SOLUTION COMPARISON
Comparison of Materials and Process Solutions for Excavation Wear Parts
Select appropriate wear-resistant materials and processes based on different working conditions to balance service life and cost.
| Solution | Applicable Scenario | Process/Material | Cost | Core Performance | Best Scenario |
|---|---|---|---|---|---|
| Teeth (NM500 Wear-Resistant Steel) | Rock hardness f≤12, moderate impact load | Forging + quenching + tempering heat treatment | Medium Welding of wear-resistant steel requires preheating and post-heating, increasing process control costs. | Hardness HRC50-55, excellent wear resistance | Suitable for excavator and loader bucket teeth |
| Picks (YG8 Cemented Carbide) TOP PICK | Coal rock cutting, medium to low hardness rock | Brazed cemented carbide tip | High Cemented carbide raw materials rely on imports, with high price volatility. | High impact resistance, efficient cutting | Suitable for cutting by shearers and roadheaders |
| Crusher Hammers/Liners (High-Chromium Cast Iron Cr26) | Low impact, high abrasion crushing conditions | Composite casting + modification treatment | High Induction quenching is efficient and suitable for mass production. | Hardness HRC60-65, excellent wear resistance, suitable for low impact high abrasion conditions | Suitable for low-impact, high-abrasion areas such as fixed jaw plates of jaw crushers and screen plates of hammer crushers |
Selection should comprehensively consider factors such as rock hardness, impact frequency, and replacement cost.
SELECTION DECISION
How to Choose the Right Wear Parts Solution?
Select the optimal solution based on working condition characteristics.
01
Selection by Rock Hardness
Match material hardness with rock hardness
- f≤8 choose NM400, f=8-12 choose NM500, f>12 choose high-chromium cast iron
- Avoid over-configuration or premature failure
Selection by Rock HardnessSolutions →
02
Selection by Impact Frequency
Balance toughness and hardness
- High-frequency impact choose high-manganese steel, low-frequency choose high-chromium cast iron
- Extend service life and reduce replacement frequency
Selection by Impact FrequencySolutions →
03
Selection by Replacement Cost
Optimize total lifecycle cost
- Choose economical type for easily replaceable parts, long-lasting type for hard-to-replace parts
- Reduce downtime losses and improve production efficiency

ENGINEERING CASES
Typical Application Cases
The following are actual application data of excavation wear parts in different mines.
| Configuration Item | Typical Specification/Requirement | Design Basis/Source |
|---|---|---|
| Open-Pit Iron Mine | Tooth service life increased by 40%, replacement cycle extended from 15 days to 21 days | Data from a large iron mine in 2024 |
| Fully Mechanized Coal Mining | Pick consumption reduced by 35%, single-shift cutting efficiency increased by 20% | Report from a coal mine in Shanxi in 2024 |
| Sand and Gravel Aggregate | Crusher hammer life reached 800 hours, liner replacement cycle extended to 3 months | Case from a sand and gravel plant in East China |
Actual service life is affected by factors such as ore properties, operating practices, and maintenance levels.
The above data are for reference only; actual results depend on specific working conditions.
