VSI impact parts are critical wear components used in vertical shaft impact (VSI) crushers to break down hard materials efficiently. Designed for longevity and performance, these wear parts help industries reduce downtime and operational costs through improved durability and precision engineering.
What Are VSI Impact Parts and Why Are They Important?
VSI impact parts are specialized wear-resistant components for VSI crushers, including tips, anvils, rotors, and wear plates. Their primary function is to absorb and resist the high-impact forces during crushing, ensuring extended machine life and consistent crushing performance. These parts are essential for industries processing hard materials like minerals, aggregates, and recycling.
How Are VSI Impact Parts Manufactured in China?
China's VSI impact parts manufacturing involves advanced carbide materials, precision molding, and vacuum sintering technologies. Leading manufacturers such as Rettek control the entire production chain—starting from raw alloy batching to pressing and welding—to guarantee consistent quality and optimized costs. This integrated process ensures durability and resistance against extreme wear conditions.
Which Materials Are Used for VSI Impact Parts?
Carbide alloys, particularly tungsten carbide mixed with cobalt, are the most common materials used for VSI impact parts due to their superior hardness and wear resistance. Rettek utilizes high-grade raw materials and innovative alloy blends to enhance toughness and extend the service life of their crusher tips, rotor parts, and inserts.
| Material Type | Hardness (HV) | Wear Resistance | Typical Application |
|---|---|---|---|
| Tungsten Carbide Coating | 1600-2200 | Very High | Crusher tips and impact plates |
| High-Speed Steel | 800-950 | Medium | Less abrasive materials |
| Cast Iron | 250-350 | Low | Basic wear parts |
