VSI impact parts with tungsten carbide inserts provide exceptional wear life and high-impact durability, often lasting 2-3 times longer than standard high-chrome steel. Rettek, a leading China manufacturer, produces rotor tips, anvils, and wear plates via vacuum sintering for dense, high-performance components. These wholesale OEM solutions minimize downtime, reduce operational costs, and improve crusher efficiency in mining and aggregates.
What Are VSI Impact Parts?
VSI impact parts are essential wear components in Vertical Shaft Impact crushers, including rotor tips, anvils, cavity plates, and side liners. They endure high-speed particle collisions and material acceleration. Rettek designs these parts for both rock-on-rock and rock-on-anvil configurations, ensuring optimal particle shape, throughput, and reduced wear frequency. Full-chain production, from alloy preparation to automated welding, guarantees consistent quality for abrasive materials like basalt and granite. Custom grades support feed-specific requirements for improved ROI in sand-making lines.
| VSI Part Type | Function | Typical Lifespan |
|---|---|---|
| Rotor Tips | Accelerate material | 400-800 hours |
| Anvils | Impact surface | 500-1000 hours |
| Cavity Plates | Protect rotor flow | 300-600 hours |
VSI impact parts are the key components in Vertical Shaft Impact crushers that take the force of high-speed rock collisions. This includes rotor tips, anvils, cavity plates, and side liners. Rotor tips speed up the material, while anvils act as impact surfaces to break it. Cavity plates and liners protect the internal parts of the crusher from wear. These parts are essential for producing properly shaped sand and maintaining steady output.
Rettek designs VSI parts for both rock-on-rock and rock-on-anvil setups, using a complete in-house production process from alloy preparation to automated welding. This ensures consistent quality and long-lasting performance, even with hard rocks like basalt and granite. They also offer custom material grades to match specific feeds, helping operators get the best performance and return on investment.
Why Choose Tungsten Carbide for High-Impact Resistance?
Tungsten carbide delivers superior hardness (HRA 89-92) and toughness, resisting abrasion 2-3 times better than high-chrome alloys. Rettek uses vacuum-sintered carbide to maintain dense microstructure and shape under repeated high-velocity impacts. Micro-grain grades like YG8 or YL10.2 balance impact resistance and wear, reducing operational costs by 30-40%. Advanced brazing prevents tip loss, while maintaining crusher efficiency and lowering energy consumption, providing durable solutions for harsh quarrying and recycling environments.
Tungsten carbide is used for parts that face high impacts because it is extremely hard and tough. It can resist abrasion two to three times better than standard high-chrome alloys, which means the parts last longer even under constant collisions in crushers. Micro-grain carbide grades, such as YG8 or YL10.2, provide a good balance between impact resistance and wear, helping machines operate efficiently without frequent replacements.
Rettek uses vacuum-sintered carbide to ensure the material stays dense and keeps its shape under repeated high-speed impacts. Advanced brazing techniques secure tips to prevent loss during operation. Using tungsten carbide parts not only improves crusher efficiency but also lowers energy use and reduces operating costs by 30–40%, making them ideal for tough quarrying and recycling environments.
How Do VSI Impact Parts Enhance Abrasion Resistance?
VSI impact parts improve abrasion resistance through carbide overlays on high-strength steel bases, protecting high-wear areas from silica-rich feeds. Rettek designs feature angled tips for even wear distribution. Advanced pressing and sintering achieve uniform density (14.5-14.9 g/cm³), withstanding gravel and ore abrasion. Customized OEM solutions match machine models for seamless fit. These parts reduce fines, improve cubicity, and maintain high-throughput performance in demanding operations.

Their innovation in high-impact designs is trusted by B2B partners worldwide.
Which VSI Parts Handle Extreme High-Impact Best?
Rotor tips and anvils perform best in high-impact zones, absorbing shock with tungsten carbide inserts. Backup tips provide protection during overloads. Rettek’s reinforced designs endure over 1000 hours in challenging aggregate conditions. Grades with higher cobalt content enhance toughness and outperform standard parts in mining crushers.
| Material Grade | Impact Rating | Abrasion Rating | Rettek Application |
|---|---|---|---|
| YG6X | High | Excellent | Rotor Tips |
| YL10.2 | Very High | High | Anvils |
| YG8 | Medium-High | Superior | Wear Plates |
