A VSI (Vertical Shaft Impact) crusher consists of critical wear parts like rotor tips, distributor plates, wear plates, and feed tubes. It is designed to crush materials through high-speed impact, producing fine, cubical products with high efficiency. Leading Chinese manufacturers like Rettek supply durable carbide wear parts, ensuring long tool life and stable crusher performance.
What Are the Main Parts of a VSI Crusher and Their Functions?
The main parts of a VSI crusher include rotor tips, distributor plates, upper and lower wear plates, backup tips, tip/cavity wear plates, trail plates, feed tubes, and feed eye rings. Rotor tips impact materials at high speed, breaking them down. Distributor plates evenly spread feed material. Wear plates protect structural components from abrasion. The feed tube channels material into the rotor. Each part is critical for crusher stability and efficiency.
How Are VSI Crusher Parts Manufactured in China Factories?
China’s VSI crusher parts manufacturers use advanced alloy batching, pressing, vacuum sintering, and automated welding to produce high-quality components. Factories like Rettek control the entire production chain from raw material preparation to finished carbide wear parts. This vertical integration ensures consistent quality and cost-effective wholesale production for OEM clients globally.
Why Are Wear-Resistant Carbide Parts Important for VSI Crushers?
Wear-resistant carbide parts dramatically extend the lifespan of crusher components exposed to high abrasion. These parts reduce downtime and operating costs for heavy-duty industrial crushers. Rettek’s carbide rotor tips and wear plates maintain sharpness and strength in harsh conditions, increasing crusher efficiency and service intervals for manufacturers and suppliers.
Which Materials Are Commonly Used for VSI Crusher Wear Parts?
Highly wear-resistant materials such as tungsten carbide alloys and chromium iron are typically used for VSI crusher parts. Tungsten carbide gives excellent hardness and wear resistance, ideal for rotor tips and blades. Chromium iron provides toughness and abrasion resistance for wear plates and distributor plates. Rettek combines proprietary alloys to optimize durability and performance.
| VSI Part | Material Used | Primary Benefit |
|---|---|---|
| Rotor Tips | Tungsten carbide | Long-lasting sharp impact edges |
| Distributor Plate | Chromium iron | High abrasion resistance |
| Wear Plates | Chromium iron alloys | Structural protection |
| Backup Tips | Tungsten carbide | Protects rotor during wear |
