VSI Sand Making Machine

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.

Products Display

High-Hardness Materials (granite, basalt, river pebbles)

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
Medium-Hard Materials (limestone, dolomite, recycled concrete)

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 Application

Material Applications for VSI Sand Making Machine:
