Carbide rotor tips for vertical shaft impact (VSI) crushers are high-wear-resistant components made primarily from tungsten carbide. These tips are attached to the rotor to improve crushing efficiency and extend the service life of the rotor by resisting severe impact and abrasion. Leading manufacturers like Rettek specialize in producing durable carbide rotor tips with OEM customization and wholesale services.
What Are Carbide Rotor Tips for VSI Crushers?
Carbide rotor tips are replaceable parts mounted on the rotor of VSI crushers. They directly contact the feed material, accelerating it to high velocity for crushing by impact. Tungsten carbide tips offer excellent hardness and wear resistance, essential for minimizing downtime and maintenance costs in high-intensity crushing operations.
How Does Tungsten Carbide Improve VSI Crusher Rotor Tip Performance?
Tungsten carbide provides exceptional wear and impact resistance due to its extreme hardness and toughness. This metal alloy withstands abrasive materials and high-speed impact forces, significantly increasing rotor tip durability compared to traditional steel tips, reducing frequency of replacements and operational costs.
Which Types of Carbide Grades Are Used for Rotor Tips?
Different grades of tungsten carbide are tailored for specific crushing applications:
-
Hard Tungsten: High impact resistance, suitable for larger feed sizes.
-
Extra Hard Tungsten: Higher abrasion resistance for finer materials.
-
XX Hard Tungsten: Maximum abrasion resistance with lower impact tolerance.
Rettek customizes carbide grades based on client product and operating conditions.
