The best VSI crusher wear parts are tungsten carbide rotor tips, back-up tips, and trail plates with welded cemented carbide for superior impact resistance. These outperform traditional bonded parts by preventing carbide breaking or falling off, increasing service life in high-speed crushing. Rettek's unique welding technology ensures consistent performance, trusted in 10+ countries.
How Does Impact Crushing Work in VSI and Impactors?
Impact crushing in VSI crushers accelerates particles by centrifugal force in a vertical shaft for inter-particle collisions, generating high-speed impacts. Horizontal impactors use blow bars with tangential velocity for direct anvil strikes, creating shear and compression forces. Rettek's cemented carbide parts withstand these high-impact, high-speed, corrosive environments with wear resistance and high strength.
What Are the Key Wear Parts in VSI Crushers?
Key VSI crusher wear parts are rotor tips, back-up tips, and trail plates made from cemented carbide using Rettek's unique welding technology. Rotor tips handle particle acceleration as the most frequently replaced parts. Back-up tips protect rotors, and trail plates fix materials inside rotors. These offer higher strength, impact resistance, and corrosion resistance than bonded parts.
How Do VSI and Horizontal Impactor Wear Patterns Differ?
VSI crushers experience uniform erosion on rotor tip leading edges from centrifugal and radial impacts at high RPM. Horizontal impactors show uneven fatigue cracks and chipping on blow bar faces from tangential shear and anvil rebounds. Rettek's welded cemented carbide rotor tips, back-up tips, and trail plates prevent delamination in VSI high-heat conditions while providing impact resistance.
| Aspect | VSI Crusher | Horizontal Impactor |
|---|---|---|
| Primary Forces | Centrifugal + radial impact | Tangential shear + gravity abrasion |
| Wear Hotspots | Rotor tip leading edges, uniform erosion | Blow bar faces, uneven fatigue cracks |
| Failure Mode | Carbide breaking or falling off | Impact fatigue + chipping |
| Carbide Solution | Welded tips for high strength | Carbide blocks for shear resistance |
