Description
Quick Overview: SUNWE VSI Crusher
The SUNWE Vertical Shaft Impactor (VSI) is an advanced rock crushing and sand making machine designed for high-capacity aggregate shaping. Operating with 4 flexible working modes and deep-chamber rotor technology, it delivers uniform, cubical aggregates that strictly comply with international ASTM and EN standards for high-strength concrete and asphalt manufacturing.
High-Performance Vertical Shaft Impact (VSI) Broyeur | Premium Sand Making Machine
The SUNWE Vertical Shaft Impact (VSI) Broyeur is an industry-leading solution engineered for high-capacity rock crushing, precise aggregate shaping, and premium manufactured sand (M-sand) production. Designed for maximum crushing efficiency, this vertical shaft impactor produces highly uniform, cubical aggregates perfectly suited for high-strength concrete, asphalt recycling, and industrial ceramics applications.
Compared to traditional jaw or cone crushers, the SUNWE VSI crusher delivers superior material particle shape, drastically reducing flakiness and elongated particles to meet the most stringent modern construction standards.
- International Compliance: The uniform cubical output ensures aggregate perfectly complies with global standards such as ASTM and EN standards for high-performance concrete mix design.
Typical Applications & Target Industries
- Suitable Raw Materials: Granite, basalt, quartzite, iron ore, and limestone.
- Target Industries: High-strength concrete production plants, M-sand (manufactured sand) processing plants, heavy infrastructure construction (roads, highways, and railways), and asphalt recycling facilities.
Technical Parameters of SUNWE Vertical Shaft Impact Crusher
| Model | Max.feed size(mm) | Max.feed size(mm) | Main shaft speed(r/min) | Power (KW) | ||
|---|---|---|---|---|---|---|
| Soft material | Hard material | Waterfall and central feed | Central feed | |||
| 8522 | 40 | 35 | 240-380 | 120-200 | 1550-1650 | 110*2 |
| 9526 | 45 | 40 | 280-350 | 150-180 | 1300-1500 | 132*2 |
| 9532 | 45 | 40 | 330-520 | 160-250 | 1350-1450 | 160*2 |
| 1145 | 50 | 45 | 400-500 | 220-330 | 1150-1250 | 220*2 |
| 1150 | 50 | 45 | 500-620 | 250-360 | 1100-1200 | 250*2 |
| 1263 | 60 | 50 | 545-583 | 454-486 | 900-1200 | 315*2 |
Note on Particle Size Distribution: The final output curve and the percentage of crushed products passing through the tight-side discharge opening depend heavily on the material’s Work Index ($W_i$), moisture content, and feed size distribution.
Key Features & Technological Advantages
1. Four Flexible Working Modes for Versatile Processing
To meet diverse aggregate processing requirements, the SUNWE VSI crusher seamlessly transitions between four distinct configurations:
- Full Center Feeding: Optimizes high-ratio reduction and intense material-on-material impact.
- Center Feeding with Waterfall Feeding: Maximizes hourly throughput and overall energy efficiency by introducing a secondary material stream.
- Rock-on-Rock (Stone-on-Stone): Utilizes an ore lining pocket allowing rocks to crush each other, drastically cutting down wear part consumption for highly abrasive hard rocks.
- Rock-on-Iron: Ejects material against heavy-duty anvil ring hammerheads to maximize the crushing ratio for less abrasive materials.
2. Deep-Chamber Rotor & Optimized Impeller Design
Equipped with a proprietary deep-cavity rotor, our VSI crusher significantly reduces internal material flow resistance. The optimized impeller design ensures higher material processing capacity, superior crushing ratios, and boosted hourly throughput.
3. Cost-Saving Modular Hammerhead Design
Maintenance downtime is costly. Our advanced modular hammerhead structure allows operators to replace only the worn segments of the vertical impactor hammer while leaving undamaged parts intact. This increases wear parts utilization rate and significantly lowers long-term operational costs.
4. Streamlined Internal Flow Path
By optimizing the internal flow path of the impeller, the material throwing angle is precisely controlled. This prevents premature wear on outer edges, prolongs the lifespan of wear-resistant components, and keeps maintenance overhead minimal.
VSI Crusher Working Principle
- Feed & Acceleration: Raw material enters the high-speed rotating impeller through the central feed hopper.
- High-Velocity Ejection: Centrifugal force accelerates the material, launching it through evenly distributed flow channels at velocities ranging from 60 à 80 m/s.
- Impact & Friction: Accelerated rocks collide violently with either the internal ore lining (Rock-on-Rock mode) or the impact anvil hammerheads (Rock-on-Iron mode).
- Discharge: After undergoing multiple rounds of impact, attrition, and shaping inside the chamber, finished cubical aggregates are discharged through the lower outlet.
VSI Crusher vs. HSI Crusher: Which One Do You Need?
When choosing between a Vertical Shaft Impactor (VSI) and a Horizontal Shaft Impactor (HSI), understanding the mechanism and specific output goals is critical:
| Feature / Specification | VSI Crusher (Vertical Shaft Impactor) | HSI Crusher (Horizontal Shaft Impactor) |
|---|---|---|
| Crushing Mechanism | Uses a vertical rotor and centrifugal force (Impact + Friction). | Uses a horizontal rotor with blow bars/hammers (Direct Mechanical Impact). |
| Primary Output | Fine aggregates, manufactured sand (M-sand), precision shaping. | Primary/Secondary crushing, recycling, coarser aggregates. |
| Particle Shape | Highly uniform, cubical shape (Ideal for high-strength concrete). | Less uniform; higher percentage of flaky/elongated particles. |
| Material Hardness | Excels at hard, highly abrasive rocks (Granite, Basalt, Quartzite). | Best suited for soft-to-medium hard materials (Limestone). |
| Wear Costs | Lower (when operating in Rock-on-Rock mode). | Higher when processing highly abrasive materials. |
Frequently Asked Questions (FAQ)
Q: What is the maximum feed size for the SUNWE VSI Crusher?
A: The maximum feed size ranges from 40 mm to 60 mm, depending on the specific machine model and material hardness.
Q: How does the Rock-on-Rock mode reduce operating costs?
A: It allows rocks to collide with each other rather than metal components, reducing inner liner wear by up to 50% when processing abrasive materials.
