The VSI Sand Making Machine is the core equipment for artificial sand production in mining, construction, and infrastructure industries. It is specially designed for processing hard and abrasive materials like granite, basalt, and river pebbles, as well as recycling construction waste and concrete debris. Featuring a unique rock-on-rock crushing principle, it produces perfectly cubic-shaped sand particles with high production efficiency and low wear costs. As the key equipment in sand manufacturing plants, it offers fully automatic operation and adjustable gradation control, serving as essential equipment in modern aggregate production lines.
When selecting models, proper configuration should be optimized based on material hardness (VSI-7611 for granite, VSI-8518 for basalt) and production requirements (including closed-circuit design and dust control systems). Future developments will focus on intelligent control and energy-saving technologies to further enhance sand shaping quality and environmental performance.
Material characteristics: Compressive strength ≥150MPa, high abrasiveness, difficult shaping
Optimized configuration:
• Rotor recommendation: Four-port deep cavity design
• Wear-resistant parts: Tungsten carbide-tipped alloy
• Speed setting: 55-60m/s peripheral speed
Case: Vietnam granite sand plant using VSI-1140 achieves 120t/h output with <5% needle content
Material characteristics: Moderate abrasiveness, easier crushing, moisture sensitivity
Optimized configuration:
• Rotor recommendation: Three-port standard design
• Wear-resistant parts: High-chrome alloy
• Speed setting: 45-50m/s peripheral speed
Case: Malaysian limestone project with VSI-7611 produces 80t/h ideal sand for concrete mixing
Material Applications for VSI Sand Making Machine:
High-Hardness Rock Processing
▸ Granite ▸ Basalt ▸ River pebbles
Applications: Produces premium sand for high-strength concrete, architectural precast components, and major infrastructure projects like bridges and highways.
Medium-Hard Materials
▸ Limestone ▸ Dolomite ▸ Recycled concrete
Applications: Ideal for commercial ready-mix concrete plants, dry-mix mortar production, and urban construction waste recycling programs.
Specialized Uses
Processes industrial byproducts like blast furnace slag into quality construction sand, supporting sustainable building material production.
*The output will vary according to different materials, feed particle size and other factors
