A sand making machine (also called a vertical shaft impact crusher – VSI) is used to produce artificial sand (M-sand) from rocks, stones, or construction waste. It’s essential in construction where natural river sand is limited or restricted.
Common Types of Sand Making Machines
- Vertical Shaft Impact (VSI) Crusher: The most popular modern choice for high-quality, cubical sand. It uses a “stone-on-stone” or “stone-on-iron” principle to shape and crush rocks.
- Hammer Sand Maker: Uses high-speed rotating hammers to strike materials. It is highly efficient for medium-hard or soft materials like limestone but may produce less uniform grain shapes.
- Roller Crusher: Crushes material by squeezing it between two rotating rollers. It is cost-effective and energy-efficient for softer, friable rocks.
- Compound Crusher: A vertical machine with no grate at the bottom, making it ideal for materials with high moisture content (up to 15%).
- Mobile Sand Maker: Integrated systems mounted on tracks or tires that can be moved directly to construction sites, saving on material transportation costs.
Applications
- Concrete production (RMC plants), Plaster sand manufacturing, Road base and asphalt Dam and infrastructure projects & Recycling construction waste.
