandvik CH660, Metso HP400, Terex JW42)
OEM part number (if available)
Technical drawing (PDF, DXF, DWG, or STEP)
Ore type, feed F80, and abrasivity index
Desired manganese grade (Mn13/18/22)
Target wear life (hours or tonnes)
MOQ requirement (usually 1 set)
Lead time requirement
Shipping port and preferred packing (steel pallet + fumigated wood)
Supplier evaluation checklist:
Own foundry?
In-house heat treatment?
Material test certificates provided?
Can produce from customer drawing?
Lead time ≤30 days for custom parts?
References from similar ore applications?
