A Dry Sand Making System is a process that produces artificial sand (manufactured sand or M-Sand) without using water, making it environmentally friendly and cost-effective compared to traditional wet sand production methods. This system is widely used in construction, mining, and aggregate industries where high-quality sand with controlled particle size distribution is required.
Key Components of a Dry Sand Making System
1. Primary Crusher
– Jaw crusher or gyratory crusher breaks large rocks into smaller pieces.
2. Secondary Crusher (Optional)
– Cone crusher or impact crusher further reduces the size of the material.
3. Vibrating Feeder & Screen
– Ensures uniform feeding of raw material into the system.
– Screens remove oversized particles for re-crushing.
4. Dry Sand Maker (Vertical Shaft Impact Crusher – VSI)
– The core machine that shapes and refines sand particles through high-speed impact crushing.
– Produces well-graded, cubical-shaped sand ideal for concrete and asphalt.
5. Air Classifier (Optional for Fine-tuning)
– Separates fine and coarse particles to achieve desired gradation.
– Adjusts fineness modulus by removing excess fines.
6. Dust Collection System (Cyclone + Bag Filter or Pulse Jet Filter)
– Controls dust emissions, ensuring compliance with environmental regulations.
– Recovers fine particles that can be reused.
7. Conveying System
– Belt conveyors transport crushed material between stages.
8. Control System (Automation & Monitoring)
– PLC-based automation ensures efficient operation with minimal manual intervention.
Advantages of Dry Sand Making Systems
✔ No Water Usage – Ideal for arid regions or areas with water scarcity.
✔ Lower Operating Costs – Eliminates water treatment and sludge disposal expenses.
✔ Better Particle Shape & Gradation – Produces high-quality M-Sand comparable to natural river sand.
✔ Environmentally Friendly – Reduces water pollution and dust emissions with proper filtration.
✔ Higher Flexibility – Adjustable settings allow production of different sand grades for various applications.
Applications of Dry-Made Sand
– Ready-mix concrete
– Precast concrete products
– Asphalt mix for road construction
– Plastering and masonry work
