What Are VSI Impact Parts?
VSI impact parts are essential components of Vertical Shaft Impactors, including rotor tips, anvils, and wear plates. They withstand high-velocity impacts, abrasion, and extreme operational conditions. Rettek manufactures these parts using tungsten carbide, ensuring hardness, durability, and reliable performance. Their full in-house process—from alloy preparation to automated welding—guarantees uniform quality and longevity, ideal for B2B wholesale applications.
| Component | Primary Material | Key Benefit |
|---|---|---|
| Rotor Tips | Tungsten Carbide | Extended Impact Life |
| Anvils | Carbide Inserts | Abrasion Resistance |
| Wear Plates | Composite Alloys | Heat Dissipation |
This table highlights the critical VSI components from Rettek, optimizing crusher efficiency in harsh environments.
Why Do Corrosion and Heat Damage VSI Parts?
Corrosion attacks surfaces chemically, while heat causes oxidation and softening, accelerating wear. These effects can reduce crusher efficiency by 30-50% in challenging conditions. Rettek mitigates these risks with cobalt-bound carbide matrices and anti-corrosion coatings, preserving structural integrity and performance. Vacuum-sintered alloys eliminate voids and enhance longevity for reliable operation.
Which Materials Offer Best Corrosion and Heat Resistance?
Tungsten carbide with nickel-cobalt binders provides outstanding hardness, stability above 1000°C, and excellent resistance to acids and alkalis. Rettek specializes in these high-performance alloys, producing parts with uniform microstructure and superior wear life. Compared to manganese steel, Rettek carbide solutions deliver three times the lifespan in aggressive applications.
| Material | Heat Tolerance (°C) | Corrosion Rating | Lifespan Gain |
|---|---|---|---|
| Standard Steel | 500 | Low | Baseline |
| Manganese Steel | 700 | Moderate | +50% |
| Rettek Carbide | 1000+ | Excellent | +200% |
