Concrete-use sand making equipment is essential for producing high-quality artificial sand (manufactured sand or M-sand) as a substitute for natural sand in construction. Here are the key types of equipment and considerations:

1. Types of Sand Making Equipment
# (1) Vertical Shaft Impact Crusher (VSI Crusher)
- Principle: Uses high-speed rotor and anvils to crush rocks into cubical sand particles.
- Advantages:
- Produces well-graded, angular sand ideal for concrete.
- Low fines generation (adjustable gradation).
- Energy-efficient compared to other crushers.
- Applications: Best for hard rocks (granite, basalt).

# (2) High-Efficiency Fine Crusher
- Suitable for softer materials (limestone, dolomite).
- Produces uniform particle size with lower energy consumption.

# (3) Hammer Crusher
- Cost-effective but generates more flaky particles (less ideal for high-strength concrete).

# (4) Roll Crusher
- Used for secondary crushing to refine sand gradation.

2. Auxiliary Equipment
- Vibrating Feeder: Ensures steady material supply.
- Jaw/Cone Crusher: Primary crushing before sand making.
- Sand Washer: Removes excess dust and impurities (important for concrete quality).
- Vibrating Screen: Classifies sand into different sizes (0-5mm for concrete).

3. Key Considerations for Concrete Sand Production
- Particle Shape: Cubical grains enhance workability and strength.
- Gradation: Must meet ASTM C33 or local standards (e.g., 0–5mm wit

15% fines).
- Moisture Control: Wet processing reduces dust but requires drying for ready-mix concrete.

4. Popular Manufacturers
- , , (High-end VSI crushers)
- Liming Heavy Industry, SBM (Cost-effective solutions)

5. Environmental & Cost Factors
- Dust control systems (bag filters, water spray).
- Energy consumption vs. output optimization.
