Best Crusher Wear Parts Suppliers for Mining Companies: Engineering Guide & Procurement Checklist
-
admin - 28 Jul, 2026
1. Definition
Crusher wear parts are consumable components installed inside crushing equipment. They directly contact and break the ore. Examples include jaw plates, mantles, concaves, blow bars and impact plates.
These parts are designed to be replaced periodically. Their wear life determines maintenance frequency and overall crushing cost.
2. Working Principle
Manganese steel work-hardens under impact. As the crusher operates, the surface hardness increases from ~220 HB to over 550 HB. This creates a hard, wear-resistant surface while the core remains tough.
If the ore is too soft or feed size too small, work-hardening does not occur properly, leading to premature wear.
3. Benefits of Optimised Crusher Wear Parts
- Reduced downtime per 10,000 tons crushed
- Lower power draw (less friction)
- More consistent product P80
- Reduced risk of liner breakage
- Lower total cost per ton
4. Applications
By Crusher Type:
- Jaw crushers: jaw plates (fixed + moving)
- Cone crushers: mantle + concave
- Impact crushers: blow bar, impact plate
- VSI crushers: anvils, rotor tips
By Ore Type:
| Ore | Recommended Mn Grade | Expected Life Advantage |
|---|---|---|
| Iron ore | Mn22 | +30% vs Mn18 |
| Copper ore | Mn18 | baseline |
| Gold ore | Mn18 | baseline |
| Lithium ore | Mn13–18 | +20% with correct CSS |
| Silica sand | Mn18–22 | high abrasion, +40% |
| Coal | Mn13 | impact instead of abrasion |
5. Comparison: Quality Aftermarket vs OEM
| Parameter | OEM (Metso/Sandvik) | Quality Aftermarket (HUATAO) |
|---|---|---|
| Wear life | 100% reference | 90–98% |
| Price | 100% | 50–70% |
| Lead time | 8–16 weeks | 3–6 weeks |
| Custom geometry | No | Yes (any drawing) |
| Technical support | Limited after sale | Full engineering support |
| Material traceability | Yes | Yes (certificate provided) |
Verdict: For most mining operations (copper, gold, aggregates, coal, lithium), quality aftermarket wear parts offer superior value.
6. Selection Guide
Step 1: Identify your crusher model (e.g. Sandvik CH440, Metso HP300)
Step 2: Determine ore type and abrasivity index (Ai)
Step 3: Choose manganese grade:
- Mn13: low impact, softer ores
- Mn18: general purpose, good for gold and copper
- Mn22: high impact, high abrasion (iron ore, silica)
Step 4: Request quotation with drawing or OEM number
Step 5: Verify foundry certifications (ISO 9001, material testing)
7. Failure Analysis
| Problem | Possible Cause | Solution |
|---|---|---|
| Cracking after short time | Poor heat treatment / low Mn grade | Use certified Mn18/Mn22 foundry |
| Uneven liner wear | Incorrect CSS or feed segregation | Adjust CSS and use proper feed distributor |
| Plastic deformation (bulging) | Overload from oversize feed | Install grizzly or reduce feed top size |
| Low work hardening | Ore too soft or low impact | Increase crusher speed or change part design |
8. Maintenance Guide
- Daily: Listen for unusual knocking (loose liner)
- Weekly: Measure closed side setting (CSS) in 3 positions
- Per liner change: Record hours, tonnage, and final liner profile
- Storage: Keep manganese liners dry (prevent rust pitting)
9. Procurement Guide
Information to provide to your supplier:
- Crusher make, model, serial number
- OEM part number (if available)
- Drawing (PDF/DXF/DWG)
- Ore type and feed size (F80)
- Expected daily crushing tonnage
- Desired wear life (hours or tons)
- Manganese grade preference
Supplier Evaluation Checklist:
- Own foundry?
- Mn13/18/22 capability?
- Heat treatment furnaces and records?
- Can produce from customer drawing?
- Lead time ≤30 days?
- Past mining references?
10. Case Study – Iron Ore Mine, Brazil
Customer type: Open-pit iron ore mine, 15,000 t/day
Crusher: Sandvik CH660 cone crusher
Original wear parts: OEM concaves, 1,800 hours life
Problem: High cost per ton, long OEM lead time (14 weeks)
Solution: HUATAO Mn22 concaves, modified profile to match ore abrasivity
Result:
- Wear life: 2,300 hours (+28%)
- Price: 45% lower than OEM
- Cost per ton reduced 31%
- Lead time: 4 weeks
11. FAQ
Q1: What is the best manganese grade for copper ore?
A: Mn18 is standard. For very abrasive copper ores, Mn22 provides 20–30% longer life.
Q2: Can aftermarket parts fit exactly like OEM?
A: Yes, when produced from an original drawing or 3D scan.
Q3: How long do crusher wear parts last?
A: 2–12 weeks depending on ore, tonnage and crusher settings.
Q4: Does HUATAO provide parts for Metso and Sandvik?
A: Yes, for all major brands.
Q5: What is the MOQ?
A: Typically 1 set for wear parts.
Q6: Do you provide material certificates?
A: Yes, chemical composition and mechanical properties.
Q7: How to reduce wear part cost per ton?
A: Increase manganese grade, optimise CSS, use quality aftermarket supplier.
Q8: What is the lead time for custom parts?
A: 3–6 weeks including casting, heat treatment and machining.
12. Conclusion
