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) Penghancur kesan aci menegak (VSI Crusher)
- Prinsip: Uses high-speed rotor and anvils to crush rocks into cubical sand particles.
- Kelebihan:
- Produces well-graded, angular sand ideal for concrete.
- Low fines generation (adjustable gradation).
- Energy-efficient compared to other crushers.
- Aplikasi: Best for hard rocks (granit, basalt).

# (2) High-Efficiency Fine Crusher
- Suitable for softer materials (batu kapur, dolomit).
- 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. Peralatan Bantu
- 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).
- Skrin bergetar: Classifies sand into different sizes (0-5mm for concrete).

3. Key Considerations for Concrete Sand Production
- Bentuk zarah: Cubical grains enhance workability and strength.
- Penggredan: Must meet ASTM C33 or local standards (mis., 0–5mm wit

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

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

5. Alam sekitar & Faktor Kos
- Dust control systems (bag filters, water spray).
- Energy consumption vs. output optimization.
