The sand produced by stone sand making is called machine-made sand. The modern sand-making process is very mature. Compared with natural sand, machine-made sand is not inferior to natural sand. It is used in many industries, especially construction, infrastructure and other engineering fields to replace natural sand. Different from natural sand, the production of machine-made sand has strong controllability. By adjusting the size of the inlet and outlet of the sand making machine, sand products with different particle sizes can be processed as required. The requirements for the particle size of the sand are strict. The advanced production line can introduce screening configuration, sand washing equipment, multiple screening, impurity removal and cleaning treatment, so that clean and high-quality high-grade sand and gravel can be obtained.
High-quality sand is pure and free of debris, and the particle size is uniform but not too powdery. Only this kind of sand can be used in high-level buildings, infrastructure projects and other fields. The working parameters of the sand making machine can be adjusted according to the actual production needs. Whether it is sand material shape or particle size specification, it can be realized by adjusting the configuration of sand making equipment and adjusting the operating parameters of the equipment. Compared with natural sand, machine-made sand has more specifications and better grain shape.
The sand processed by the stone sand making machine can be equipped with a variety of specifications according to the requirements of different particle sizes. There are actually many kinds of sand making equipment. Let us take the commonly used PLS impact sand making machine as an example, which can make sand and shape it, and the crushing effect Well, the material is discharged quickly, and the produced sand can be used instead of natural sand.
What are the advantages of the sand produced by the sand making machine?
1. Composition structure: The raw materials for processing and producing sand are all selected artificially, with uniform material, pure composition, consistent mineral composition and chemical composition, and are not as complicated as natural sand.
2. Fineness modulus: Generally, natural sand has only one fineness modulus, while the fineness modulus of sand making is controlled by people and can be adjusted according to needs through the adjustment process, which cannot be achieved by natural sand.
3. Adhesiveness and compressive strength: The particle size of machine-made sandstone is usually curved. When it is bonded with concrete and other structures, it will have stronger adhesion, stronger effect of compressive strength, and longer service life. longer.
4. Stone powder content: The large content of sand and stone powder is also an important feature different from river sand, but research shows that the content of general sand and stone powder does not exceed 20%, which has no adverse effect on the setting time and strength of concrete.
