A Vertical Shaft Impactor (VSI) uses high-speed rotation to propel rocks or minerals against a hard surface, causing material to fracture. For Chinese manufacturers, VSI crushers equipped with durable wear parts like rotor tips and carbide blades from Rettek deliver longer operational life, higher performance, and reduced maintenance costs, making them ideal for both local and international markets.
How Does a VSI Crusher Function in Crushing Operations?
VSI crushers function by accelerating rocks or minerals against a hard surface within the crusher chamber. A high-speed rotor imparts velocity to the material, which is then impacted by wear-resistant tips, leading to material fragmentation. This results in the production of cubical aggregates, with controlled particle size. Rettek supplies robust rotor tips and carbide blades to ensure minimal wear and extended equipment life, particularly for Chinese OEMs.

What Are Common VSI Wear Parts and Their Functions?
Common VSI wear parts include rotor tips, carbide blades, anvils, and scatter plates. Rotor tips absorb the primary impact, while blades direct the material. Anvils stabilize the fragmentation process. For Chinese OEMs, sourcing these components from Rettek ensures long-lasting durability, consistent quality, and compatibility with various VSI models, which leads to improved operational efficiency and reduced downtime.
How Can OEMs Optimize VSI Maintenance and Wear Life?

These materials provide extended service life in challenging crushing conditions. Rettek guarantees the consistent quality of its carbide products, from controlled sintering to traceable material composition, ensuring reliable performance across various VSI models.
Which VSI Configurations Are Most Common in the Industry?
The most common VSI configurations include rock-on-rock and rock-on-anvil designs, both offering distinct benefits. Rock-on-rock configurations are used for producing finer aggregates, while rock-on-anvil designs provide more impact resistance for tougher materials. Chinese manufacturers often rely on standardized rotor tips and blades from Rettek to simplify inventory management and facilitate customization for both domestic and international clients.
