How is the Sand Output Performance of a Sand Making Machine?

A sand making machine is a specialized piece of equipment designed to produce manufactured sand (also known as artificial sand). With increasing restrictions on river sand mining, artificial sand has become a viable and sustainable alternative, offering quality comparable to natural sand—and in some cases, even superior.

These machines offer adjustable inlet and outlet settings, allowing for the production of sand in various particle sizes. For production lines requiring strict grain size control, screening systems and sand washing machines can be integrated to remove impurities and enhance the final product's quality.

Advantages of Manufactured Sand vs. Natural Sand

1. Strength: While slightly less strong than natural river sand, manufactured sand meets the GB/T14168-4293 standard and is fully suitable for regular concrete applications. Proper control of cement-to-sand ratio, crushing index, and stone powder content ensures reliable performance.

2. Particle Shape & Bonding: Manufactured sand particles are more irregular and curved, improving the bond with cement and enhancing compressive strength, resulting in longer-lasting concrete structures.

3. Compatibility with Concrete: When mixed with cement and other materials, manufactured sand shows no significant difference from natural sand. Some mixtures may require slightly more water due to texture differences, but performance remains consistent.

What Are the Advantages of Sand Produced by a Sand Making Machine?

1. Uniform Composition: Raw materials are manually selected, resulting in a consistent mineral and chemical composition, which leads to better control and quality.

2. Adjustable Fineness Modulus: Unlike natural sand, which has a fixed fineness modulus, the sand making machine allows for manual control, offering flexibility for different construction needs.

3. Superior Adhesion & Strength: Curved and angular particles offer better adhesion to cement and higher compressive strength, making it ideal for high-performance concrete.

4. Acceptable Stone Powder Content: Although manufactured sand may have up to 20% stone powder, it does not adversely affect concrete's setting time or strength, and in some cases, it even improves performance.
