Dry fine sand making equipment is designed to produce high-quality artificial sand with precise particle size distribution, low moisture content, and minimal dust. This equipment is commonly used in construction, construção de estradas, e produção de concreto. Below are the key types of dry fine sand-making machines and their features:

1. Triturador de impacto de eixo vertical (Triturador VSI)
- Princípio: Uses high-speed rotor impact to crush rocks into fine sand.
- Vantagens:
- Produz bem moldado, cubical sand particles.
- Low moisture content (dry process).
- Adjustable fineness (0-5milímetros).
- Aplicativos: Concrete sand, areia asfáltica, areia manufaturada (Areia M).

2. Triturador fino de alta eficiência
- Princípio: Multi-stage crushing with impact and grinding.
- Vantagens:
- High crushing efficiency for fine particles (0-3milímetros).
- Low energy consumption.
- Aplicativos: Ultra-fine sand for high-strength concrete.

3. Sistema de fabricação de areia seca (Combined with Air Classifier)
- Componentes:
- Triturador primário (mandíbula/cone).
- VSI crusher for shaping.
- Air classifier for dust removal and gradation control.
- Vantagens:
- No water required (eco-friendly).
- Adjustable fineness and low silt content (<3%).
- Aplicativos: Premium dry-processed M-sand.

4. Roller Crusher (for Soft Materials)
- Princípio: Compression crushing between rollers.
- Vantagens:
- Low dust generation.
- Energy-efficient for limestone, gesso, etc..
- Aplicativos: Fine sand production from soft rocks.

5. Airflow Sieving & Dust Collection System
- Ensures ultra-dry (<1% umidade) and dust-free output.
- Works with VSI or fine crushers.

Key Considerations When Choosing Equipment:
- Raw Material Hardness (Granito, basalto, calcário?).
- Tamanho de saída desejado (0-3mm or 0-5mm?).
- Produ

on Capacity (50t/h vs. 200t/h?).
- Dust Control Needs (Dry systems require bag filters or cyclones).
