Nowadays, machine-made sand is very popular, and many manufacturers have even put forward the slogan of perfectly replacing natural sand. So is that really the case? In fact, although some manufacturers deliberately exaggerate the role of machine-made sand, compared with the increasingly scarce natural sand, machine-made sand does have considerable advantages.

Shanghai KINGLINK has a deep understanding of the sand and gravel industry, and has rich practical experience. Today, let's popularize the differences among natural sand, machine-made sand and high-quality machine-made sand.

Three advantages of machine-made sand:

1. Quality advantage: the production mode of fixed material source and mechanization ensures the quality of machine-made sand is stable and the particle size is adjustable and controllable.

2. Quality advantages: hard texture, small mud content, high surface energy and hydrophilicity, and complete grading.

3. Resource advantage: It is not limited by the region, but can use local materials to utilize different mineral resources and even waste resources, which not only solves the problem of environmental pollution, but also improves the utilization rate of natural resources.

The machine-made sand is divided into ordinary machine-made sand and fine machine-made sand. What is the difference between them?

Fine machine-made sand refers to the rock particles that are crushed and screened by the crushing and sand making equipment, and meet the fineness modulus of 2.6~3.0, the stone powder content of 3%~8%, the accumulated screen residue of 1, 3, 6, 8, 9, the needle and flake shape of<8%, the water content of 3%~5% and other technical indicators. Compared with ordinary machine-made sand, it has the following advantages:

1. The concrete of high-quality machine-made sand has better initial slump performance, greater expansion, less time loss, and better concrete performance.

2. Due to the adoption of grading adjustment technology, the grading of high-quality machine-made sand is more reasonable, with less mud content and mud lump content. Therefore, the amount of concrete admixture is less.

3. The high-quality machine-made sand is in the shape of polyhedral circle, with reasonable grading, small void ratio, less mud content, better bonding ability with cement paste, and more dense concrete.

In a word, the application technology of high-quality machine-made sand in concrete is a mature technology, which can improve the working performance of concrete, improve the compressive strength of concrete, and improve the impermeability of concrete.

If you want to choose equipment that can produce high-quality machine-made sand, VSI series thin oil lubrication sand making machine designed and produced by Shanghai KINGLINK can provide you with fine quality and excellent grain size aggregate by upgrading the process, reducing costs and increasing efficiency.
