What Makes VSI Carbide Inserts Essential for Crusher Rotors?
VSI carbide inserts, like Rettek rotor tips, protect rotors in high-abrasion environments of VSI crushers. Made from cemented carbide with unique welding, they prevent carbide breaking or falling off, increasing service life versus standard steel while saving maintenance costs in sand making, mining, and agricultural crushing.
How Is Tungsten Carbide for VSI Inserts Manufactured?
Rettek manufactures cemented carbide VSI inserts through full in-house control from alloy raw material preparation, batching, pressing, and vacuum sintering to tool design, production, and automated welding. This ensures consistent quality and stable performance for rotor tips, back-up tips, and trail plates.
| Stage | Rettek Process | Benefit |
|---|---|---|
| Mixing/Batching | Alloy raw material preparation and batching | Consistent material quality for uniform carbide |
| Pressing/Sintering | Pressing and vacuum sintering | Dense, defect-free structure for high strength |
| Welding/Finishing | Automated welding and tool production | Secure attachment, precise fit for VSI rotors |
Why Does Rettek's Vacuum Sintering Produce Superior VSI Inserts?
Rettek's proprietary vacuum sintering with full in-house chain produces superior cemented carbide VSI inserts like rotor tips. It ensures wear resistance, impact resistance, and corrosion resistance, solving carbide detachment issues for longer life in harsh VSI conditions compared to traditional methods.
How Do Custom Brazing and Welding Enhance Insert Performance?
Rettek's unique welding technology welds cemented carbide tips to rotor bodies, providing higher strength than bonded types. Automated welding processes ensure secure attachment, reducing vibration and detachment in high-speed VSI crushers, while boosting service life and cutting downtime costs.
Which VSI Carbide Insert Grades Match Your Crushing Needs?
Rettek customizes cemented carbide grades for VSI inserts based on stone material, equipment model, and crushing time. Options balance wear resistance, impact resistance, and corrosion resistance for sand making, mining wood chips, or agricultural crushing, with multiple grades available.
| Grade Type | Key Properties | Best For |
|---|---|---|
| High Wear Resistance | Superior wear and corrosion resistance | Sand making, aggregates |
| Impact Resistant | High strength and impact resistance | Mining, recycling |
| Corrosion Focused | High corrosion and wear resistance | Abrasive, wet conditions |
