Modern round-shaped sand making machines (also called vertical shaft impact crushers) are pivotal in producing high-quality manufactured sand for construction and infrastructure projects. These machines crush raw materials like granite, basalt, or river pebbles into cubical, well-graded sand particles.
The typical round sand production line includes:
1. Feeder: Uniformly supplies raw materials (e.g., 0–50mm crushed stone).
2. Sand Maker: Key model: VSI-1140 with 400–500t/h capacity, motor power 250–315kW.
3. Vibrating Screen: 3-layer screen with 4–20mm adjustable mesh size.
4. Sand Washer: Removes impurities (clay, dust) with 50–120t/h processing ability.
| Model | Capacity (t/h) | Max Feed Size (mm) | Motor Power (kW) |
|---|---|---|---|
| VSI-7611 | 60–180 | 35 | 180 |
| VSI-1145 | 200–500 | 50 | 400 |
Q1: How to reduce needle-like particles in output sand?
A: Adjust the rotor speed (optimal range: 1,800–2,200 rpm) and ensure feed size ≤50mm.
Q2: What’s the lifespan of wear parts?
A: Tungsten carbide tips last ~120 hours for granite; manganese steel anvils last ~300 hours.
Project: A highway construction in Malaysia (2023)
Solution: Deployed a VSI-1140 sand maker with a 300t/h capacity line, achieving ≤3% fines content and perfect gradation for asphalt mix. Post-sale data showed 18% lower operating costs vs. traditional jaw crusher setups.
