VSI Vertical Shaft Impact Crusher for Particle Shape Optimization in Concrete Aggregates
June 2nd 2025
In the production of high-quality concrete, aggregate particle shape and gradation play a critical role in ensuring the performance of the final mix. VSI (Vertical Shaft Impact) crushers are widely used in sand and aggregate production lines for shaping and refining coarse and fine aggregates, especially to meet the demands of modern concrete specifications.
Why Particle Shape Matters in Concrete Aggregates
Concrete made with well-shaped aggregates displays:
Higher compressive strength
Improved workability
Reduced void content
Better cement paste bonding
Poorly shaped particles like flakes and elongated stones can compromise concrete’s performance. This is where VSI crushers become essential.

How VSI Crushers Work in Shaping Aggregates
A VSI crusher uses high-speed rotor centrifugal force to throw aggregates against a rock-lined crushing chamber, effectively breaking them into uniform, cubical particles.
Key features:
Rock-on-rock or rock-on-steel crushing options
Adjustable rotor speed and feed rate
Consistent product shape with low flakiness index
Ideal for producing manufactured sand (M-sand)
Applications in Concrete Aggregate Processing
VSI vertical shaft impact crushers are used to process:
Granite
Limestone
Basalt
River pebble
Gravel
And transform them into:
Well-shaped coarse aggregate (5–20 mm)
Fine manufactured sand (≤ 5 mm)
Graded mix for ready-mix concrete plants
Benefits of VSI Crusher in Concrete Aggregate Lines
✅ Superior Particle Shape: Produces cubical particles ideal for concrete and asphalt.
✅ High Production Capacity: Can reach up to 300 TPH in continuous operation.
✅ Low Operating Cost: Wear parts are optimized for longer life and easy replacement.
✅ Flexible Configuration: Easily integrated with mobile or stationary crushing setups.
Use Case Example: VSI Crusher in a 200 TPH Concrete Aggregate Plant
Input material: 30–40 mm gravel
Output products: 5–10 mm, 10–20 mm, and manufactured sand
Target application: High-strength concrete for infrastructure projects
